Which of the following statements about power is true?
Correct Answer: Power can be negative.
- Step 1: Understand what power means. Power is the rate at which work is done or energy is transferred.
- Step 2: Know that work can be done in different directions. When work is done in the same direction as motion, power is positive.
- Step 3: Learn that when work is done against the direction of motion, like in the case of friction, power can be considered negative.
- Step 4: Conclude that since power can be negative when work is done against motion, the statement that power can be negative is true.
