Lesson 2 Review

What type of energy is associated with motion?

• Potential Energy

• Chemical Energy

• Kinetic Energy

• Elastic Energy

Which of the following is an example of potential energy?

• A moving car

• A stretched rubber band

• A swinging baseball bat

• A rolling ball

What happens to the potential energy of a rubber band when it is released?

• It remains the same

• It transforms into kinetic energy

• It transforms into chemical energy

• It disappears

Which form of potential energy is stored in the bonds between atoms?

• Gravitational potential energy

• Electrical potential energy

• Chemical potential energy

• Elastic potential energy

What is gravitational potential energy?

• Energy due to an object's position relative to Earth

• Energy due to an object's motion

• Energy due to an object's temperature

• Energy due to an object's chemical composition

What happens to a pencil's potential to do work if it is dropped from a higher position?

• It decreases

• It remains the same

• It increases

• It disappears

What does the kinetic energy of an object depend on?

• Only the mass of the object

• Only the speed of the object

• Both the mass and speed of the object

• Neither mass nor speed

Which of the following will increase an object's kinetic energy more significantly?

• Increasing the object's mass

• Increasing the object's speed

• Decreasing the object's mass

• Decreasing the object's speed

What is the equation for kinetic energy?

• kinetic energy = (1/2) × mv²

• kinetic energy = m × v

• kinetic energy = m + v

• kinetic energy = (1/2) × m²v

What is the formula for calculating kinetic energy?

• (1/2) × mv²

• mgh

• mv

• (1/2) × mgh
