Masses of objects are surrounding us, some stay at rest while some are in motion. Speed. Analysing Motion Graphs Acceleration of a train running from one station to another is a non-uniform acceleration. Average Speed – If the motion of the object is non-uniform then we calculate the average speed to signify the rate of motion of that object.. For Example, If an object travels 10m in 3 seconds and 12m in 7 seconds.Then its average speed would be: Total distance travelled = 10 m + 12 m = 22m. Example of uniform motion is - car moving with constant speed say 10 km/h Example of non-uniform motion is - ball falling from a height ( it is motion in which the body covers unequal distances in equal intervals of time) Graph of Non - Uniform Motion is Curved Line. For example, in the telecast of a one-day cricket match, vertical bar graphs show the run rate of a team in each over. A body is in non uniform motion if it covers unequal distance in equal intervals of time. In classical physics and special relativity, an inertial frame of reference is a frame of reference that is not undergoing acceleration.In an inertial frame of reference, a physical object with zero net force acting on it moves with a constant velocity (which might be zero)—or, equivalently, it is a frame of reference in which Newton's first law of motion holds. Therefore, we can say that they are rotating with non-uniform velocity. Now, people usually get confused between uniform motion and uniform acceleration. A vibrating spring in a sewing machine. A ball falling from the cliff, A bullet fired from the gun It could be both uniform and non-uniform motion. (ii) Non-uniform acceleration : When a body moves with unequal velocity in the equal interval of time, the body is said to be moving with non-uniform acceleration. We know what motion is. If the time distance graph is a straight line the motion is said to be uniform motion. (d) Example of uniform retardation: If a car moving with a velocity 'v' is brought to rest by applying brakes, then such a motion is an example of uniform retardation.
