Acceleration

Acceleration

If an object accelerates, its velocity increases.

Acceleration describes the change in an object’s velocity from slow to fast.

Deceleration

If the object decelerates, its velocity decreases.

Units

The units for acceleration are usually meters per second squared (m/s²).

Calculations

Acceleration can be calculated with the following formula:

Terminal Velocity of Falling Objects

Terminal velocity is the maximum speed a falling object can reach

A falling object will accelerate until it reaches terminal velocity

After reaching terminal velocity the falling object will no longer accelerate

All objects accelerate at the same rate aside from air resistance.

This rate is 9.8 m/s^2.
