Explore free fall and gravitational motion

Front

Two objects of different masses falling freely near the surface of the moon would

Back

have same velocities

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.

Front

If a freely falling object were somehow equipped with a speedometer, its speed reading would increase each second by?

Back

about 10 m/s

Front

Which of the following statements applies to the motion of a ball tossed upward? I. It has constant acceleration on the way up II. It has constant acceleration at the top of its path III. It has constant acceleration as it moves downward.

Back

All are correct

Front

Which object would fall with greater acceleration in a vacuum - leaf or pebble?

Back

Both accelerate at the same rate

Front

If you throw a ball straight up, what is its velocity at the highest point?

Back

0.0 m/s

Front

A ball is tossed upward and caught at the same position of throw. In the absence of air resistance, the speed of the ball when it is caught would be

Back

the same as the speed it had when tossed upwards

Front

Where does a hammer fall faster if gravitational pull on the Moon is about six times weaker than on Earth?

Back

Earth

Front

The state that exists when the only force acting on an object is gravity is called

Back

free fall

Front

If an object is free falling onto the Moon, what happens?

Back

It would not encounter any air resistance.
