In physics, velocity is speed in a given direction. Speed describes only how fast an object is moving, whereas velocity gives both the speed and direction of the object's motion.

Acceleration is the rate of change of velocity with time.
What is acceleration?
200
You measure velocity by dividing the distance travelled over the time taken to travel that distance.
How do you measure velocity?
200
You measure the distance from one point to another. Make sure you include the unit of measurement you used.
How do you measure the distance?
200
To calculate the speed you divide the change in distance over the change in time.
How do you find the speed?
200
You find the acceleration of something by diving the change in velocity over the change in time.
