Speed & Velocity
Term | Definition |
---|---|
Speed | the rate at which a distance is traveled |
Velocity | the speed and direction of moving obejects |
Acceleration | a change in velocity over time |
Motion | a change in the position of an object compared to another object |
Distance | the amount of space between one point and another |
Force | an interaction between objects that causes a change to the objects' motion |
Acceleration due to Gravity | the change in velocity caused by a gravitational force |
Constant Speed | means that the object's speed does not change. Therefore, there is no acceleration, or decceleration. |
Constant Velocity | occurs when an object moves from one location to another without a change in speed or direction (i.e. acceleration in all directions is 0). |
