|
Acceleration |
The rate at which velocity changes with time; change may be in magnitude, direction, or both |
|
|
Inertia |
The property of things to resist changes in motion |
|
|
Mass |
The quantity of matter in an object. More specifically, the measure of inertia or sluggishness an object exhibits in response to ant effort made to start it, stop it, deflect it, or change its state of motion. |
|
|
Inversely |
When two values change in opposite directions so if one increases and other decreases by the same amount, they're inversely proportional to each other. |
|
|
Volume |
The quantity of space an object occupies |
|
|
Weight |
The force due to gravity on an object |
|
|
Kilogram |
The fundamental SI unit of mass. 1 kg is the mass of 1L of water at 4 degrees celcius |
|
|
Newton's 2nd Law |
Acceleration produced by a net force on an object is directly proportional to, same direction as, and inversely proportional to the mass of the object. |
|
|
Friction |
Resistive force that opposes the motion or attempted motion of an object past another with which it is in contact, or through a fluid. |
|
|
Free Fall |
Motion under influence of gravitational pull only |
|
|
Air Drag |
Frictional resistance due to motion through air |
|
|
Terminal Speed |
Speed at which the acceleration of a falling object terminates because air resistance balances its weight |
|
|
Terminal Velocity |
Terminal speed with direction of motion (down for falling objects) |
|
|
Tangenital Velocity |
Velocity that is parallel (tangent) to a curved path |
|
|
Universal Constant of Gravitation |
Every body in universe attracts every other body with mutually attracting force. For 2 bodies, this force directly proportional to product of their masses and inversely proportional to square of distance seperating them |
|
|
Inverse Square Law |
A law relating the intesity of an effect to the inverse square of the distance from the cause: Intensity ~ 1/distance^2 |
