Question

What happens if penny is dropped from a height of 20 meters?

It changes direction every 9.8 meters

the force of gravity causes it to accelerate

the falls at a constant velocity

it's mass doubles every second it Falls

Answer 1

The force of gravity will cause it to accelerate.

Answer 2

the force of gravity causes it to accelerate

Step-by-step explanation:

An object which is dropped from a certain height has an uniformly accelerated motion, with constant acceleration of 9.81 m/s^2, downward. This acceleration is due to the force of gravity, which pushes the object downward. As a result of the force of gravity, the object will have an acceleration, as stated in Newton's second law:

`F=ma`

where F is the force exerted on the object, m is the mass of the object and a is its acceleration.
