# CBSE Class 11-science Physics Displacement And Velocity

## Videos

- •A jogger runs in a straight line with –an average velocity of 5 m/s for 4 min. –an average velocity of 4 m/s for 3 min. •What is the total displacement? •What is the average velocity during this time?
- what is numerical ratio between velocity and speed
- If a man walk at a speed of 10 km/h, then find the distance traveled by the man in 5 hours?
- the velocity of a particle moving along x axis is given by v=x2 - x, where x is metre and v in m/s what is its position when velocity is minimum
- 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?
- the motion by body is described by the equation v=at square find the distance travelled by the body in the first 2second
- a man travels on a straight road from his home to the bank with a uniform speed of 18km/h for 10s and then travels with a uniform speed of 36 km/h for next 20 s on a straight road from bank to market. the average speed of the man for the whole journey is
- Derive an expression for average velocity and instantaneous velocity for the motion of an object in x-y plane.
- Particles moves a certain distance In a staright line as follows first 1/4th at V° next 1/2th at 2v2 last 1/4 th at v0 find avg speed
- from A to B speed is v⁰. From B to C during first half speed is v1 and during last half speed is v2 . Find Average Speed From A to C
