Term | Definition |
---|---|
kinematics | the study of motion |
average speed | the total distance divided by the total time |
distance | the total path length traveled by an object with no regard to direction |
displacement | straight line distance from start to finish with direction |
average velocity | total displacement of an object divided by the total time |
vector | a quantity that has a magnitude, unit, and direction |
scalar | a quantity that has a magnitude and unit but no direction |
position | the location of an object stated with straight line displacement from a reference point |
uniform motion | has constant speed in one direction |
instantaneous velocity | the velocity of an object at a particular instant in time |
acceleration | the change in velocity divided by the time interval |
freefall | motion of an object traveling under the influence of gravity alone |
