Unit 3 Lesson 2 Collisions

Front

What is energy?

Back

Energy is the ability to do work or cause change. It can be transferred from one object to another.

Front

What happens during a collision?

Back

During a collision, two objects come into contact and can transfer energy, causing changes in their motion.

Front

What is transferred when a bat hits a ball?

Back

Energy is transferred from the bat to the ball.

Front

Why do objects change motion when they collide?

Back

Objects change motion because energy is transferred from one object to the other.

Front

What happens to a person standing still when they collide with a moving person?

Back

The person standing still may fly back due to the energy transferred from the moving person.

Front

If two marbles are moving at the same speed, which one has more energy?

Back

The larger marble has more energy.

Front

What does it mean when we say an object has kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

How does speed affect energy?

Back

As an object moves faster, it has more energy to transfer.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or condition.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transferred or transformed.
