The work done by the motor per unit time is called _________.

Correct option is A

Correct Answer:A. Power

Explanation:
The work done by a motor per unit time is defined as power. In physics, power is the rate at which work is done or energy is transferred.

Key Points:

1. Definition of Power:

​$$P= \frac{W}{t}$$​​

Where:

• P = Power (in watts)
• W = Work done (in joules)
• t = Time (in seconds)
1. Practical Meaning: Power measures how quickly a motor can perform work. For example, a motor with higher power can complete the same task faster than a motor with lower power.

Other Options Explained:

• Energy: Refers to the capacity to perform work but does not indicate the rate at which work is done.
• Acceleration: Describes the rate of change of velocity, unrelated to work or power.
• Momentum: Refers to the product of mass and velocity, not work or power.
