There are four types of forces in nature
- Gravitational force
- Electromagnetic force
- Strong nuclear force
- Weak nuclear force
We have to learn before it some point
Force: when you push or pull some object you exert a force on it. is known as force
Can nonliving bodies exert a force, yes: if you run your hand into a wall, the wall exerts an equal force in the opposite direction on your hand.
Newton’s third law of motion: If a body A exerts a force F on another body B, the B exert a force -F on A.
Gravitational force | गुरुत्वाकर्षण बल
Everybody in the world pulls every other body towards itself with full force this force is directly proportional to the product of masses of both objects, it is inversely proportional to the square of the distance between them
