4.Sketch the graph for a) uniform motion b) non uniform motion c) uniform acceleration d) uniform deceleration and nonuniform acceleration. Write short notes for each graph.
Answers
uniform motion:
This type of motion is defined as themotion 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.
Non-uniform motion:
The distance-time graph of the non-uniform motion is a curved line. Non-Uniform motion is also known as accelerated motion. More examples of non-uniform motion are: Oscillation of pendulum, the motion of a train, a person jogging in the park
uniform acceleration:
If an object's speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn't have uniform acceleration.
retardation:
Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be
