This document provides an overview of physics concepts including units of measurement in the MKS system, Newton's laws of motion, examples of forces, and other foundational topics. Key points covered include that physics links concepts to quantitative measurements using units; Newton's 2nd law states that force equals mass times acceleration; and his 3rd law that for every action there is an equal and opposite reaction. Gravity and its acceleration at the Earth's surface are also explained. Assignments given are to read chapters in the textbook and submit the first homework and questions/observations.
Forces can cause objects to move, change speed or direction, turn, bend or twist. Forces can be contact forces that act through direct physical contact, like pushing or pulling, or non-contact forces that act over a distance, like magnetism or gravity. Balanced forces cause no change in motion, while unbalanced forces cause acceleration or changes in speed or direction. Newton's three laws of motion describe how forces affect the motion of objects.

The document discusses Newton's laws of motion, including the definition of force, units of measurement for force, types of forces like friction and gravity, and Newton's three laws of motion - the law of inertia, the law of acceleration (F=ma), and the law of interaction (action-reaction forces). It provides examples and explanations of these fundamental physics concepts relating to force and motion.
Forces and motion can be described through Newton's three laws. A force is a push or pull that can cause an object to change its motion. Forces are measured in Newtons and can be combined, with balanced forces not changing motion and unbalanced forces causing acceleration. Friction opposes motion. Gravity pulls objects downward. Newton's first law states an object at rest stays at rest unless a force acts upon it. The second law relates force, mass, and acceleration. The third law states that every action has an equal and opposite reaction. Momentum is the product of mass and velocity and is conserved in a closed system.

Forces have both magnitude and direction.

Newton's second law relates the net force on an object to its acceleration using the formula F=ma. Newton's third law states that for every action there is an equal and opposite reaction. Gravity exists between all objects and increases with the mass of the objects and decreases with distance between them. Weight is the gravitational force on an object and depends on its mass and location. Tides are caused by the gravitational forces of the moon and the centrifugal force of the Earth's rotation creating bulges in the oceans.

This document discusses the differences between mass and weight, Newton and Einstein's theories of gravity, and how gravity works. According to Newton, gravity is a force that attracts objects with mass. Einstein viewed gravity as the warping of spacetime by massive objects. Under Einstein's theory, objects follow curved paths in spacetime rather than experiencing a gravitational force.
Newton's three laws of motion are summarized as follows:
1. 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. 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. For every action, there is an equal and opposite reaction.

Forces can be pushes or pulls that cause an object to accelerate or change motion. There are four fundamental forces in nature - gravitational, electromagnetic, strong nuclear, and weak nuclear. Newton's laws of motion describe how forces cause acceleration and changes in motion. Newton's first law states that objects in motion stay in motion unless acted upon by an unbalanced force. Newton's second law relates force, mass, and acceleration. Newton's third law states that for every action force there is an equal and opposite reaction force.

3) For every action, there is an equal and opposite reaction.
1) A force is a push or pull that can be measured in Newtons. Forces can combine and act in the same or opposite directions. Friction is a force that slows or prevents motion and depends on surface roughness and weight.
2) Gravity is the force of attraction between objects with mass. Newton's three laws of motion describe how forces affect motion. An object at rest or in motion stays at rest or in motion unless acted upon by an unbalanced force. The greater the mass of an object, the greater the force needed to accelerate or decelerate it. For every action force, there is an equal and opposite reaction force.
3) Centripetal force pulls objects toward the center of a
This document discusses Newton's three laws of motion and the law of universal gravitation. It explains that Newton's first law states that objects remain at rest or in uniform motion unless acted upon by an external force. The second law establishes the relationship between an object's mass, its acceleration, and the net force acting upon it. The third law states that for every action there is an equal and opposite reaction. It also describes how centripetal force causes objects to travel in circular paths and defines momentum, gravitational force, and Newton's law of universal gravitation.
1. Forces can cause objects to move, change speed, or change direction. They are measured in Newtons and represented by arrows.
2. Newton's Second Law states that acceleration is produced when a net force acts on an object, and is directly proportional to the net force and inversely proportional to the object's mass.
3. Newton's Third Law states that for every action force there is an equal and opposite reaction force. The total momentum of a system remains constant if no external forces act on it.
Newton's three laws of motion are summarized. Newton's First Law states that objects at rest stay at rest and objects in motion stay in motion unless acted upon by an unbalanced force. Newton's Second Law states that force equals mass times acceleration. Newton's Third Law states that for every action, there is an equal and opposite reaction. Examples are provided to illustrate each law, such as friction slowing moving objects or gravity accelerating objects at the same rate but with different forces depending on their mass.

Newton's three laws of motion describe the relationship between an object's motion and the forces acting upon it. The first law states that objects at rest will stay at rest and moving objects will keep moving unless acted on by an outside force. The second law relates the acceleration of an object to the net force acting on it and its mass. The third law states that for every action force there is an equal and opposite reaction force. These laws help explain phenomena in sports such as how starting blocks aid sprinting and how force generation allows football players to affect other players' motions.
- Gravitation is a phenomenon where objects are attracted toward Earth.
- Sir Isaac Newton first proposed the idea of universal gravitation after observing an apple fall from a tree.
- Gravitation is important because it causes planets to orbit the sun, tides, and binds objects to Earth.
- The motion of the moon around Earth is due to the centripetal force of Earth's gravitational attraction.
- While objects attract Earth due to gravitation, we don't see movement because Earth's mass is much greater.
- An object in free fall is only influenced by gravitational force toward Earth.

Units of Measurement
• Physics forms a link between the physical world
(concepts) and the mathematical world (quantitative)
• This inevitably involves measurements
– Measurements inevitably involve units
• We’ll stick to MKS (SI) units in this course
– MKS: meters; kilograms; seconds
– As opposed to cgs: centimeter; gram; seconds
• Distance in meters (m)
– 1 meter is close to 40 inches
• Mass in kilograms (kg)
– 1 kg is about 2.2 pounds
• Time in seconds (s)

Mass and Inertia
• Mass is how hard it is to get something to move
– Intimately related to the idea of inertia
– Effectively how many protons and neutrons in the thing
– Distinct from weight, which relates to gravity
• the same mass weighs different amounts on different planets
• Inertia relates to Newton’s first law of motion:
an object in motion will remain in that state of motion unless
acted on by an outside force
• This applies to being at rest as well as being in a
state of motion
– motion relative to what

Newton’s Second Law of Motion
• Okay, what about when there is an outside force?
– outside: not coming from within the body; an external agent
– force: something that pushes or pulls
• Then we have Newton’s Second Law of Motion:
• Great: now we have to talk about acceleration
– the rabbit hole gets deeper
– but first let’s give some examples of force…
F = ma

Examples of Force
• Examples:
– gravity exerts a downward force on you
– the floor exerts an upward force on a ball during its bounce
– a car seat exerts a forward force on your body when you
accelerate forward from a stop
– the seat you’re sitting in now is exerting an upward force on you
(can you feel it?)
– you exert a sideways force on a couch that you slide across the
floor
– a string exerts a centrally-directed (centripetal) force on a rock at
the end of a string that you’re twirling over your head
– the expanding gas in your car’s cylinder exerts a force against
the piston
• Note the syntax: Agent exerts directed force on recipient

Velocity and Acceleration
• Velocity is a speed and associated direction
– 10 m/s toward the north
– 50 m/s straight upward
• Acceleration is any change in velocity
– either in speed OR direction
• Acceleration measured as rate of change of velocity
– velocity is expressed in meters per second (m/s)
– acceleration is meters per second per second
– expressed as m/s2 (meters per second-squared)

The Force-Acceleration Connection
• Whenever there is a net force, there will be an
acceleration
– A ball thrown into the air has the force of gravity operating on
it, so its velocity continuously changes, resulting in a curved
path
– When you step on the gas, a forward force acts on your car,
making it speed up
– The force of gravity attracts the earth toward the sun. This
has the effect of changing the direction of earth’s velocity,
wrapping it into a circle around the sun (centripetal force)
– A car, slamming into the side of another car already moving
forward, will exert a sideways force, changing the traveling
car’s direction of motion
– When a bat hits a ball, the large momentary force results in a
large acceleration of the ball as long as contact is
maintained

All Forces Great and Small
• The relation, F = ma, tells us more than the fact that
force and acceleration go together
– the relation is quantitative, and depends on mass
• For the same applied force:
– a small mass will have a greater acceleration
– a large mass will have a smaller acceleration
• If you want the same acceleration, a smaller mass
requires a smaller force, etc.
– this then relates mass and inertia in an intimate way:
– how hard is it to get an object moving?
Force = massacceleration OR Force = massacceleration

Hold On a Second…
• I’ve got forces acting on me right now, but I’m not
accelerating anywhere
– very perceptive, and this is where the concept of net force
comes in
Force #1
Force #2
Total Force
Force #1
Force #2
Total Force = 0

Examples of Zero Net Force
• Sitting in your seat, gravity is pulling down on you,
but the seat reacts by pushing up on you. The forces
cancel, so there is no net acceleration
• Pushing against a huge crate, the force of friction
from the floor opposes this push, resulting in no net
force and thus no acceleration

Newton’s Third Law
• For every force, there is an equal and opposite force
– every “action” has a “back-reaction”
– these are precisely equal and precisely opposite
• You can’t push without being pushed back just as
hard
– in tug-of-war, each side experiences the same force
(opposite direction)
– when you push on a brick wall, it pushes back on you!

Wait: We cheated two slides back…
• When we drew the box and floor, with the “normal”
force from the floor canceling the force of gravity,
these weren’t strictly force pairs
– but these are the two canceling forces on the box that result
in zero acceleration of the box
• The real pairs have to involve the earth:
box
floor
earth
satellite
• Force Pairs:
• earth-box (grav)
• box-floor (contact)
• earth-satellite (grav)

Don’t all forces then cancel?
• How does anything ever move (accelerate) if every
force has an opposing pair?
• The important thing is the net force on the object of
interest

Gravity
• One of the most apparent forces in our daily
experience is gravity
• Gravity is the mutual attraction of mass
– it’s always attractive, never repulsive
– all particles in the earth attract all particles in your body
– net effect (force) is effectively toward the center of the earth
• Follows force law elucidated by Newton:
Fgrav = GMm/r2
– where M is mass of earth, m is mass of you (or object of
interest), and r is distance (separation) between object and
earth’s center. G is just a constant: 6.6710-11 in MKS units
– Note that since F = ma, we can say
agrav = GM/r2 is the acceleration due to gravity

Gravity on earth’s surface
• The product, GM, for earth, is 3.9861014 m3/s2
– so agrav evaluates to 9.8 m/s2 on earth’s surface (r = radius of
earth = 6,378 km)
• Bottom line: falling objects accelerate at 9.8 m/s2 on
the surface of the earth
– downward velocity changes by about 10 m/s with each
passing second
• This also means that to support a 1 kg book against
the pull of gravity, one must exert F = ma =
(1kg)·(10m/s2) = 10 Newtons of force
– this is the object’s weight: mg
• Support for the book is just the “normal” force
required to keep the book from accelerating
– in other words: to make the net force on the book zero

Pressure, Density
• Pressure is force per unit area
– measured in N/m2, or Pascals (Pa)
– the pressure of the atmosphere at sea level is about 105 =
100,000 Pa (about 14.6 pounds per square inch—psi)
• pounds are also a unit of force, like the Newton
• Density is mass per volume
– measured in kg/m3
– water is 1000 kg/m3 (same as 1 g/cm3 in cgs units)
– air is about 1.3 kg/m3
– rock is 3300 kg/m3
– gold is about 19,300 kg/m3
