Define energy
Energy is the ability to do work or cause change
What happens to the energy of objects when they collide?
The energy is transferred from one object to the other.
What is the correlation between particles and temperature.
The higher the temperature, the faster the particles move.
The lower the temperature, the slower the particles move.

What is the difference between a conductor and an insulator
A conductor is material that allows electrical current (electricity) to flow through it easily.
An insulator is a material that does not allow electrical current (electricity) to flow through it easily.
Who is correct? One student says a roller coaster traveling down the hill has potential energy. Another student says it has kinetic energy. Which student is correct?
Both students are correct. The roller coaster has kinetic energy because it is moving. However, it has potential energy because it still has more room to move.

Chloe and Natalia are bowling. Natalia grabs the bowling ball, walks up to the lane, swings her arm back then forward, and finally releases the ball. The ball hits the ground, rolls down the lane, and crashes into all of the pins. The pins fall to the ground and Chloe looks at Natalia amazed because she just got a strike.Natalia transfers the kinetic energy in her arm to the ball
the ball transfers kinetic energy into sound energy when it hits the ground and when it hits the pins
The pins transfer potential energy to kinetic energy when they fall down
Energy can be transferred through _________,
_________, ____________, and ______________.
Energy can be transferred through heat, sound, light, and electricity.
A hot pot is placed on a cold table. Where will the heat move?
To the cold table
