What is Uniform Motion?
Uniform motion happens when an object travels in a straight line at a constant velocity — equal distances in equal time intervals, with zero acceleration.
Uniform motion is straight-line movement at constant speed and direction, so distance is simply d = v·t and acceleration is always zero.

Step-by-step worked examples
A train moves at a constant 25 m/s for 40 s. How far does it travel?
d = v·t d = 25 × 40 = 1000 m
A conveyor belt carries a box 12 m in 6 s at constant speed. Find the speed.
v = d/t v = 12/6 = 2 m/s
A drone hovers forward at 4 m/s uniformly. How long to cover 100 m?
t = d/v t = 100/4 = 25 s

Common mistakes
Thinking 'uniform motion' just means 'moving'. — Correct: It specifically means constant velocity — same speed, same direction, no acceleration.
Believing a curved distance–time graph can represent uniform motion. — Correct: Only a straight line represents uniform motion; a curve means changing speed.
Assuming uniform motion requires zero speed at some point. — Correct: Speed stays constant and non-zero throughout — it never slows to zero.
Confusing uniform motion with uniformly accelerated motion. — Correct: Uniform motion has zero acceleration; uniformly accelerated motion has constant, non-zero acceleration.
FAQ
What is uniform motion?
Motion along a straight line at constant velocity, with equal distances covered in equal time intervals.
What is the uniform motion formula?
d = v·t, where v is the constant velocity and t is time.
How to calculate distance in uniform motion?
Multiply the constant velocity by the total time travelled: d = v·t.
What are examples of uniform motion?
A train cruising at constant speed on a straight track, or a conveyor belt moving at fixed speed.
