Q:

Consider the following statements :

1. There is no net moment on a body which is in equilibrium.

2. The momentum of a body is always conserved.

3. The kinetic energy of an object is always conserved.

Which of the statements given above is/are correct?

A) 1, 2 and 3 B) 2 and 3 only
C) 1 and 2 only D) 1 only
 
Answer & Explanation Answer: C) 1 and 2 only

Explanation:

There are two conditions that must be met for an object to be in equilibrium. The first condition is that the net force on the object must be zero for the object to be in equilibrium. If net force is zero, then net force along any direction is zero.

Kinetic energy (KE) is the energy of motion, and kinetic energy is not always conserved in a collision

Energy and momentum are always conserved.
