Flipping Physics Introduction to Power

Yeah, "Bobby", what's the difference?

What is the definition of power in physics?

• The total amount of work done.

• The rate at which work is done.

• The force applied over a distance.

• The change in velocity over time.

Look at you! Did you get all those answers correct before he even asked them?

What are the standard SI units for power?

• Joules (J)

• Newtons (N)

• Watts (W)

• Meters per second (m/s)

Which of the following is an alternative equation for power, relating force and velocity?

• P = Fd cosθ

• P = Fv cosθ

• P = mv²

• P = ma

What type of physical quantity is power?

• A vector quantity

• A scalar quantity

• A fundamental quantity

• A derived vector quantity

If we define Work to be a change in energy, what is one more equation we can use to find Power?
