Key terms | meaning |
motion | change in position in a certain amount of time |
frame of reference | the background or point that is stationary; compare to describe motion between objects |
kinematics | study of how things move |
dynamic | why does something move |
statics | when objects are at rest and unchanging; equilibrium |
linear motion | moving in a straight line |
angular motion | an object moving in a circular motion |
periodic motion | repeating motion |
speed | rate which an object moves; speed=distance/time |
constant speed | speed that does not change |
average speed | dividing the total distance to the total time |
instantaneous speed | the speed an objects has for a certain amount of time in a certain point in time |
displacement | the distance from when an object starts and stops; displacement= final position - starting position |
velocity | speed in a given direction |
average velocity | displacement divided by time interval |
Acceleration | a change in rate of velocity; (final velocity - start velocity)/time |
Deceleration | when acceleration is negative |
momentum | the mass of an object times its velocity |
impulse | describe a time change of momentum |
conservation of momentum | an object's momentum is changed due to an outside force |
angular momentum | an object moving around a fixed point |
