Which energy varies with an object's height?
RRB Group D
11/10/2018 / Shift-I
2018
✓ Answer:DPotential energy
Gravitational potential energy is U = mgh.
222
Which of the following can neither be created nor destroyed?
RRB Group D
16/10/2018 / Shift-III
2018
✓ Answer:CEnergy
Energy is conserved, although it can change from one form to another.
223
Turbines use flowing water and air to convert:
RRB Group D
16/11/2018 / Shift-III
2018
✓ Answer:CKinetic energy into electrical energy
The motion of water or air drives a turbine coupled to a generator, converting kinetic energy into electricity.
224
When a bullet is fired, how does its kinetic energy compare with that of the recoiling gun?
RRB Ministerial & Isolated Categories (Primary Teacher); RRB Group D
11/09/2025 / Shift-II; 22/09/2018 / Shift-I
2025; 2018
✓ Answer:CMore than the gun
The gun and bullet have equal momentum magnitudes. Since K = p²/(2m), the lighter bullet has greater kinetic energy.
225
A 12 kg object is 5 m above the ground. Find its energy. (g = 9.8 m/s²)
RRB Group D
12/10/2018 / Shift-I
2018
✓ Answer:D588 J
U = 12 × 9.8 × 5 = 588 J.
226
An object is dropped from a height. Which energy does it have immediately before touching the ground?
RRB Group D
18/09/2018 / Shift-II
2018
✓ Answer:CKinetic energy
Gravitational potential energy has been converted into kinetic energy during the fall.
227
Mechanical energy minus kinetic energy equals:
RRB Group D; RRB Group D; RRB Group D
19/09/2018 / Shift-III; 12/10/2018 / Shift-II; 16/11/2018 / Shift-III
2018
✓ Answer:BPotential energy
Emechanical = K + U, so Emechanical - K = U.
228
What happens to the total energy of a body falling freely toward the earth?
RRB Group D
13/12/2018 / Shift-II
2018
✓ Answer:AIt does not change.
Neglecting air resistance, gravitational potential energy changes into kinetic energy while total mechanical energy stays constant.
229
_____ is known as the capacity of an object to do work.
RRB Group D
27/09/2018 / Shift-I
2018
✓ Answer:AEnergy
Energy is the capacity to do work.
230
Mechanical energy is a combination of kinetic energy and:
RRB ALP & Technician; RRB ALP & Technician
10/08/2018 / Shift-II; 13/08/2018 / Shift-III
2018
✓ Answer:CPotential energy
Mechanical energy = kinetic energy + potential energy.
