Question

3. What is elastic collision?

4. Give an example for a body whose centre of mass lies outside the body.

5. Name the SI unit of modulus of elasticity.​

Answer 1

Answer:

3.An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.

4.Centre of mass of a bangle lies at the centre of the bangle, which is outside the body.

5.Units of Modulus of Elasticity/Young's modulus are: Nm-2 or Pa

I think it's from class 11

1) An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy.
