When is a body said to be in motion?
The speed of a car is 72 km h-1. Express it in m s-1.
A train takes 2 h to reach station B from station A, and then 3 h to return from station B to station A. The distance between the two stations is 200 km. Find:
The average speed,
The average velocity of the train.
A car moving on a straight path covers a distance of 1 km due east in 100 s. What is velocity of the car?
Figure shows the displacement of a body at different times .
Calculate the average velocity during the time interval 5 s to 9 s ,
[Hint : From 5 s to 9 s , displacement = 7 m - 3m = 4m]
The velocity-time graph of a moving body is given below in Figure
Total displacement.
