# What is required for a force to do work on an object?

## What is required for a force to do work on an object?

In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. For the special case of a constant force, the work may be calculated by multiplying the distance times the component of force which acts in the direction of motion.

## What two things can a force do to an object?

Forces can cause objects to accelerate , decelerate , stop , start moving , change direction , change shape , or even turn .

## What is required for a force?

Well, What is the requirement for force to come into play? An interaction of one object with another object results in a force between the two objects . In other words, A force will arise due to interaction between two objects. If there is no interaction between two objects , no force can show it’s effect.

## What are the three essential conditions for work done by a force acting on an object?

1) Force must be applied on body. 3)The displacement of body should be in direction of force.

## What happens when two forces act on an object?

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. If two forces of equal strength act on an object in opposite directions, the forces will cancel, resulting in a net force of zero and no movement.

## What is a force what can force do?

WHAT IS FORCE? A force is a push or a pull. Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a distance (such as a magnet or gravity).

## What happen when two forces act in the same direction?

Forces Acting in the Same Direction If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone.

## What are the effects of force on an object?

A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate. When there’s the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction.

## What are the two conditions for work done?

The two conditions are: (i) Application of-force on the body. (ii) Displacement of the body in the direction of force.

## What are the two conditions need to be satisfied for work to be done?

Two conditions need to be satisfied for work to be done: Force should act on the object. Object must be displaced.

## What happens when 2 forces act in the same direction Class 8?

When two forces act on an object in the same direction, they add up in order to give a resultant large force. The magnitude of the forces also add up to produce a resultant that is equal to the sum of the two forces acting in the same direction.

## What will happen if two forces will act in opposite directions on an object?

If two forces of equal strength act on an object in opposite directions, the forces will cancel, resulting in a net force of zero and no movement. equal to the sum of the two forces.
