When gravitational field does negative work, then P.E of body;
Correct answer: C. Must increase
- A. May increase
- B. May decrease
- C. Must increase
- D. Must decrease
Explanation
When gravity does -ve work "h" increases hence P.E increases.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.

Which one is not a unit of power?
Protons, electrons, neutrons, and particles have the same momentum. Which of them has the highest K.E?
What is the average power required to lift a mass of 100kg to a height of 50m in 50 Seconds?
Two equal masses are attached to the two ends of a spring of spring constant K. They are then pulled out symmetrically so that the spring extends by x. The work done by spring force on each block is:
By burning 1 g of coal, the energy produced is 2 kcal. Then for 1 kWh, the quantity of coal required will be nearly:
A block hangs freely from the end of a spring. A boy then slowly pushes the block upwards so that the spring becomes strain free. The gain in gravitational potential energy of the block during this process is equal to:
