What is kinetic energy?
Q.This is stored energy due to an object’s position or condition
What is potential energy
This kind of energy is stored in the bonds between atoms in molecules.
A. Thermal energy
B. Kinetic energy
C. Chemical energy
D. Electrical energy
What is C
Q.Energy related to the motion of particles in a substance; the faster the particles move, the more of this energy the substance has.
What is thermal energy
Q.Kinetic energy depends on an object’s mass and its ______?
What is speed (or velocity)
Q.A book on a high shelf has this kind of potential energy because of its height.
What is gravitational potential energy
Statement:

Q.Statement:
You place a metal spoon and a wooden spoon in the same hot soup. The metal spoon quickly becomes hotter to the touch. Explain what this shows about metal compared to wood.
What is that metal is a better conductor of thermal energy than wood
Q: Between a moving truck and a moving bicycle going the same speed, which has more kinetic energy?
What is the truck?
Q.A stretched rubber band has this ? type of potential energy.
What is elastic potential energy
A phone battery powers the device because it turns this stored energy into electrical energy.
Choices:
A. Chemical energy
B. Thermal energy
C. Kinetic energy
D. Light energy
What is A
Q.A hot drink is left on a table and eventually becomes the same temperature as the room. Describe how thermal energy moves during this process.
What is thermal energy flows from the hotter drink to the cooler air until they reach the same temperature.
Q: If you double an object’s speed, what happens to its kinetic energy?
What is it increases a lot (it becomes four times greater)
Q.Two identical balls are on different shelves. Which one has more gravitational potential energy?
What is the ball on the higher shelf
Gasoline in a car engine is an example of this kind of energy that is converted into motion and heat.
Choices:
A. Potential energy
B. Chemical energy
C. Nuclear energy
D. Sound energy
What is B
Q.Statement:
You hold an ice cube in your hand, and it begins to melt. Describe the direction of heat transfer and what happens to the ice.
What is heat moves from your warmer hand to the colder ice, causing the ice to gain thermal energy and melt
Q: A ball is rolling across the floor and then slows down. What happens to its kinetic energy?
What is its kinetic energy decreases as it slows down
Q.At the top of a roller coaster hill, does the car have more kinetic energy or potential energy? Explain.
What is more, potential energy because it is high above the ground and not moving very fast?
Statement:
When a candle burns, its chemical energy is transformed mainly into these two kinds of energy.
Choices:
A. Thermal and light energy
B. Sound and nuclear energy
C. Kinetic and electrical energy
D. Gravitational and elastic energy
What is A
Q.Statement:
Two objects have the same temperature, but one contains much more thermal energy than the other. Explain how this is possible using the idea of mass or number of particles.
What is the object with more mass (more particles) has more total thermal energy, even though the temperature is the same?
