Hey mates pls answer this questions class 9 force and laws of motion pls answer only if you know
Answers
Answer:
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Hope this could help you mark me as brainist and a thanks for ans please please
Explanation:
Force is defined as a push or pull on any object. It can change the velocity of an object with some mass .i.e, it can accelerate the mass.
Force=mass×acceleration
Newton derived three laws of motion.
1st law:
An object either remains at rest or continues to move at a constant velocity, unless an external force acts on it.
2nd law:
The force exerted on an object is equal to the rate of change of its momentum.
F=dp/dt
3rd law:
For every action,there is an equal and opposite reaction.
Note: Newton's laws are applicable only for external forces.
