P4-Phys Sci-Falling Objects Test

Front

What happens to the velocity of a satellite in an elliptical orbit as it moves closer to Earth?

Back

The velocity of the satellite increases.

Front

What type of energy transformation occurs when a ball is dropped from a height?

Back

Potential energy is transformed to kinetic energy.

Front

How does the motion of a ball change if air resistance suddenly disappears?

Back

The ball would fall faster.

Front

Why do skydivers use parachutes?

Back

To decrease their kinetic energy.

Front

How does the mass of an object affect its acceleration due to gravity in a vacuum?

Back

All objects accelerate at the same rate regardless of their mass.

Front

What is gravitational potential energy?

Back

The energy an object possesses due to its position in a gravitational field.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

What is air resistance?

Back

A force that opposes the motion of an object through air.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is free fall?

Back

The motion of an object falling under the influence of gravity only.
