Accelearated Motion

Description:

When a particle is in motion, its velocity keeps on changing. The velocity can change uniformly (known as uniform variation of velocity) or non-uniformly (known as non-uniform variation of velocity).

The change in velocity with respect to time is known as acceleration i.e. acceleration is the rate of change of velocity.

Acceleration is given by −

Acceleration = Change in velocity/Time taken

∴ a = Δv/Δt = dv/dt

Types of acceleration

Uniform acceleration

When the rate of change of velocity is constant, then acceleration is said to be uniform acceleration.

Non - uniform acceleration

When the rate of change of velocity is not constant, then acceleration is said to be non - uniform acceleration.
