Energy

What is kinetic energy?

• Energy an object possesses due to its motion

• Energy from food

• Energy from the sun

• Energy stored in an object

Define potential energy and give an example.

• Potential energy is the energy that an object has due to its color. For example, a red apple has potential energy because it can do work when it turns green.

• Potential energy is the energy that an object has due to its temperature. For example, a hot cup of coffee has potential energy because it can do work when it cools down.

• Potential energy is the energy that an object has due to its position or state. For example, a stretched rubber band has potential energy because it has the potential to do work when released.

• Potential energy is the energy that an object has due to its speed. For example, a moving car has potential energy because it can do work when it stops.

List three forms of energy.

• Kinetic, potential, thermal

• Light, magnetic, gravitational

• Solar, wind, nuclear

• Chemical, electrical, sound

What is the formula to calculate kinetic energy?

• 1/2 * mass + velocity^2

• mass + 1/2 * velocity^2

• mass * velocity^2

• 1/2 * mass * velocity^2

Explain the concept of potential energy.

• Potential energy is the energy that an object has due to its motion.

• Potential energy is the energy that an object has due to its position or state.

• Potential energy is the energy that an object has due to its color.

• Potential energy is the energy that an object has due to its temperature.

What are the different forms of energy?

• Kinetic, potential, thermal, chemical, electrical, and nuclear

• Red, blue, green, yellow

• Solid, liquid, gas, plasma

• Speed, distance, time, force

How do you calculate gravitational potential energy?

• GPE = mgh

• GPE = mgh^2

• GPE = m^2gh

• GPE = 2mgh

What is the formula for calculating mechanical energy?

• The sum of kinetic energy and potential energy

• The product of kinetic energy and potential energy

• The difference between kinetic energy and potential energy

• The quotient of kinetic energy and potential energy

Explain the concept of elastic potential energy.

• The energy stored in an object when it is at rest

• The energy stored in an object when it is heated

• The energy stored in an object when it is stretched or compressed

• The energy stored in an object when it is in motion

What is the relationship between mass and gravitational potential energy?

• Directly proportional

• Inverse proportional

• Exponential relationship

• No relationship
