Direction vs Velocity Lesson

Speed & Velocity
Dewese 9th Acc

The distance an object travels per unit of time

​​Speed

the distance covered by an object per unit time.

Velocity

​Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.

​The Difference between Speed & Velocity

the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs. The average velocity can be positive or negative depending upon the sign of the displacement..

1. ​ the rate of change in speed as the body moves away from its initial point

2. It is also known as negative acceleration as it decreases the velocity of the body to zero. It is the ratio of the difference between the final velocity and initial velocity to the total time taken
