Key Points
- Speed is the scalar measure of the rate of movement of a body expressed either as the distance traveled divided by the time taken.
- Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
- Displacement is a vector quantity that refers to "how far out of place an object is".
- It is the object's overall change in position.
- Average speed is the average of all instantaneous speeds. It is found simply by a distance/time ratio.
- Velocity is defined as a vector measurement of the rate and direction of motion of an object.
- Velocity formula when an object moving in a straight line: r = d / t.
- r is the rate or speed, d is the distance moved, t is the time it takes to complete the movement.
- Velocity formula when an object moving in a straight line: r = d / t.
- A body moving with a constant speed has velocity without acceleration.
