Answer 1

force exist

Explanation:

1)we are able to stand and walk etc ..due to gravitational force

2)we are able to move due to kinetic force

3)magnets attract each other due to magnetic force

4)we are able to move or do some work due to muscular force

hops it helps ...

Answer 2

At first what is force?? The force is the sensation of push and pull exerted on a body and we can only feel it, there are different types of forces such as gravatational force,the force that is exerted on a body towards the centre of Earth,aplied force,tensional force etc. So force is the thing that can only we feel but can't see.

So the four ways that we can feel the force are-

• If you are in a car and the car takes turn they you will feel a shake, by this sensation you can feel force.

• If you take a spring and fixed it's one end at a fixed support and hang it's other end with a heavy object then you will see that the spring stretched.The spring stretched because we exert force in the spring, that's why.

• We see that when we push an object,it goes away from us at a certain distance and when we pull an object it comes nearer to us,the body moves because we exert force on it.

• There is gravitational force which attracts us towards it's centre because of mass,so we feel the force.

These are the four ways by which we know that forces exist.
