Work Power Energy

What is the definition of work in physics?

• Work is the outcome of energy and power.

• Work is the product of force and distance.

• Work is the sum of mass and acceleration.

• Work is the result of speed and time.

Name the two main types of energy.

• Chemical energy and electrical energy

• Thermal energy and sound energy

• Nuclear energy and light energy

• Kinetic energy and potential energy

State the work-energy theorem.

• W = ΔPE

• W = ΔKE

• W = mv^2

• W = Fd

What is the formula for spring force?

• F = ax^2 + bx + c

• F = mx + b

• F = -kx

• F = kx

Define work in the context of physics.

• Work is the outcome of mass and acceleration.

• Work is the result of speed and time.

• Work is the product of force and displacement.

• Work is the combination of energy and power.

Describe the relationship between potential energy and kinetic energy.

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

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

• Potential energy is the energy related to an object's temperature.

• Potential energy is the energy associated with an object's shape.

How is potential energy defined?

• The energy of sound waves

• The energy stored in chemical bonds

• The energy of motion

• The energy an object possesses due to its position relative to other objects.

What is the connection between power and work?

• Power and work have no connection

• Power is the rate at which work is done

• Work is the opposite of power

• Power is only related to energy

Explain the concept of potential energy in physics.

• Potential energy is a type of energy that is only present in moving objects.

• Potential energy is a form of energy that is always converted into kinetic energy.

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

• Potential energy is the energy associated with the motion of an object.

What is the unit of work and energy?

• watt (W)

• newton (N)

• ampere (A)

• joule (J)
