## What force is it when two forces cancel each other out?

If two forces of the same strength push in opposite directions, they cancel each other out. Many objects have lots of different forces pushing or pulling them all at the same time. If all the forces pushing an object cancel each other out, the object does not move. We call this being balanced.

## When we push the wall the wall does not move and no work is done?

Answer: Even though the man exerts force on the wall , the wall does not move. Work done = force applied * displacement and since the displacement of the wall is zero. , work done is also zero.

## Why are forces always in pairs?

The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. “Forces always come in pairs — equal and opposite action-reaction force pairs.”

## Why does vertically falling rain make slanted?

“Vertically” falling rain makes slanted streaks on the side windows because with respect to the car the rain isn’t falling vertically. No need to involve wind here.

## When a coin is tossed upward what happens to its velocity while ascending its acceleration ignore air resistance?

As it goes up, the velocity decreases because the force of gravity is constantly pulling it down. The coin will eventually reach a maximum height, where its velocity will reach zero. Afterwhich, the velocity increases again as it goes back down to the ground.

## When you push downward on a book at rest on a table you feel an upward force does this force depend on friction defend your answer?

This reaction does not depend on the friction. In fact, friction acts whenever you try to move an object along a surface, in a direction parallel to the surface itself. In this case, instead, you are trying to push the object perpendicularly to the surface, not parallel: so, no friction acts when you push.

## When a cannonball is fired from a cannon which undergoes the greater acceleration?

The cannonball undergoes more acceleration than the cannon because its mass is much smaller. F represents both the action and reaction forces; m (large), the mass of the cannon; and m (small), the mass of the cannonball.
