Difference between Uniform and Non uniform motion
Uniform motion
- The motion in which object covers equal distances in equal intervals of times is known as uniform motion.
- The velocity of object remains constant throughout the motion.
- Motions of planets around the sun, motion of hands of clock, parade of NCC cadets are some important examples of uniform motion.
- As the velocity of object performing the uniform motion is constant, then the acceleration of object becomes zero.
- The motion of blades of fans running at constant speed, a train running at 60 kmph from last one hour.
- During uniform motion, the distance-time graph is always straight line.
Consider a boy starts cycling and traces distance in given time as below,
Time (second) |
0 | 2 | 4 | 6 | 8 | 10 |
Distance
(meter) |
0 | 3 | 6 | 9 | 12 |
15 |
Non-uniform motion
- The motion in which object covers unequal distances in equal intervals of times is known as uniform motion.
- The velocity of object varies throughout the motion.
- Motions of children enjoying the giant wheel in fun fair, running competition of students in which all are taking different times to run the same distance.
- As the velocity of object performing the non-uniform motion is variable, then the acceleration of object becomes non zero.
- Consider the motor cyclist increases his speed randomly ( increases and decreases) after intervals of one minute, then there in non zero acceleration
- During non uniform motion, the distance-time graph is always straight line.
Consider a boy cycling on hilly surfce and traces distance in given time as below,
Time (second) |
0 | 2 | 4 | 6 | 8 | 10 |
Distance
(meter) |
0 | 2 | 5 | 10 | 13 |
