A ball rolling at a constant speed at the same rate of speed on a still surface.
As shown by Einstein's Principle of Relativity, motion is a necessarily relative concept: what appears to be moving from one frame of reference may not appear to be moving, or moving in the same way, from another frame of reference. From a physical point of view, all frames of reference are given equal validation. So uniform motion itself will also be a relative concept. If an object A is in uniform motion relative to another object B, then from B's view there appear to be no force applied to A; i.e. it appears to be neither accelerating nor decelerating, nor changing directions or moving in a curve. The same should apply vice versa.
translation: uniform motion is something moving in a straight line at a consistent speed
Constant velocity is known as uniform velocity, which is achieved when the net force (or resultant force) of a body is zero i.e. there is no external forces causing the body to accelerate or decelerate.
To look at it from a Calculus dimension:
If the derivative of the position vector with respect to time = 0 in an inertial reference frame.
i.e. it is moving with constant speed in a direction in an inertial reference frame.
I prefer the following statement which is equivalent to the above:
If the second derivitive (i.e. acceleration) of the position vector is 0 in any one inertial frame, then it is 0 in all inertial frames and there exists at least oneinertial frame in which the first derivitive (i.e. velocity) of the position vector is 0.
In short:
Neither speed nor direction of motion changes.
if an object travels equal distance in equal intervals of time then the motion is said to be uniform.
Constant motion is a mechanics terms meaning the quantity that is conserved throughout the motion. Examples of constant motion are specific linear momentum and specific energy.
An object that is speeding up at a steady rate.
It means constant speed in a straight line.
Earth, Hands on a clock, etc.
if a body can cover equal distance in equal intervals of time then the body is said to be with uniform motion
Think of uniform as everything moving together. For example, in uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. If the motion was non-uniform the distance of the body from the axis of rotation would vary.
How the weight of the body is balanced in a horizontal circle?
"Think of a simple single cylinder engine....crankshaft goes round & round,piston goes up & down,connecting rod keeps the two tied together...wa la!" This type of linear motion is known as reciprocating motion, where the linear motion is a repetitive up and down, or back and forth action. The linear motion velocity of a wheel and crank system is not uniform and conforms to a sinusodial curve, i.e. it is slowest at the 0º and 180º positions and fastest at the 90º position. To get uniform linear motion from uniform rotary motion, you can use a threaded shaft and thread follower arrangement, or a rack and pinion. btw, it's "voila!".
An inertial reference frame is a frame ... a box, a laboratory, a space capsule etc. ... in which Netwon's laws of motion hold true. Example: My office on the earth is not an inertial reference frame. An object in motion doesn't "remain in constant uniform motion without application of an external force", because of air resistance. Also, an object released in the middle of the air doesn't stay there, it accelerates toward the floor.

uniform and non uniform motion uniform motion [ equal distance in equal intervals of time is known as uniform motion] non uniform motion [equal distance at unequal intervals of time is known as non uniform motion]
"Non-uniform" motion is "accelerated" motion.
linear is which is on a straight path and circular motion is which has a curved path. *In a uniform linear motion,the velocity is constant and the acceleration is zero.So,uniform linear motion is an unaccelerated motion. *In uniform circular motion the velocity can be variable although the speed is uniform.So,it is an accelerated motion.
The spinning top has uniform motion.
What is the meaning of uniform accelarated motion?
yes the motion of earth around the sun is uniform
yes, acceleration is constant in uniform circular motion
in uniform motion velocity not changes with time but in non uniform motion velocity changes with time.
motion that is always constant [Either acceleration or deceleration that is called uniform motion......... motion that undergoes a change in velocity,either by changing speed or changing direction,,,,,that.s changes are called non uniform motion......
Uniform acceleration motion is a type of motion where the acceleration value is constant.
It travels in uniform motion when there are no net forces acting on it.
Uniform motion refers to motion with constant (including zero) velocity: that is, the same speed and in the same direction. Non-uniform motion can refer to motion in which the speed or direction of motion are not constant throughout the period under consideration.
