Key words

Force  - Something that tends to cause a change in motion, measured in metres per secound squared (kg/ms-2).

Impulse - The effect of a force acting over a period of time.

Velocity (ms-1) - The rate of change of displacement or displacement divied by time, measured in metres per second.

Displacement - The shortest straight-line measurement between two points.

Acceleration (ms-2) - The rate of change of velocity or the difference between final and initial velocities divided by time taken, measured in metres per second squared.

Deceleration - A negative change in velocity over time or negative acceleration.
