# What is the second law of force?

## What is the second law of force?

Newton’s second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.

## What does Newton’s second law say about force?

That situation is described by Newton’s Second Law of Motion. According to NASA, this law states, “Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration.” This is written in mathematical form as F = ma.

What is the formula for force using the 2nd law?

Newton’s second law of motion is F = ma, or force is equal to mass times acceleration.

What does the 2nd Law of Motion State?

The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

### What force is the result of unbalanced forces?

When two forces acting on an object are not equal in size, we say that they are unbalanced forces. The overall force acting on the object is called the resultant force . If the forces are balanced, the resultant force is zero.

### What is Newton’s second law in simple terms?

Newton’s Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Newton’s Second Law also says that the greater the mass of the object being accelerated, the greater the amount of force needed to accelerate the object.

What is Newton’s second law of motion class 11?

Newton’s second law of motion can be expressed as the rate of change of momentum of an object is directly proportional to the applied force on the object and the change in momentum takes place in the direction of the applied force.

Which law is fundamental law of motion Why?

Newton’s second is known as fundamental law Because it gives an idea about how the motion of a body change and how changes in motion is related to the mass of the body and the force acting on the body.
