Answer 2

Answer:

1.Periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave.

2.The massive object is affectionately referred to as the pendulum bob. When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position. The motion is regular and repeating, an example of periodic motion.

3.In a crowded road, moving through different traffic conditions, a bus travels at different speeds at different points of time.

So, this is an example of non-uniform motion.

4. A spinning top, or simply a top, is a toy with a squat body and a sharp point at the bottom, designed to be spun on its vertical axis, balancing on the tip due to the gyroscopic effect

5.A stone is dropped form certain height which can reach the ground in `5s`. If the stone is stopped after `3s` of its fall and then allowed to fall again. Find the time taken (in second) by the stone to reach the ground for the remaining distance
