## What happens when two equal forces act in opposite direction?

Equal forces acting in opposite directions are called balanced forces. Balanced forces actingon an object will not change the object’s motion. When you add equal forces inopposite direction, the net force is zero.

### Is the tension in the rope the same on both sides of the pulley?

Pulley: A pulley serves to change the direction of a tension force, and may also (in the case of multiple-pulley systems) change its magnitude. The tension of an “ideal cord” that runs through an “ideal pulley” is the same on both sides of the pulley (and at all points along the cord).

#### Is tension equal and opposite?

Each one is applying a tension force on the rope. Those two forces are equal in magnitude, and opposite in sense (direction).

**What does it mean when 2 opposing forces are equal?**

Overview. The net force acting on an object is the combination of all of the individual forces acting on it. If the opposing forces are equal, or balanced, the net force is zero, as it is for the book.

**When two forces applied on an object are equal and opposite?**

Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object’s motion.

## When two force applied on an object are equal and opposite then these forces?

Equivalent forces are those forces which are equal in magnitude and also in the same direction.

### Can one rope have two tensions?

This is equivalent of having two ropes: one from the ceiling to the body, and one from the body downwards. This can be repeated with multiple bodies. Thus, the tension in the highest rope will be the largest, followed by each successive block. However, each rope section will have uniform tension.

#### Why is tension the same on both sides of a rope?

Explanation: The rope experiences the same pulling force on both sides, and therefore it is in a state of static equilibrium (i.e. it is at rest consequently has a net force of zero). Newton’s third law states that every force occurs as a member of an action/reaction pair of forces.

**Is tension equal throughout a rope?**

The tension in the rope is constant if its force does not have to be used to accelerate anything else, including itself. Therefore, if it has negligible mass and is held taut between two points, the tension will be considered constant throughout.

**How do you find tension in a rope?**

When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.

## What happens when two forces are equal?

When two forces act in the same direction, they add together. Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object’s motion. When you add equal forces in opposite direction, the net force is zero.

### Are the two forces equal in magnitude Why?

According to Newton’s third law, the forces on the two objects are equal in magnitude. While the forces are equal in magnitude and opposite in direction, the accelerations of the objects are not necessarily equal in magnitude.

#### What is the tension force in the rope?

This tells us that the pulling force exerted by each person on the rope is 65N, and consequently by NIII, the rope exerts an equal but opposite tension force of 65N on each person. This is an action reaction pair. Therefore: The tension force in the rope, given by → F Ron1 and → F Ron2, is therefore 65N.

**What is the acceleration of a rope with two opposite forces?**

If you have two, equal but opposite forces at each end of the string, there will be no acceleration. Think about the game of tug of war. You have persons at each end of the rope pulling with equal but opposite forces F so there is no acceleration of the rope. The sum of the external forces on the rope is zero.

**Why do we use pulleys instead of ropes to pull blocks?**

In case a man is pulling the block with a rope/string, the rope experiences tension in one direction from the pull and tension in the other direction from the reactive force of the block. The dynamics of a single rope is quite simple and easy as it transmits the applied force. But when pulleys are used instead of ropes then the complications arise.

## Is there acceleration when there are two forces acting on one string?

No. If you have two, equal but opposite forces at each end of the string, there will be no acceleration. Think about the game of tug of war. You have persons at each end of the rope pulling with equal but opposite forces F so there is no acceleration of the rope.
