Lesson: Acceleration over Time High School PhysicsPhysics
In this lesson, we will learn how to analyze the motion of objects that change their velocity in some amount of time, by using the formula for acceleration, a = ∆v/∆t.

A train has a velocity of 35 m/s when it reduces its engine power, and after 5 seconds the train has a velocity of 11.5 m/s. What is the train’s average acceleration in its direction of motion?
A skydiver accelerates downward at a rate of 9.8 m/s2. How much does their downward velocity increase in 0.67 seconds? Round your answer to two decimal places.
A cyclist accelerates at 2.3 m/s2. How much time is needed for the cyclist to increase their velocity by 9.43 m/s?
