Understanding the Concepts

* Power: The rate at which work is done. It's measured in Watts (W).

* Work: The force applied over a distance. It's measured in Joules (J).

* Force: A push or pull that can change the motion of an object. Measured in Newtons (N).

* Distance: The length of the path traveled. Measured in meters (m).

Calculations

1. Calculate the work done:

* Work = Force x Distance

* Work = 100 N x 10 m = 1000 J

2. Calculate the power:

* Power = Work / Time

* Power = 1000 J / 5 s = 200 W

Answer: The person would use 200 Watts of power to move the piano.
