Term | Definition |
motion | The state in which one object's distances from another is changing |
reference point | a place or object used for composition to determine if an object is in motion |
average speed | the total distance traveled divided by the total time elapsed |
instantaneous speed | the speed of an object at one instant in time |
speed | the distance an object travels per unit in time |
velocity | speed in a given direction |
slope | the steepness of a line of a graph, equal to its vertical change divided by its horizontal change |
acceleration | the rate at which velocity changes |
force | a push or pull exerted on an object |
unbalanced force | force that produce nonzero net force, which changes the object's motion |
balanced force | equal forces acting on an object in opposite direction |
newton | a unit of measure equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second |
net force | the overall force acting on an object |
friction | the resistance that one surface or object encounters when moving over another |
static friction | friction that acts on objects that are not moving |
gravity | the force that pulls objects toward each other |
sliding friction | friction that occurs when one solid surface slides over another |
rolling friction | friction that occurs when one solid rolls over a surface |
fluid friction | friction that occurs when an object moves through a fluid |
air resistence | the fluid friction experienced by objects falling through air |
free fall | the motion of a falling object when the only force acting on its gravity |
terminal velocity | the greatest velocity a falling object can achieve |
inertia | the tendency of an object to resist any change in its motion |
momentum | the product of an object's mass and volecity |
Law of Conservation of Momentum | the rule that in the absence of outside forces the total momentum of objects that interact does not change |
