Physics
Question | Answer |
---|---|
mechanics | study of motion |
motion | change of position |
kinematics | how things move |
dynamics | what causes motion |
displacement | change in position between two distinct points |
average speed | distance/time |
instantaneous speed | speed at any one moment |
uniformly accelerated motion | when the average acceleration and the instantaneous acceleration are the same |
velocity | displacement/ delta time |
scalar | one piece of information, a numerical value |
vector | two pieces of information, a direction and numerical value |
velocity-time | slope represents acceleration |
position-time | slope represents velocity |
average acceleration | delta v/ delta t delta change in velocity/ delta time interval |
acceleration | change in velocity with time |
