Question

Which type of force does not change the state of rest of motion of an object and which type of force brings it in motion?

Answer 1

I think
It is inertia of rest by virtue of which a body cannot change its state of rest
And
It is inertia of motion by virtue of which a body cannot change its state of motion.

Answer 2

Answer:

1) balanced force 2) unbalanced force

Explanation:

this is because when its balanced force the forces are equal and there is no change in state of motion of an object , that is if its in rest , it will be in rest , in motion it will be in motion . On the other hand , unbalanced forces are when the forces(remember more than one) acting on object are not equal, so in the direction of the greater force the object starts moving.
