Speed And Velocity

Speed

The distance covered by an object divided by the time taken by the object to cover that distance is called the speed of that object.

Speed
Speed

It is a scalar quantity. Its SI unit is m/s and dimensional formula is [M⁰LT⁻¹].

Uniform Speed

If an object covers equal distance in equal interval of time, then its speed is uniform.

Non-Uniform Speed

If the object covers equal distances in unequal interval of time, then its speed is non uniform.

Velocity

The rate of change of position of an object with time is called the velocity of that object.

Velocity
Velocity

Velocity is a vector quantity. Its SI unit is m/s and dimensional formula is [M⁰LT⁻¹].

Uniform Velocity

If an object have equal displacement in equal interval of time, It means that it is moving with uniform velocity.

Non-Uniform Velocity

If an object is moving with a non-uniform velocity, then it will have unequal displacements in equal interval of times.
