CBSE IX Physics Motion
1. A car is travelling along the road at 8 m/s .It accelerates at 1m/s2 for a distance of 18m. How fast is it travelling?
2.The distance between mumbai to delhi is 1384. A train starts from Mumbai at 4pm and reaches delhi at 10 am the next day.What is its average speed?
3.State the 3 equations of motion. Which equation describes velocity-time relation and position -time relation?
4. A cheetah starts from rest and accelerates at 2 m/s2 for 10 seconds. Calculate the final velocity and the distance travelled?
CBSE X Physics Sources of Energy
AN OBJECT MOVES WITH ACCELERATION "ALPHA" FOR SOME TIME AND "BETA"FOR ANOTHER TIME.THE OBJECT STARTS FROM REST AND IN ANOTHER HALF FINALLY COMES TO REST .THE EVENT TAKES PLACE IN TIME "t".FIND THE MAXIMUM VELOCITH ATTAIED AND TOTAL DISTANCE TRAVELLED BY THE OBJECT?
CBSE XI Science Physics Motion in a Straight Line
the position of the particle along x-axis varies with time as
x = 4t2 - 6t + 1, then:
(a) What is the velocity at t = 0?
(b) When does velocity become zero?
