Class 11 Physics simulations · Work, Energy and Power

Power of a lifting motor

Raise a load at constant speed and compare work with the rate of doing work.

Open the simulation

What to notice

A faster motor does the same work over the same height in less time.

Key relation

P = Fv = mgv

Try this

Double lifting speed and compare power and total work.

What you can change

• Load mass: 20 to 100 kg
• Lifting speed: 0.2 to 2 m/s
