What if force is negative?

It means that the force is going to the opposite direction. A ‘negative’ force is one that is acting in the direction opposite to what you decide to be the positive direction (Usually, upward is +ve, downward is -ve). If the object is accelerating, then the situation is different.

What is negative force and positive force?

Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work. If the force has a component in the direction opposite to the displacement, the force does negative work.

Is the force of attraction positive or negative?

When the charges have opposite sign, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).

Can you have a negative resultant force?

A resultant force can be calculated by taking forces that act along the same line and add them together. If the forces are in the same direction as each other, then they have a positive value. If one force is acting in the opposite direction to another one of the forces is given a negative value.

What is positive force?

When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.

Can force be positive when?

Complete answer: Positive work is done by a force when the displacement of the body is in the direction of the force applied whereas negative work is done by the force when the direction of the displacement of the body is opposite to the direction of the force.

Which is positive force?

What is the difference between positive and negative work give an example of each?

When the displacement of the body the in the direction of the force then the work done is positive. For example :- a man pushing a car in a straight path. When the displacement is in a direction opposite to the direction of the force then the work done is said to be negative. For example :- work done by the friction.

Why is attraction force negative?

That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational …

Can a Newton force be negative?

The unit of force is Newton. Force can be negative or positive. The magnitude of the force is always a positive (or zero) quantity. Vector quantity.

What is negative work example?

Negative work is performed if the displacement is opposite to the direction of the Force applied. Example: Work was done the gravity on a rocket going perpendicular upwards.

What is meant by positive and negative work give one example each?

Example: When an object moves on horizontal surface, force and displacement acts in same direction. So, work done is positive. NEGATIVE WORK: The work done is said to be negative work when force and displacement are in opposite direction.
