List 2
Term | Definition |
---|---|
Distance | how far an object has traveled |
Parabola | the path of a falling object (arc) |
Newton's Second Law | the net force on an object is equal to the product of its mass and its acceleration (F = m x a) |
Air Resistance | the frictional force that air exerts against a moving object |
Speed | distance divided by time |
Acceleration | the rate at which an object’s speed and direction (its velocity) changes |
Velocity | speed in a particular direction |
Sliding Friction | the resistance created by two objects sliding against each other |
Rolling Friction | the resistance created when a body (such as a ball, tire, or wheel) rolls on a surface |
Fluid Friction | the resistance to an object's motion through a liquid or gas |
