 # When A Force Acting On A Body Has Equal And Opposite Reaction Then Why Does The Body Move?

## What are the forces that act on the ball?

The forces are the weight, drag, and lift.

Lift and drag are actually two components of a single aerodynamic force acting on the ball.

Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion..

## When can a body stay at rest even though forces act on it?

The first law states that a body at rest will stay at rest until a net external force acts upon it and that a body in motion will remain in motion at a constant velocity until acted on by a net external force. Net external force is the sum of all of the forcing acting on an object.

## When two or more forces act on a body it forms?

When more than one force acts on an object, the forces combine to form a net force. The combination of all the forces acting on an object is the net force.

## What are the forces that act on a body to change its state of motion?

The force responsible for changing the state of motion of objects in all these examples is the force of friction. It is the force of friction between the surface of the ball and the ground that brings the moving ball to rest.

## Can an internal force change the velocity of a body?

No, internal forces cannot change the velocity of a body.

## Why does an object move if the action reaction forces are equal?

Balanced forces are equal and opposite forces that act on the same object. That’s why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don’t cancel out. In fact, they often result in motion.

## Why does Newton’s third law work?

Newton’s Third Law works because the universe tries to be fair. If you push against something it makes no sense not for it to push back against you. Your hand pushes on the table, and the table pushes back just as hard against your hand. If it didn’t push back, your hand would go straight through the table.

## Are action and reaction forces equal?

Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. … Forces always come in pairs – equal and opposite action-reaction force pairs.

## How do things move if the forces are balanced?

Balanced forces do not change the motion of an object. … If an object is in motion, it will keep moving in the same direction and at the same speed if the forces acting on it are balanced.

## What happens when two equal forces collide?

Newton’s third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

## When two forces are there is a change in position or motion?

When two forces are equal and act on an object in opposite directions, they balance each other out. When this happens, there is no change in an object’s motion. the same direction, the two forces are added together. Adding the forces together cause a change in an object’s motion, speed, or direction.

## What causes the rolling ball to stop when there is no one to push it continuously answer?

When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction.

## When a force acting on a body and moves it is called?

A push or pull on a body is called force. … Pushing means exerting force on someone or something in order to move them away from us. Pulling means exerting force on someone or something in order to move them towards us.

## What is the resultant force acting on a body when two equal and opposite forces act on it?

When two forces act on a body from two opposite directions and their magnitudes are equal,the forces cancel out each other’s effects,thus produ mcing no change in the body.So,the resultant force is zero.

## Can action and reaction forces cancel each other?

exerted by two objects on each other are often called an action- reaction force pair. Either force can be considered the action force or the reaction force. … However, action and reaction force pairs don’t cancel because they act on different objects. Forces can cancel only if they act on the same object.
