Exploring the Power of Running

What is power in physics?

Choose one:

• Energy
• Force
• Rate at which work is done or energy is transferred

Answer:

The correct choice is: Rate at which work is done or energy is transferred.

Power in physics is defined as the rate at which work is done or energy is transferred. It measures how quickly work is done or energy is transferred in a specific amount of time. In the context of running up the stairs, power would reflect how much work is done in a given time period, indicating the amount of energy exerted during the activity.

When comparing walking up the stairs to running up the stairs, the action that generates more power is running. This is because running involves exerting more force and doing more work in a shorter amount of time, resulting in a higher power output.
