Question

moving on a crowded road with a number of traffic red snow
motion
Displacement of a body can be positive or zero, but never negative.
Angular displacement is measured in radians.
10. A freely falling body is uniformly accelerated.
Define acceleration and state its Sl unit. For motion along a straight line, when do we
consider the acceleration to be positive (1) negative? Give an example of a body in
uniform acceleration.
2. A car travels at 54 kmh for first 20 s.36 km/h for next 30 s and finally 18 km/h for ne
s. Find its average speed.
3. Define acceleration and give its SI unit. When is acceleration of a body negative? Gia
two examples of situations in which acceleration of the body is negative.
Distinguish between uniform motion and non, uniform motion. Is uniformly accelerate
otion uniform motion? Give one example each of uniform and non-uniform motion.
5. The speedometer readings of a car are shown below. Find the acceleration of the ca
displacement
