Free Fall Acceleration

Front

In Newtonian physics, ________________ is any motion of a body where gravity is the only force acting upon it.

Back

free fall

Front

The standard acceleration due to gravity (or standard acceleration of free fall), is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as:

Back

9.8 m/s².

Juan drops his cell phone from the top observation deck of the Eiffel Tower at a height of 300 meters. How fast will the phone be traveling when it hits the ground? Ignore air resistance.

Back

76.68 m/s

Does free fall take into consideration the frictional force of air resistance?

Back

False

Front

If an object is in free fall for three seconds, how fast will it be falling?

Back

29.4 m/s

Front

If an object is free falling onto the Moon, which of the following would be correct?

Back

It would not encounter any air resistance.

Front

Do heavier objects free fall faster than lighter objects?

Back

False

Front

Which would hit the ground first if dropped from the same height in a vacuum—a feather or a metal bolt?

Back

They would hit the ground at the same time.
