First Law Of Motion Formula

Newton s first law of motion is also referred to as the law of inertia.

First law of motion formula. Newton s first law of motion. In its most general form it states the rate of change of momentum p p t m v t of an object equals the force f f x t v t t acting on it 13. Newton s first law of motion states that 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 below is the formula to find force based on law. Similarly if the object is at rest it will remain at rest unless an unbalanced force acts upon it.

The focus of lesson 1 is newton s first law of motion sometimes referred to as the law of inertia. Velocity is a vector quantity which expresses both the object s speed and the direction of its motion. Newton s first law of motion is often stated as. The first law states that if the net force the vector sum of all forces acting on an object is zero then the velocity of the object is constant.

It requires some force from the outside to cause such a change. Newton s first law is also known as the law of inertia. Some sample problems that illustrates the first and second laws of motion are shown below. This property of massive bodies to resist changes in their state of motion is called inertia.

The first law of motion implies that things cannot start stop or change direction all by themselves. Therefore the statement that the object s velocity is constant is a statement that both its speed and the direction of its motion are constant. Motion of an object that is not accelerated moving at a constant speed and in a straight line can be found using the formula. Newton s first law is also known as the law of inertia inertia is the inherent ability of a body because of which it has a tendency to maintain its original state and opposes any change in its state.

It takes force to change the original state as well as the motion of an object. Newton s first law of motion. V is the rate of motion velocity t is the time. 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.

To learn how to derive the equation of motion for a first second third equation of motion visit byju s. The first general equation of motion developed was newton s second law of motion. Equations of motion are derived using the algebraic method graphical method and calculus method. Newton s first law of motion states that an object in motion tends to stay in motion unless an external force acts upon it.
