Question

2 identify the following examples as either potential energy of kinetic energy. potential energy kinetic energy a boulder rolling down a hill an apple in a tree. a car parked on a hill. a meteor falling from the sky. a fully charged battery. a student running a race.

Explanation:

Step1: Recall energy definitions

Potential energy is stored energy, kinetic energy is energy of motion.

Step2: Analyze "A boulder rolling down a hill"

It is in motion, so kinetic energy.

Step3: Analyze "An apple in a tree"

It has stored energy due to height, so potential energy.

Step4: Analyze "A car parked on a hill"

It has stored energy due to position, so potential energy.

Step5: Analyze "A meteor falling from the sky"

It is in motion, so kinetic energy.

Step6: Analyze "A fully - charged battery"

It has stored chemical energy, so potential energy.

Step7: Analyze "A student running a race"

The student is in motion, so kinetic energy.

Answer:

A boulder rolling down a hill: Kinetic Energy
An apple in a tree: Potential Energy
A car parked on a hill: Potential Energy
A meteor falling from the sky: Kinetic Energy
A fully charged battery: Potential Energy
A student running a race: Kinetic Energy
