Science Exam - Energy and Motion

If an object is moving very fast, it has:

• very little energy.

• a large amount of energy.

• no energy.

To explain the relationship between speed and energy, one might observe that:

• a slowly rolling ball knocks over fewer pins than a fast-rolling ball.

• a stationary object has the most energy.

• speed and energy are unrelated.

One way energy can be transferred is through:

• complete stillness.

• sound waves.

• empty space with no medium.

Light is a form of energy that can be:

• only stored, not transferred.

• transferred from one place to another.

• created only by friction.

Energy is present when you observe:

• only objects at absolute zero temperature.

• a car moving down the street.

• a perfectly dark and silent room with no movement.

Heat is an indication that:

• energy is absent.

• energy is present.

• only cold objects exist.

When a bat hits a ball, what is primarily transferred from the bat to the ball?

• Matter

• Energy

• New atoms

A collision between two objects often results in a change in their:

• color.

• motion.

• mass.

Besides a change in motion, collisions can also produce:

• new elements.

• sound.

• a decrease in total energy.

If you hear a crash, it indicates that energy was transferred, partly in the form of:

• light.

• heat.

• sound.
