Module 1 Science Review

Front

What does it mean when a horse is accelerating?

Back

It means the horse is changing its speed, which can include speeding up or slowing down.

Front

What force is responsible for stopping a moving truck?

Back

Friction is the force that opposes motion and can stop a moving truck.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of a moving object.

Front

True or False: Kinetic energy is transferred from a bowling ball to a bowling pin during a collision.

Back

False. Kinetic energy is transferred from the ball to the pin.

Front

Which wagon has the most kinetic energy: a wagon moving at 2 m/s, 4 m/s, 6 m/s, or 8 m/s?

Back

A wagon moving at 8 meters/second has the most kinetic energy.

Front

What is the definition of friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What happens to kinetic energy when an object slows down?

Back

The kinetic energy decreases as the object slows down.

Front

What is the relationship between mass and kinetic energy?

Back

The more mass an object has, the more kinetic energy it has at the same speed.
