# What happens if there is no resultant force?

## What happens if there is no resultant force?

If there is no resultant force then a system is said to be in equilibrium . If the resultant force is not zero, a moving object will speed up or slow down – depending on the direction of the resultant force: it will speed up if the resultant force is in the same direction as the object is moving.

What happens if the resultant force is not zero on an object?

Most moving objects are acted upon by a driving force and retarding (often frictional) forces acting in the opposite direction to the motion. When the forces do not add to zero (there is a non-zero resultant force), the object will either speed up, slow down or change direction.

Why is resultant force important?

The resultant force is firstly a key-word that any examiner will notice and so it will benefit your chance of getting the marks straight away. It helps us describe whether the forces are balanced or whether there is an overall force in a particular direction.

### What is the effect of a resultant force on an object?

The resultant force is essential to change the velocity of an object. If the resultant force is zero the forces on the object are balanced. If the resultant force acting on the object is ‘zero’ then: the object will remain stationary. In such a case the object will move at a steady speed in a straight line.

Where is the resultant force equal to zero?

According to Newton’s First Law of motion, an object remains in the same state of motion unless a resultant force acts on it. If the resultant force on an object is zero, this means: a moving object continues to move at the same velocity (at the same speed and in the same direction)

What is the formula of resultant force?

Resultant force F = 3 N + 2 N = 5 N to the right. The resultant force is 5 N to the right. Two forces that act in opposite directions produce a resultant force that is smaller than either individual force. To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force.

## What do we call a push and pull on an object?

A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.

What happens when two forces are balanced on an object?

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a moving object continues to move at the same speed and in the same direction.

Can the resultant of two forces be zero?

All forces acting on an object add to zero: the resultant force is zero.

### What happens when there is no resultant force?

If no resultant force acts on an object, it will not accelerate; it will remain at rest or it will continue to move at constant speed. If an object is at rest or is moving at a constant speed in a straight line ,we can say that there is no resultant force on it.

When are the resultant forces of acceleration zero?

If an object is traveling at constant speed and still moving in the same direction, it is not experiencing acceleration, and thus the resultant forces acting on it are zero. This is exactly the same for an object at rest, except that its speed happens to be zero.

When does an object remain in the same state of motion?

According to Newton’s First Law of motion, an object remains in the same state of motion unless a resultant force acts on it. If the resultant force on an object is zero, this means: a stationary object stays stationary. a moving object continues to move at the same velocity (at the same speed and in the same direction)

## What happens when you remove a force from an object?

When a force is applied the velocity of the object changes from 0 to some velocity V (and it keeps increasing as long as the force is present). This change in velocity is termed as acceleration. Now if you remove the force, the object will move with the constant velocity V provided no other force is acting on it.
