### Equations of Motion

The relationship among different parameter like displacement velocity, acceleration can be derived using the concept of average acceleration and concept of average acceleration and instantaneous acceleration.

When acceleration is constant, a distinction between average acceleration and instantaneous acceleration loses its meaning, so we can write



where  is the velocity at t = 0 and  is the velocity at some time t.

So,

.................. (2)

This is the first useful equation of motion.

Similarly for displacement

.................. (3)

in which  is the position of the particle at t0 and  is the average velocity between t0 and later time t. If at t0 and t the velocity of particle is

This is the second important equation of motion.

Now from equation (2), square both side of this equation we get

This is another important equation of motion.
