The document describes an experiment to test if throwing a paper airplane harder results in it traveling farther. It hypothesizes that throwing harder will cause it to go farther. The experiment tracks the distance the plane travels with soft, hard, and very hard throws. The results show that harder throws result in longer distances. The conclusion is that the experiment supports the hypothesis that harder throws allow the plane to travel farther due to the second law of Newtonian mechanics relating force, mass and acceleration.

The document outlines an experiment to test whether the amount of force used on a rubber band affects how far a paper airplane will fly. It lists group members, provides the question, hypothesis, materials, variables, procedure, and some initial data/observations from pulling the rubber band back with different amounts of force and attaching a straw. The goal is to launch paper airplanes with varying forces from a rubber band and measure the distance traveled to determine the effect of force.

Southern University and A&M College was established in 1880 in New Orleans, Louisiana by the state legislature through petitions from Black politicians and legislators to create an institution of higher education for African Americans. It first opened its doors on March 7, 1881 in New Orleans offering primary education through some college-level courses as well as vocational training. The university has since expanded its academic offerings and moved locations, with its current main campus located in Baton Rouge, Louisiana.

The student conducted an experiment to test how the force used to throw a paper airplane affects how far it flies. They hypothesized that throwing it hard would allow it to fly farther and faster. They tested throwing the airplane easy, hard, and very hard and measured the distance it flew. They found that the harder they threw it, the less distance it traveled, as more force led to less time spent in the air. This supported Newton's first law of motion that an object at rest wants to stay at rest unless acted on by an outside force.
To Buckle or Not to Buckle Marissa and Deondra
The document describes an experiment to test how Newton's first law of motion applies to seatbelt safety. The experiment involves pushing an egg in a shoebox into a wall with and without tape wrapped around the egg. When the taped egg was pushed, it did not break, while the untaped egg did break. This supported the hypothesis that the tape would act like a seatbelt in preventing the egg from breaking on impact. The conclusion is that seatbelts can prevent injury in a collision by holding occupants in place like the tape held the egg, demonstrating Newton's first law.

Egg Drop Janine, Tasia, Rose
This document describes an experiment to drop an egg into a glass of water without touching the egg. The group hypothesized that it is possible using something other than a hand to push the egg into the water. They used cardboard tubes of varying lengths placed on a pie pan with an egg to drop into a glass of water. Their observations showed that a longer tube resulted in a higher splash. Their conclusion was that the pie pan did not seem sturdy enough but the experiment was still easy, rating it a 5 on difficulty.
Creating infographics
The document provides tips for creating effective infographics, including ensuring the information is interesting and accurate, that the design has an appealing structure and is easy to use. It recommends using an inverted pyramid layout and the LATCH framework for organizing information with location, alphabetization, time, category, and hierarchy. The document cautions against cluttered or overly complex designs and stresses keeping the graphic simple with a clear purpose.

The experiment uses cardboard tubes of varying lengths placed over a glass of water, with an egg on top. When a pie pan under the tube is hit horizontally, the tube moves but the egg falls straight into the water without breaking. Videos show the egg successfully dropping into the water. The conclusion is that the egg can be dropped intact into water using this method, demonstrating Newton's first law of motion.

This document summarizes an experiment investigating Newton's first law of motion through the use of an uncooked egg, shoebox, and duct tape. The experiment involves placing the egg in the shoebox unrestrained and restrained with tape, and forcibly sliding the shoebox into a wall. When unrestrained, the egg cracked upon impact with the wall, but remained intact when restrained with tape, demonstrating that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force, in accordance with Newton's first law.

Egg Drop--Destiny, Tierney and Ginger
The document describes an experiment to test if an egg can be dropped into a glass of water without touching the egg. The hypothesis is that hitting the tin will likely cause the egg to crack on impact. The experiment uses cardboard tubes of different lengths on a pie tin, with an egg on top, over a glass of water. Hitting the tin horizontally allows the tube and egg to fall in without breaking due to inertia. The conclusion is that hitting the pie tin allows the egg to fall into the water through the demonstration of Newton's First Law of Motion.

This document discusses Newton's first law of motion, which states that an object at rest stays at rest and an object in motion stays in motion with constant velocity unless acted upon by an external force. It provides examples to illustrate this, such as a hovercraft moving at constant velocity, meaning no net external force is acting on it, and blocks sliding across different surfaces. It also discusses the concept of inertia and how it relates to an object's mass, with more massive objects being harder to accelerate. Newton's first law is known as the law of inertia because it describes an object's tendency to maintain its state of motion in the absence of external forces.
Maths and Physics
1) This document discusses the relationship between maths and physics. Mathematics allows physicists to calculate and equate physical events using equations that translate elements like forces, mass, and motion into numbers.
2) An example is provided of using mathematical equations to predict how an object sliding down an inclined plane will behave based on its mass, the inclination, and distance to the ground.
3) Physics relies heavily on mathematics to calculate and help understand phenomena like motion, forces, energy, and more. Mathematics provides the logical framework for physics.

Using Physical Principles and Measurements to Make a Prediction:
Target Practice with the Ballistic Pendulum
1 Introduction
Physics is an important science largely because it allows us to make accurate
predictions of objects’ behaviors in different situations. This idea has been
applied in the engineering of buildings, vehicles, and energy production. It is
used to design aircraft, plan space missions and execute battle plans in warfare.
In the first part of this lab you will make use of two of the most valuable
principles of physics, along with a couple basic measurements, to determine the
speed of the ball launched by the spring gun in your ballistic pendulum. In the
second part, you will calculate the point where the ball will strike when it is
fired without the catching pendulum in place. You will fire the gun to test the
accuracy of your predictions. Finally, you will do some simple analysis of the
cause of any inaccuracy in your calculated targeting.
Tips for success:
• Make all your measurements as carefully as possible.
The more accurate your measurements are, the closer you will
come to hitting your target.
• Pay attention to units.
Calculations require that all units match for the numbers to come
out right. For example, a distance may be recorded in meters,
centimeters, inches, miles, etc. The distance is fixed, but the
value of the number used to record it can vary greatly.
2 Using Conservation of Momentum and Con-
servation of Energy to measure the initial ve-
locity of the ball
Test fire your ballistic pendulum 3 or 4 times, observing the parts and
how the mechanism works.
Be very careful not to get in the path of the ball!
Directly measuring the ball’s velocity as it is fired by the ballistic pendulum
would be very difficult. However, since there are some physical properties that
are conserved, meaning that the total amount cannot change–only the form can
change or there can be a transfer from one object to another, the ball’s speed
can be determined quite accurately with only a couple simple measurements
1
and a couple short calculations.
How could you go about measuring the ball’s speed as it launches from
the ballistic pendulum?
Why would it be hard to use that method with this equipment?
2.1 Tracking the Energy
The act of firing the ball from the ballistic pendulum, and the different forms
that the energy involved takes during the process, can be viewed in four distinct
steps:
• Loading
• Firing
• Collision between the ball and pendulum
• Swing of the pendulum
Loading. To load the ballistic pendulum, you have to push the ball back
against a very stiff spring. In the process of doing this you use some of the
energy stored in your body. Once the pendulum is loaded, the energy that you
gave up is now stored in the compressed spring.It would be difficult to make
a measurement of the energy leaving your body during the compression of the
spring, but it is quite easy to put a number on the ener.

Experiment: Bouncing Golf Ball
Introduction
In this experiment we used the PASCO Science Workshop Equipment, KaliedaGraph, Microsoft Word and Excel, and a golf ball in order to investigate the potential, total, and kinetic energy of a ball that bounces off the ground. Our purpose is to determine as precisely as possible how much energy is lost in the bounce of the ball and to observe how well the energy is conserved throughout the flight. We believe that if the air resistance is neglected, then the ball that is dropped should conserve total energy as it falls. However, because the ground is not a totally elastic surface, some of the energy will be lost. We will therefore observe the total energy as a function of time so as to determine whether the energy is lost in the actual bounce of the ball into an inelastic surface, or due to air friction.
Procedure
First we needed to set up the equipment which contained a motion sensor and a golf ball. The golf ball was weighed and the height of the sensor, h, was measured with the digital meter on the sensor. The distance we are actually measuring, though, is the distance between the ground and the sensor because we are subtracting th ...
Physics - Chapter 6 - Momentum and Collisions
This document provides an overview of linear momentum and impulse. It defines momentum as the product of an object's mass and velocity (p=mv) and describes how momentum is a vector quantity. Impulse is defined as the change in momentum over time due to an external force (Impulse=Force x Time). The document explains how momentum is conserved in collisions and how the impulse-momentum theorem can be used to analyze collisions. It also distinguishes between perfectly elastic, perfectly inelastic, and inelastic collisions in terms of the objects' motions and changes to their kinetic energy before and after the collision.
3a. dynamics newtons laws
- Dynamics studies the causes of motion rather than just describing motion like kinematics. There are four fundamental forces - gravitation, electromagnetism, weak nuclear force, and strong nuclear force. Forces can be applied, thrust, weight, normal, elastic, tension, friction, air resistance, electric, or magnetic.
- Newton's three laws of motion are: 1) An object at rest stays at rest or an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. 2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, inversely proportional to the mass of the object. 3)
"Force and motion" is a power point for the 9th grade Physics students at the...
1) A force is any push or pull that causes an object to change its motion or shape. Forces come in pairs - whenever one object exerts a force on another, the second object exerts an equal and opposite force back.
2) Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass. Acceleration and net force always point in the same direction.
3) Newton's First Law says that objects at rest stay at rest and objects in motion stay in motion with the same speed and direction unless acted upon by a net unbalanced force.
Force and motion
A force is any push or pull that can cause an object to change its motion. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, as described by Newton's Second Law. Newton's Third Law states that for every action force there is an equal and opposite reaction force.

Universal Gravitation PPP
This document provides a detailed overview of universal gravitation and its discovery. It discusses how Kepler summarized astronomical data and formulated his three laws of planetary motion in the early 1600s. Newton then used thought experiments involving cannonballs to deduce that gravity causes objects to fall and that the force of gravity follows an inverse-square law, decreasing with the square of the distance between objects. The document also explains how Cavendish experimentally determined the gravitational constant G.
Force And Newtons Laws Of Motion
Newton's three laws of motion are summarized as follows:
1) Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2) Newton's second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
3) Newton's third law states that for every action, there is an equal and opposite reaction. Whenever one body exerts a force on a second body, the second body simultaneously exerts

Experiment: Bouncing Golf Ball
Introduction
In this experiment we used the PASCO Science Workshop Equipment, KaliedaGraph, Microsoft Word and Excel, and a golf ball in order to investigate the potential, total, and kinetic energy of a ball that bounces off the ground. Our purpose is to determine as precisely as possible how much energy is lost in the bounce of the ball and to observe how well the energy is conserved throughout the flight. We believe that if the air resistance is neglected, then the ball that is dropped should conserve total energy as it falls. However, because the ground is not a totally elastic surface, some of the energy will be lost. We will therefore observe the total energy as a function of time so as to determine whether the energy is lost in the actual bounce of the ball into an inelastic surface, or due to air friction.
Procedure
First we needed to set up the equipment which contained a motion sensor and a golf ball. The golf ball was weighed and the height of the sensor, h, was measured with the digital meter on the sensor. The distance we are actually measuring, though, is the distance between the ground and the sensor because we are subtracting th ...
Physics - Chapter 6 - Momentum and Collisions
This document provides an overview of linear momentum and impulse. It defines momentum as the product of an object's mass and velocity (p=mv) and describes how momentum is a vector quantity. Impulse is defined as the change in momentum over time due to an external force (Impulse=Force x Time). The document explains how momentum is conserved in collisions and how the impulse-momentum theorem can be used to analyze collisions. It also distinguishes between perfectly elastic, perfectly inelastic, and inelastic collisions in terms of the objects' motions and changes to their kinetic energy before and after the collision.
3a. dynamics newtons laws
- Dynamics studies the causes of motion rather than just describing motion like kinematics. There are four fundamental forces - gravitation, electromagnetism, weak nuclear force, and strong nuclear force. Forces can be applied, thrust, weight, normal, elastic, tension, friction, air resistance, electric, or magnetic.
- Newton's three laws of motion are: 1) An object at rest stays at rest or an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. 2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, inversely proportional to the mass of the object. 3)
"Force and motion" is a power point for the 9th grade Physics students at the...
1) A force is any push or pull that causes an object to change its motion or shape. Forces come in pairs - whenever one object exerts a force on another, the second object exerts an equal and opposite force back.
2) Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass. Acceleration and net force always point in the same direction.
3) Newton's First Law says that objects at rest stay at rest and objects in motion stay in motion with the same speed and direction unless acted upon by a net unbalanced force.
Force and motion
A force is any push or pull that can cause an object to change its motion. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, as described by Newton's Second Law. Newton's Third Law states that for every action force there is an equal and opposite reaction force.

Universal Gravitation PPP
This document provides a detailed overview of universal gravitation and its discovery. It discusses how Kepler summarized astronomical data and formulated his three laws of planetary motion in the early 1600s. Newton then used thought experiments involving cannonballs to deduce that gravity causes objects to fall and that the force of gravity follows an inverse-square law, decreasing with the square of the distance between objects. The document also explains how Cavendish experimentally determined the gravitational constant G.
Force And Newtons Laws Of Motion
Newton's three laws of motion are summarized as follows:
1) Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2) Newton's second law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
3) Newton's third law states that for every action, there is an equal and opposite reaction. Whenever one body exerts a force on a second body, the second body simultaneously exerts

- The maximum projectile distance is achieved at a 45 degree angle.
- Gravity accelerates objects at 9.8 m/s^2 near Earth's surface.
- Newton's three laws of motion explain forces like inertia, acceleration, and action-reaction pairs between objects in contact.
Atwood aircraft
The document summarizes a practicum report on experiments conducted using an Atwood aircraft. The report details:
1) The purpose of the practicum was to understand Newton's laws of motion and how acceleration, speed, and the pulley system work using an Atwood aircraft.
2) The Atwood aircraft consists of two masses connected by a rope over a pulley. Releasing the lighter mass causes it to accelerate down due to gravity, pulling the heavier mass up.
3) Experiments were conducted to measure acceleration and speed at different points along the track. The results were analyzed using equations for regular and changing motion related to Newton's laws.
Balanced and Unbalanced Forces.pptx

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

- 12. Newton second law Second law: The sum of the forces on an object is equal to the total mass of that object multiplied by the acceleration of the object. In more technical terms, the acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass. Thus, F = ma, where F is the net force acting on the object, m is the mass of the object and a is the acceleration of the object. Force and acceleration are both vectors (as denoted by the bold type). This means that they have both a magnitude (size) and a direction relative to some reference frame. !12
