Why Newton’s second law is the real law of motion

In my one of earlier articles on Newton’s law, I have discussed about the Newton’s second law. We all are also aware about the Newton’s first law which mainly states that if an object is at rest will remain at … Continue reading

Difference between force and torque

Students often asked me what is the difference between force and torque? We might be aware about these terms that is force and torque. Let us understand the concept of force. Force according to a layman is an effort to … Continue reading

Difference between conservative and non conservative forces

We all are aware about the concept of force, if not then force may be defined as any push or pull that can change the state of rest of an object or can change the velocity of the moving object … Continue reading

3 examples of Inertia of direction

As we have already discussed that the inertia of direction is defined as the inability of a body or object to change its direction of motion by itself. That is external force is required to change its direction of motion. … Continue reading

impulse force and its applications

Impulsive Forces: The force which act on a body for a short time are known as Impulsive forces. For eg. Hitting a ball with bat fining a gun etc. An Impulsive force doe snot remain constant but changes, firstly from … Continue reading

Derive relation F = ma from Newton 2nd Law of Motion

Let us derive the relation of force F = ma from Newton’s second law: According to the Newton’s 2nd Law of motion, the rate of change of linear momentum of a body is directly proportional to the applied external force … Continue reading

Types of Inertia

There are basically three types of Inertia-: (a) Inertia of Rest: The inability of a body to change by itself its state of rest is known as Inertia of Rest. Examples: (i) Person sitting in a car falls backwards, when … Continue reading

What are Newton’s Laws of motion

The following are the Newton’s laws of motion : Newton’s I Law: A body continues to in its state of rest or of uniform motion along a straight line unless an external force is applied on it. Show that Newton’s … Continue reading

Force, inertia and linear momentum

Force: The pull or push which change or tends to change the state of rest or of uniform motion or direction of motion of an object is called Force. The units and dimension of force:   We know that                                  F … Continue reading
