Question

(a) State Newton's law of gravitation? Why it is called universal law of Gravitation-
(b) Explain in brief (i) Kinetic Energy (1) Porential Energy of a body.​

Answer 1

Answer:

option b is correct answer

Explanation:

kinetic energy

Answer 2

Answer:

b) 1. Kinetic energy is the energy possessed by a body by virtue of its motion. All moving bodies have kinetic energy.

2. The energy possessed by a body by virtue of its specific position (or changed configuration) is called the potential energy.

Formula - W = mgh

Types of Potential energy :-

1. Gravitational Potential energy - We define this energy as the energy which an object possesses when it has risen to a particular height against gravity.

2. Elastic Potential energy - Elastic potential energy refers to the energy which is stored in objects which we can compress or stretch like rubber bands, trampoline and bungee cords.
