Velocity is a rate of change of the position of an object within a certain time range. It is a vector quantity, measured with respect to time. There are two types of velocities: angular velocity and linear velocity.
What is a Linear Velocity?
Linear velocity is the rate of change of the position of an object that is travelling along a straight path. Any object that moves has a linear velocity.
Angular Velocity to Linear Velocity:
Anything that moves or turns in the circular direction has both linear velocity and angular velocity. The angular velocity is the ratio of the angle traversed to the amount of time it takes to traverse that angle.
Angular velocity gives an expression of angular displacement over time and it can be expressed in radians or degrees. To calculate the linear velocity from angular velocity, we can apply the formula.
Constant Linear Velocity:
When a body moves with constant speed without changing its direction, it is said to be moving with the constant linear velocity. Linear velocity indicates the direction is not changed, and constant shows that the magnitude is not changed.
Linear Velocity Formula:
The linear velocity depends on the distance travelled by an object with respect to time taken. The linear equation or the linear velocity formula is given by,
V = Linear Velocity,
d = Distance,
t = Time taken to cover the distance.
