Second Law Of Motion Formula And Example

Defining newton s second law of motion newton s second law states that the acceleration of an object depends upon two variables the net force acting on the object and the mass of the object.

Second law of motion formula and example.

It gives the quantitative definition of force. Newton s laws of motion are three physical laws that together laid the foundation for classical mechanics they describe the relationship between a body and the forces acting upon it and its motion in response to those forces. According to newton s first law of motion if no net force is acting on a body at rest then the body remains at rest or if the body is moving will continue to move. What some people don t know however is that newton s second law of motion is actually written out in a very simple equation that allows scientists to calculate the amount of force needed to move an object of a certain weight at a certain rate of acceleration.

The second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Newton s second law is a quantitative description of the changes that a force can produce on the motion of a body. A softball has a mass of 1 5 kg and hits the catcher s glove with a force of 30 n. In the second law of newton known as the fundamental principle of dynamics the scientist states that the larger the mass of an object the more force will be required to accelerate it.

F ma where f force m mass and a acceleration. Newton s second law of motion is related with the first law of motion. Newton s second law of motion can be formally stated as follows. That is the acceleration of the object is directly proportional to the net force acting on it and inversely proportional to that of the object.

Before understanding the equation of newton s second law of motion which deals with force mass and acceleration of an object let. Refer the newton 2nd law of motion problems with solutions. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. Mathematically it describes the causes and effects of force and changes in motion of an object.

The formula is written out as force being equal to the mass times the acceleration. The momentum of a body is equal to the product of its mass and its velocity. Newton s second law of motion states that the rate of change of momentum of a body is directly proportional to the applied force. The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force in the same direction as the net force and inversely proportional to the mass of the object.

Substituting the values in the above given formula net force f net 15 x 10 150 n therefore the value of net force 150 n.
