The displacement Vs time graph is given below which of the following conclusions is correct:
Four velocity time graphs (Namely I , II , III , IV ) are shown in the figure. In which case is the acceleration uniform and positive
A body is moving with velocity 30m/s towards east. After 10 seconds its velocity becomes 40m/s towards north. The average acceleration of the body is
A car moving with 72 km/hr comes to rest in 5 second its acceleration is: (in m/s2)
Rate of change of velocity with time.
Formula-
a=change in velocity/change in time
Tips for Acceleration-
It is a vector quantity
Dimension =
S.I unit =
Eg. A car starting from rest accelerates uniformly to a speed of 75 m/s in 12 seconds. What is the car's acceleration ?
Types for Acceleration
based on the nature of acceleration
There are three types of acceleration
Positive Acceleration-
If the final velocity is greater than the initial velocity. For: V2 > V1
E.g.- When a bus speeds up.
Negative Acceleration-
When the final velocity is less than the initial velocity. For:
Example- When a bus slows down.
Zero Acceleration-
When the final velocity is equal to the initial velocity. For:
E.g.- When a bus is moving with uniform velocity.
