## What is the relationship between balanced forces and motion?

When the motion of an object changes, the forces are unbalanced. Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion.

## What is the relationship between unbalanced forces and second law of motion?

Newton’s Second Law of Motion is concerned with the effect that unbalanced forces have on motion. An unbalanced force acting on an object causes it to accelerate. The more mass the object has, the more inclined it is to resist any change to its motion. For example, if you apply the same unbalanced force to a mass of.

**What is the relationship between net force and Newton’s first law?**

Newton’s first law says that if the net force on an object is zero ( Σ F = 0 \Sigma F=0 ΣF=0\Sigma, F, equals, 0), then that object will have zero acceleration. That doesn’t necessarily mean the object is at rest, but it means that the velocity is constant.

**Does Newton’s first law deal with balanced forces?**

This means that for an inertial reference frame, Newton’s first law is valid. Equilibrium is achieved when the forces on a system are balanced. A net force of zero means that an object is either at rest or moving with constant velocity; that is, it is not accelerating.

### What is balanced force give example?

When two forces are the same strength but act in opposite direction, they are called balanced forces. Again, tug-of-war is a perfect example. If the people on each side of the rope are pulling with the same strength, but in the opposite direction, the forces are balanced. The result is no motion.

### What kind of relationship is Newton’s second law?

Newton’s second law says that the acceleration and net external force are directly proportional, and there is an inversely proportional relationship between acceleration and mass. Also, force and acceleration are in the same direction.

**What are some examples of the second law of motion?**

Newton’s Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Riding your bicycle is a good example of this law of motion at work. Your bicycle is the mass. Your leg muscles pushing pushing on the pedals of your bicycle is the force.

**What is inertia depend on?**

Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed.

#### What happens if there is no inertia?

If there is no inertia the body will continuously keep moving or if it is at rest it will continue to be at rest. Inertia is the measure of mass. If there is no inertia then there will be no mass. The particles will have infinite acceleration.

Newton’s laws of motion imply the relationship between an object’s motion and the forces acting on it. In the first law, we come to understand that an object will not change its motion unless a force acts on it. The second law states that the force on an object is equal to its mass times its acceleration. And, finally, the third law states that

**When does an object in motion have a balanced force?**

Once the box hits the water, the forces are balanced (50 N down and 50 N up). However, an object in motion (such as the box) will continue in motion at the same speed and in the same direction.

**How are unbalanced forces different from balanced forces?**

Balanced and Unbalanced Forces. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

## How does Newton’s first law affect the motion of a system?

Again looking at Figure 1 (a), the force the child in the wagon exerts to hang onto the wagon is an internal force between elements of the system of interest. Only external forces affect the motion of a system, according to Newton’s first law. (The internal forces actually cancel, as we shall see in the next section.)
