Question

A rock is dropped from a bridge what happens to the magnitude of the acceleration

Answer 1

9.81 m/s² constant

Step-by-step explanation:

Any object which is falling has only the acceleration due to gravity acting on it. The value of acceleration due to gravity is 9.81 m/s² which is constant. This is the case if air resistance is not taken into consideration.

The air resistance is a result of the surface area of the object which is falling. This will slow down the object and the velocity reached is called the terminal velocity.
