An elevator is moving upwards with constant velocity of 'v'. What is the weight of a person of a mass 'm' inside the elevator during upward motion?
Correct answer: B. mg
- A. mg + mv
- B. mg
- C. mg ― mv
- D. Zero
Explanation
The weight of an object is defined as the force of gravity on the object and is calculated as the mass times the acceleration of gravity, w = mg. This does not change when the elevator is moving because it doesn't effect the mass of the person and the gravitational acceleration.
