A simple challenge activity to measure the air resistance on a basketball using video capture and analytical software - includes a sample student report.
This document discusses scientific units of measurement. It covers the metric system/SI system which is the international standard for measurement. The SI system is based on seven base units: meter, kilogram, second, Kelvin, mole, ampere, and candela. It also defines common metric prefixes like milli and kilo. Derived units are units like volume which are calculated from base units. Mass is distinct from weight, as weight depends on gravity. The document provides examples of unit conversions for length, volume, and mass within and between metric and US customary systems.
Physics is the study of the natural world and how physical objects behave. It began in ancient Greece when early scientists called "physikoi" tried to understand the natural world using observations and experiments. Today, physics involves measuring various quantities accurately using standardized metric units like meters, kilograms, and seconds. Measurements in physics consist of a number and a unit, and the International System of Units (SI) precisely defines the fundamental base units and derived units used in physics.
The presentation covers, Dimensions and standards, SI Unit system, Definition of basic units, SI Temperature Scale, Other Unit System, Non SI Units in common Uses, Scientific Notations, Prefixes, Significant figures

The document lists the 7 base SI units used in the international system of measurement: meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (thermodynamic temperature), mole (amount of substance), and candela (luminous intensity). It also defines the common metric prefixes and their meaning: kilo (103), hecto (102), deca (10), deci (10-1), centi (10-2), and milli (10-3).
Physical quantity is a quantity that has a numerical value and unit of measurement. Base quantities are quantities that cannot be defined in terms of other quantities, and include length, mass, time, current, temperature, amount of substance, and luminous intensity. Derived quantities are quantities that can be obtained and expressed in terms of base quantities or a combination of base quantities, such as velocity, acceleration, force, pressure, energy, power, frequency, volume, and area. Prefixes are used to indicate the multiple or sub-multiple of base units, with common prefixes including kilo, centi, milli, micro, and nano. Conversion between units requires identifying the appropriate conversion factors.
This document provides an overview of measurement and the metric system. It defines key terms like units, base units, derived units, and prefixes.

The document summarizes standards for weights measurement. It discusses that weight is a force with direction towards the center of Earth, and its SI unit is the Newton. It then describes kilogram standards which are cylinders of platinum-iridium alloy stored by BIPM. OIML weights up to 50kg meet quality standards and can calibrate other weights. There are two types of ASTM standards - type 1 are one-piece, most stable designs, while type 2 can use adjusting material as long as density remains stable. The document concludes with describing appropriate units (grams to kilograms and ounces to pounds) for small to large object weights.

The three fundamental SI units are outlined as the meter, kilogram, and second. Derived units are defined based on combinations of the fundamental units, such as meters/second for velocity. Several systems of units are described including the MKS, CGS, and FPS systems, with SI (metric) noted as the international standard. Conversions between units are demonstrated through examples. Dimensional analysis is introduced as a tool for checking equations and deducing relationships between physical phenomena.
This document provides an overview of the AS Level Physics course and discusses key concepts related to physical quantities, including:
1. Physical quantities can be quantified by measurement and have units associated with them. There are two types: base quantities and derived quantities.
2. Base quantities are the seven SI base units: length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. Derived quantities are formed by mathematical relationships between base quantities.
3. When writing the units of a derived quantity, the formula is used to express the units in terms of the base units. Examples of deriving units for acceleration, force, and pressure are provided.
Mass is the amount of matter in an object, while weight depends on both mass and gravity. Common tools for measuring mass include triple beam balances and beam balances. The triple beam balance uses sliding weights to balance the mass of an object, while the beam balance uses a central beam to measure mass. Mass is quantified using metric units like grams and kilograms, with the kilogram being the SI base unit of mass. Weight varies with changes in gravity, while mass remains constant regardless of location.
The document summarizes common units of measurement used in surveying for length, area, volume, weight, angles, temperature, and pressure. It provides conversion factors between British and metric units as well as between different units within each system of measurement. For example, it states that 1 foot is equal to 12 inches in the British system of length measurements and 1 meter is equal to 1000 millimeters in the metric system.

This document describes an experiment measuring how added weight affects the flight time of paper helicopters. Students tested paper helicopters with small (0.5g) and large (1.5g) paper clips attached. Their data showed that helicopters with more weight fell faster, supporting the hypothesis. Adding weight resulted in a negative correlation between weight and flight time.
Air resistance is the force exerted by air on a moving object, acting in the opposite direction of the object's motion. The larger the surface area of an object, the greater the air resistance, which is why leaves fall more slowly than acorns of similar mass. As an object falls through air, air resistance increases until it balances the force of gravity, at which point the object reaches its terminal velocity and stops accelerating further downward.
The document discusses air resistance and its effects on falling objects. It explains that air resistance acts in opposition to the force of gravity and depends on an object's speed, size, and shape. Specifically, it notes that crumpled paper falls faster than flat paper because it has less air resistance due to a smaller surface area. Finally, it introduces the concept of terminal velocity, which is the maximum speed an object can reach when air resistance equals the force of gravity.

The document discusses force, pressure, and friction. It defines force as a push or pull and explains that forces can change the speed, direction, or shape of an object. It also distinguishes between elastic and inelastic objects based on whether they return to their original shape after a force is applied. Friction is described as a force that opposes motion.
Forces can make objects move, change speed or direction, or deform shape. A force is measured in Newtons and can be exerted through contact or non-contact. Contact forces include tension, strain, and impact forces. Non-contact forces include magnetic, electrostatic, and gravitational forces. Magnetic forces involve attraction or repulsion between poles, while gravitational forces act between all masses and decrease with distance.
This document provides an overview of key concepts related to force and motion, including definitions and formulas. It defines a force as a push or pull and notes they have both size and direction. It explains net forces result from combining multiple forces and discusses balanced and unbalanced forces. Key terms like motion, speed, velocity, acceleration, inertia, and Newton's Three Laws of Motion are defined. Formulas for speed, acceleration, weight, and examples of applications of the three laws are also presented.
This document discusses key concepts around motion and forces including:
1) It defines speed, velocity, and the difference between the two.
2) It explains that unbalanced forces cause changes in an object's velocity or acceleration, while balanced forces do not cause changes.
3) It describes different types of friction including static, sliding, rolling, and fluid friction and factors that affect friction.
