Work, Force, and Power Concepts

Front

What is the formula for calculating power?

Back

Power (P) = Work (W) / Time (t)

Front

What is the unit of power?

Back

The unit of power is the Watt (W).

Front

What is the formula for work?

Back

Work (W) = Force (F) * Distance (d) or W = F * d.

Front

What is the unit of work?

Back

The unit of work is the Joule (J).

Front

What is the formula for force?

Back

Force (F) = Mass (M) * Acceleration (A) or F = M * A.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

If 150 J of work is needed to move a box 10 meters, what force was used?

Back

15 N

Front

What is the relationship between work, force, and distance?

Back

Work is done when a force moves an object over a distance.

Front

How do you calculate the power developed by a weight lifter?

Back

Power = Work / Time.

Front

What is the gravitational potential energy formula?

Back

Gravitational Potential Energy (PE) = Mass (m) * Gravity (g) * Height (h) or PE = mgh.
