Question

(a) Identify the nature of motion of the body.
(b) Find the acceleration of the body.
(c) Draw the shape of distance-time graph for this type of motion. (1 + 2 + 2)
7. Draw the shape of the distance-time graph for uniform and non-uniform motion of
object. A bus of starting from rest moves with uniform acceleration of 0.1 ms- for 2
minutes. Find
(a) the speed acquired.
(b) the distance travelled. (3)
8. Define uniform acceleration. What is the acceleration of a body moving with uniform
velocity?
(3)
9. A bus accelerates uniformly from 54 km/h to 72 km/h in 10 seconds Calculate
(i) acceleration in m/s2
(ii) distance covered by the bus in metres during this interval.
(3)
10. A car moves with a speed of 30 km/h- for half an hour, 25 km/h- for one hour and
40 km/h- for two hours. Calculate the average speed of the car. (2)
11. (a) Differentiate between uniform linear and uniform circular motion.
(b) Write any four examples of uniform circular motion.
(c) Is uniform circular motion accelerated motion? (2 + 2 + 1)​

Answer 1

Explanation:

when the body change its position with time then it is said to be in motion

Answer 2

Answer:

Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.
