What is third law of motion. Give examples
) Draw speed - time graph for non-uniform motion
Answers
Explanation:
Uniform Motion:
Definition: This type of motion is defined as the motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.
Uniform Motion
If a body is involved in rectilinear motion and the motion is consistent, then the acceleration of the body must be zero.
Example of Uniform Motion:
If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant in every second.
Movement of blades of a ceiling fan.
Non Uniform Motion:
Definition: This type of motion is defined as the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.
Non Uniform Motion
If a body is involved in rectilinear motion, and if the motion is not consistent, then the acceleration of the body must be non-zero
Example of Non Uniform Motion:
If a car covers 10 meters in first two seconds, and 15 meters in next two seconds.
The motion of a train.
Now, people usually get confused between uniform motion and uniform acceleration. In the later phenomena, the object is having a constant acceleration in rectilinear motion, which means the object has different speed in every second, which clearly defines that motion is changing
