Question

1)define motion What are the diffrent types of motion
2) Diffrentiate between a Uniform and Non-uniform motion.
3 )show the shape of the distance time graph for the motion in the following case:
a) A car moving with a constant speed
b A car parked on a roadside
4)What is a simple pendulum? How does it work?
5)A simple pendulum takes 32 Second to complete 20 osicilation?What is the time period of the speed of the train pendulum?
6) The distance between to stations 240 km A train takes 4 hour cover this distance, that calculate the speed of train?​

Answer 1

1. The objects which change their positions with time are said to be in motion.
2. NON-UNIFORM MOTION

If the speed of an object moving along a straight line keeps changing, its motion is said to be non - uniform .

UNIFORM MOTION

On the other hand, an object moving along a straight line with a constant speed is said to be in uniform motion.

6. speed =distance/time

=240/4

= 60 km /hr

hope this helps to you

Answer 2

Explanation:

(1)In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control. (2)In uniform motion, a body moves with a constant speed such as the Motion of earth around the sun. While in non-uniform motion a body moves with a variable speed such as a Horse running in the race. (3)(i) A car moving with a constant speed covers equal distance in equal intervals of time. It will be a uniform motion. Distance-time graph will be as below: (ii) A car parked on a road there is no change in the distance with the time.(4)A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. ... with being the natural frequency of the motion.(5) The time taken to complete one oscillation is known as the time period of the pendulum. Given: - 20 oscillations taking 32s to complete. Therefore 1.6s is the time period of the pendulum.(6)The distance between the two stations is 240 km. A train takes 4 hours to cover this distance. Calculate the speed of the train. Therefore the speed of the train is 60km/hr.
