How to calculate the work done by force?
When the force moves an object to the distance t is called work done. It is the most common term used in physics or...
Inelastic Collision
During a collision between two bodies if there is a loss of kinetic energy, then the collision is said to be an inelastic collision.
In...
Collisions
Collision between two or more particles is the interaction for a short interval of time in which they apply relatively strong forces on each...
Conservative Forces
Forces are said to be conservative in nature if work done against the forces gets conversed in the body in form of potential energy....
Power
Power is defined as the time rate at which work is done or energy is transferred.
The average power of a force is defined as...
Conservation of Mechanical Energy
The total mechanical energy of a system is conserved if the forces, doing work on it, are conservative.
Suppose that a body undergoes displacement Δx...
Potential Energy of a spring
Energy possessed by the spring by virtue of compression or expansion against elastic force in the spring is known as elastic potential energy or...
Potential Energy
Potential energy is the ‘stored energy’ by virtue of the position or configuration of a body. The body left to itself releases this stored...
Kinetic Energy
If an object of mass m has velocity v, its kinetic energy K is
Kinetic energy is a scalar quantity. The kinetic energy of an...
Work-Energy Theorem
The work-energy theorem states that the change in kinetic energy of a body is the work done by the net force on the body.
Kf...
