Understanding Force, Work, and Energy

What is force?

• Force is a type of energy.

• Force is an interaction that causes an object to accelerate.

• Force is the weight of an object.

• Force is the speed of an object.

Can you name a type of force?

• Nuclear force

• Gravitational force

• Frictional force

• Magnetic force

What is work in physics?

• Work is the amount of force applied to an object.

• Work is the total energy stored in an object.

• Work is the speed at which an object moves.

• Work is the energy transferred when a force causes an object to move.

How is work calculated?

• Work = Distance / Time

• Work = Force / Distance

• Work = Force × Distance × cos(θ)

• Work = Force + Distance

What is energy?

• Energy is the speed of light.

• Energy is the capacity to do work or produce change.

• Energy is a form of currency.

• Energy is a type of matter.

What are the two main types of energy?

• Mechanical energy and electrical energy

• Kinetic energy and potential energy

• Thermal energy and chemical energy

• Nuclear energy and solar energy

How does energy change form?

• Energy remains constant and does not change form.

• Energy can only be destroyed, not converted.

• Energy can only be created, not transformed.

• Energy changes form through conversion and transformation processes.

What is potential energy?

• Potential energy is the energy of heat.

• Potential energy is the energy stored in an object due to its position or state.

• Kinetic energy is the energy of motion.

• Potential energy is the energy released during a chemical reaction.

What is kinetic energy?

• Kinetic energy is the energy stored in an object at rest.

• Kinetic energy is the energy released during a chemical reaction.

• Kinetic energy is the energy associated with an object's temperature.

• Kinetic energy is the energy of an object in motion.

Can you give an example of work being done?

• Reading a book

• Pushing a wall

• Sitting on a chair

• Lifting a box off the ground.
