Elastic collision
A collision in which kinetic energy of the system is conserved is called elastic collision.
In the ideal case when no kinetic energy is lost, the collision is said to be perfectly elastic.
Example
when a hard ball is dropped onto a marble floor, it rebounds to very nearly the initial height. It loses negligible amount of energy in collision with the floor.
Inelastic collision
A collision in which kinetic energy of the system is not conserved , is called the inelastic collision.
Example
When tow tennis balls collide the then after collision , they rebound with velocities less than the velocities before, the inspect. During this process a portion of K.E is lost,partly due to friction as molecules in

Energy
i read in my books word of energy derive from energeia.
we defined as about energy The ability of a body to do work is called energy.
There are to basic forms of energy.
Kinetic and Potential energy
What is kinetic energy
we also discus about energy and kinetic energy is other form of energy.kinetic word is derived from Greek word kinesis meaning motion.
The possessed by a body due to its motion is called kinetic energy.
it is given by the formula.
it is given by the formula.

Momentum:
Moving object possesses a quality virtue of which it experts a force on anything that tries to stop it.The faster the object is traveling, the harder to stop it.If two object moves with same velocity, then it is difficult to stop the massive of the two.
By Newton, this quality of moving body was called the quantity of motion of the body. this is now called linear momentum of body.
By Newton, this quality of moving body was called the quantity of motion of the body. this is now called linear momentum of body.
Definition of momentum:
the product of mass and velocity of body is called linear momentum.

The property of an object tending to maintain the state of rest or state of uniform motion is referred to as the object's inertia.
The more is the inertia, the stronger is this tendency in the presence of a force.
thus,
"The mass of the object is a quantitative measure of its inertia".
we can says Newtons first law of motion called law of inertia.newtons first law is that
A body at rest will remain at rest, and a body moving uniform velocity will continue to do so, unless acted on by some unbalanced external force.This is also known as law of inertia.

The branch of science which deals with the study of matter and energy and the relationship between them is called physics.
we can also called about what is physics The study of physics involves investigation of such things as the laws of motion,the structure of space and time,the nature and type of forces that hold different materials
together, the interaction between different particles, the interaction of electromagnetic radiation with matter and so on.
