Which of the following quantities measured from different inertial reference frames are same?
Updated On: Aug 22, 2024
- Force
- Velocity
- Displacement
- Kinetic energy

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In an inertial frame, an object or body accelerates only when a physical force is applied and in the absence of a net force, a body at rest will remain at rest and a body in motion will continue to more uniformly. Kinetic energy being a scalar quantity, hence measured from different inertial frame gives the same value, while the other three being vector quantities their values vary.

Concepts Used:
Kinetic energy
Kinetic energy of an object is the measure of the work it does as a result of its motion. Kinetic energy is the type of energy that an object or particle has as a result of its movement. When an object is subjected to a net force, it accelerates and gains kinetic energy as a result. Kinetic energy is a property of a moving object or particle defined by both its mass and its velocity. Any combination of motions is possible, including translation (moving along a route from one spot to another), rotation around an axis, vibration, and any combination of motions.
