speed, velocity, acceleration and stuffs
Letts's see first what speed is . Let’s say a girl throws a ball to rightwards now irrespective of direction the ball rolls to right with 50 ms-¹. This
50 ms-¹ in any direction is called speed of object. Now here comes another question how velocity is different from speed. Basically, velocity is noting but speed with direction. Let’s say a ball is thrown towards left with speed 50 ms-¹. Now, this speed magnitude with specified direction is called velocity of object.

Hoorah!
Now here comes acceleration acceleration is rate of change of velocity with respect to time . Lets say the ball thrown in the previous example is in direction of rightwards with magnitude 50 ms-¹. Now lets say the ball is hit by a external force lets say bat but in same direction its speed changes to 80 ms-¹. Now, the time in which this takes place is 3 seconds. So the acceleration will be dv/dt. is nothing but v2-v1/t2-t1, which comes out to be 10 ms-².
So we are now clear with the concept of speed velocity and acceleration. Ah the stuff it’s already above speed, velocity and acceleration.Hoorah!
