Understanding Energy and Motion

What is energy?

• The ability to do work or cause change.

• A type of force.

• The speed of an object.

• The mass of an object.

Which of the following is an example of kinetic energy?

• A book on a shelf.

• A moving car.

• A compressed spring.

• A charged battery.

What is the formula for work?

• Work = Force + Distance

• Work = Force × Distance

• Work = Force ÷ Distance

• Work = Force - Distance

What happens to kinetic energy (KE) as potential energy (PE) decreases?

• KE decreases.

• KE remains the same.

• KE increases.

• KE becomes zero.

Which type of energy is stored in the nucleus of atoms?

• Chemical energy

• Electrical energy

• Nuclear energy

• Thermal energy

What is the relationship between gravitational potential energy (GPE) and height?

• GPE decreases as height increases.

• GPE remains constant regardless of height.

• GPE increases as height increases.

• GPE is not related to height.

Which of the following is an example of energy transformation?

• Heat moving from a stove to a pot.

• Sunlight converting into chemical energy in plants.

• A ball rolling down a hill.

• A battery powering a flashlight.

What is power in terms of work and time?

• Power = Work × Time

• Power = Work ÷ Time

• Power = Work + Time

• Power = Work - Time

Which of the following energy types can be both potential and kinetic?

• Light energy

• Sound energy

• Mechanical energy

• Nuclear energy

What is the difference between energy transformation and energy transfer?

• Transformation is energy moving between objects; transfer is energy changing forms.

• Transformation is energy changing forms; transfer is energy moving between objects.

• Both involve energy changing forms.

• Both involve energy moving between objects.
