You must be able to explain! True or false: Potential energy is when something is sitting still, so the more potential energy it has, the slower it will go.
False: Potential energy is just the amount of kinetic energy an object will be able to use once it is moving. The more potential energy an object has, the FASTER it will go.

You're in the woods on a camping trip and it starts getting cold. You light a fire to create thermal energy. Before converting to thermal energy, what form of energy was used as the fire lit?
Chemical

Name the 3 things that can happen in a collision.
- Energy transfers from one object to another
- The collision can cause a sound
- The collision can cause a change in shape/dent

Ball A is sitting at the top of a 24 inch ramp. Ball B is sitting at the top of a 32 inch ramp. Ball C is sitting at the top of a 28 inch ramp. Which ball has the most potential energy? Explain
Ball B has the most potential energy because it is on the tallest ramp!

A skier is at the top of a snowy mountain about to start skiing.
1) Before he takes off, what kind of energy does he have?
2) After he takes off, what kind of energy does he have?
1) Potential
2) Kinetic

Solar power can cause trinkets to move back and forth. In this case, light energy converts into what form of energy?
Kinetic energy, because the light makes the trinket move

In which trial does the toy car have more energy? Give one piece of evidence, or TWO for extra points on this question.
Trial 2:
- The ramp is set higher, giving the toy car more potential energy in trial 2
- The block moves further after the collision, which would have required more kinetic energy

Two cars get in a head on collision. Car A is traveling 50 mph. Car B is traveling 30 mph. Which car will be more damaged after the collision?
Car B will be more damaged/dented because it was hit by a stronger force than car A was.

Sawyer is using his slingshot to shoot pebbles at glass bottles, but for some reason the pebbles aren't flying fast enough! What should Sawyer do to make the pebbles fly faster?
Sawyer should pull the slingshot back more.

I'M SO HUNGRY! I'm going to make some avocado toast!
1) What form of energy is used to start the toaster?
2) The make the toast, that energy converts to _____ energy.
1) Electrical
2) Thermal

What form of energy does a phone convert into electrical energy?
Chemical energy - it uses a battery

As the ball navigates through the maze, it switches back and forth between two forms of energy. What does the energy start as, and what is the other form it changes into as it goes from ramp to ramp?
The energy starts as potential, then changes to kinetic. As the ball falls to a ramp, its kinetic energy turns back into potential energy.

A metal ball rolls down a ramp and hits a glass cup, which makes a sound. If the scientist wants the sound to be louder, how should he change the experiment?
Raise the ramp higher so that the ball moves faster and hits the cup with more energy

3 skateboarders are practicing tricks in a skate park. Paul rolls at 12 mph off of a ramp. Grayson rolls at 9 mph off of a ramp. Joseph rolls at 14 mph off of a ramp. Who rolled off of the tallest ramp? How do you know?
Joseph rolled off the tallest ramp. We know this because his high amount of kinetic energy means he also had the highest amount of potential energy.

Name the two kinds of energy we get from the sun.
Light energy and thermal energy

A hamster runs on a wheel that is used to power a lightbulb. Go Hammy, go! The energy started in one form, then converted twice. What three forms of energy were used and in what order?
Kinetic -> Electrical -> Light

Which step should you drop a ball from to transfer the MOST kinetic energy to the sand?
Step W, because it is the highest and will have the most energy as it falls.

Jacob is using a slingshot to fire pebbles at a sheet of clay. He fires the pebbles at different speeds into the clay. If he fires faster, what will the effect be on the clay?
Firing pebbles faster at the clay will cause bigger dents in the clay.
