Sound Energy-Levings

What happens when two objects collide?

• Energy is changed into force.

• Energy is transferred from one object to another

• Energy is created and the objects move faster

• Energy is destroyed and the objects move slower

Which of the following Collisions would cause a still object to move at the speed of the object that hit it?

• collision of a moving object with a still object of the same weight.

• A collision of a moving object with a heavier still object.

• A collision of a moving object with a lighter still object.

• A collision of a large, light object and a still object that is smaller, heavier.

Look at the photograph of Gage hitting a golf ball with a golf club. Just as the photo was taken, the photographer heard a loud sound. Which BEST explains why the photographer heard a sound during the collision.

• Some of the energy transferred to the air.

• Some of the energy transferred to the ball.

• The motion of the club changed.

• The motion of the ball changes.

When a moving object collides with a still object of a different weight, the energy transfer can affect the objects' speeds

• The same

• different
