Calculate the acceleration from velocity and time, with different units. The acceleration is e.g. needed to determine the force which acts on a mass. A mass, on which no physical force acts, is at rest or in a constant movement.
The formula for the acceleration is a=v/t, the unit is m/s². The velocity v means the increase in speed in the time t. g is the average gravitational acceleration on Earth.
Example: a car, which accelerates in 8 seconds from zero to 100 km/h, has an acceleration of about 3.5 m/s².
