Question

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

O The force of gravity causes it to accelerate.
O It falls at a constant velocity.
O Its mass doubles for every second it falls.
O It changes direction every 9.8 meters.

Answer 1

#1.The force of gravity causes it to accelerate

Step-by-step explanation:

As acceleration is the rate of change in velocity of an object with respect to time. ... The acceleration of penny is due to the force of gravity. Thus, we can conclude that the force of gravity causes it to accelerate.
