Question

7.
The distance-time graph of a body is a straight line
parallel to the time axis. What information does the
graph convey regarding the motion of the body?
6. Which physical quantity can be calculated by finding the
slope of a distance-time graph?
Area under the velocity-time graph line is 40 m. What
physical quantity does this area represent?
8. How can you calculate acceleration from a v-t graph?
9. State differences between distance and displacement.
10. State two differences between speed and velocity.
11. A car moving along a circular path of radius 140 m,
completes one round in 20 s. What is (i) the speed of the
car (ii) the displacement of the car?
​

Answer 1

6. Slope gives the speed,
7. Distance (s)
8. Slope (v=u+at)
9. Distance
It is the actual path followed by a body between 2 points.
It is scalar quantity.
It can never be negative or zero,
Not a unique path.

Displacement
It is the shortest distance between two points
It is vector quantity
It can be negative,zero
It a unique path
10. Speed is distance per unit time
Velocity is displacement per unit time
