Concept:
Power is defined as the time rate at which work is done or energy is transferred. Power, like work and energy, is a scalar quantity.
Momentum (p): The product of mass and velocity is called momentum.
Impulse: When a large force works on a body for a very small time interval, it is called impulsive force.
\(\vec I = \mathop \smallint \limits_{{t_1}}^{{t_2}} \vec F \cdot dt\)
Where, I = impulse, F = force and dt = very small time interval
Potential energy is defined as the energy stored due to change in position relative to others, stresses within itself, or many factors.
Acceleration: The rate of change of velocity is called acceleration.
Weight: The weight (w) of an object is the force of gravity on the object and may be defined as the mass (m) times the acceleration of gravity (g).
Work done: Work is said to be done when a force applied on the body displaces the body through a certain distance in the direction of a force.
Kinetic energy (K.E): The energy possessed by a body by the virtue of its motion is called kinetic energy.
