Question

1. potential energy is...

a. the energy that gives an object the potential to move.
b. the energy an object has while moving.
c. the energy water has while it is boiling.

1. kinetic energy is...

a. the energy that gives an object the potential to move.
b. the energy an object has while moving.
c. the energy a skateboarder has at the top of a hill.

1. which object has no potential energy?

a. an apple hanging from an apple tree
b. a ball sitting on the ground
c. a skateboarder standing at the top of a hill

1. give two examples of kinetic energy from the selection.

a. a skateboarder rolling down a hill. a ball thrown in the air. a person throwing a ball, running around, or moving. a person moving. energy manifested as light, heat, and sound. water boiling.

1. give two examples of potential energy from the selection.

a. a skateboarder at the top of a hill. a skateboarder rolling down a hill. a baseball flying through the air. an apple hanging on a tree. a person.

Explanation:

1. Potential energy is the energy that gives an object the potential to move. It is stored energy based on an object's position or state.
2. Kinetic energy is the energy an object has while moving, related to its motion.
3. An object on the ground has no (or minimal) gravitational - potential energy relative to the ground level.
4. Examples of kinetic energy are objects in motion like a skateboarder rolling down a hill and a ball thrown in the air.
5. Examples of potential energy are objects in a position to do work like a skateboarder at the top of a hill and an apple hanging on a tree.

Answer:

1. a. the energy that gives an object the potential to move.
2. b. the energy an object has while moving.
3. b. a ball sitting on the ground
4. a. A skateboarder rolling down a hill. A ball thrown in the air.
5. a. A skateboarder at the top of a hill. An apple hanging on a tree.
