Motion

We are familiar with friction in various ways in our daily lives. From Newton’s first law of motion we know that if no force acts…

Example 1: A force of 2000 N acts on a body of mass 20 kg for a time of 0.1 s. What is the change of…

Whenever a force acts on one body, at that time an equal and opposite force acts on some other body. This matter is generally stated…

Example 1: What is the force to be applied to a mass of 50 kg to produce an acceleration of 4 ms-2 ? Solution Here,…

Newton’s first law gives qualitative definition of force. Newton’s second law gives the equation for the measurement of force. From Newton’s second law we know…

Here explain some common effect of force on motion:   A force can cause a stationary object to start moving. What happens when a stationary football…

The physical quantity which is produced by the combination of mass and velocity of a moving body is the momentum. Momentum depends on the mass…

When two or more forces acting on an object produce zero resultant force, i.e. the object has no acceleration; we say that the forces are…

Though we observe different kinds of force in nature, fundamental force are of four types. Rest of them is some forms of these fundamental forces.…

We have a general concept about force from our daily life experiences. When we pull or push a body, then we say a force is…
