Energy Review

The video tutorial covers five forms of energy: mechanical, nuclear, heat, chemical, and electromagnetic. It delves into kinetic energy, influenced by mass and velocity, and potential energy, including gravitational potential energy. The tutorial also explains energy conversions and the law of conservation of energy. It encourages viewers to consider how energy impacts daily activities, such as using lights, eating, or exercising.

What two factors does kinetic energy depend on?

• Height and time

• Mass and height

• Mass and velocity

• Velocity and time

Gravitational potential energy is a type of which broader category of energy?

• Chemical energy

• Potential energy

• Kinetic energy

• Nuclear energy

What does the law of conservation of energy state?

• Energy can be transformed but not created or destroyed

• Energy is only conserved in closed systems

• Energy is always lost in conversions

• Energy can be created and destroyed

Which activity is NOT mentioned as a way to think about energy in everyday life?

• Driving a car

• Going for a run

• Eating food

• Turning on a light
