Force vs. Mass
Varying the amount of force or mass of an object affects the speed, direction, shape or orientation of an objects motion.
- Speed is a measure of how fast something moves a particular distance (for example, meters) over a given amount of time (for example, seconds).
- Therefore, speed is the rate of change of the position of an object, or how far something will move in a given period of time.
- Speed does not necessarily mean that something is moving fast.
