Uniform Motion
Uniform motion happens when an object covers equal distances in equal time intervals. In uniform motion, speed stays constant and acceleration is zero.
Uniform Motion Simulator
Watch equal distances appear in equal seconds. Speed stays constant, so acceleration is 0 m/s².

What is Uniform Motion?
Uniform motion means the motion stays steady. If an object covers 3 meters in the first second, 3 meters in the next second, and 3 meters again in the next second, the speed is constant and the acceleration is zero.
Key Definition
Uniform motion is motion in which an object covers equal distances in equal intervals of time.
- Speed remains constant.
- Direction does not change in simple straight-line uniform motion.
- Acceleration is zero.
- Equal time intervals give equal distance intervals.
- Distance increases linearly with time.
Uniform Motion Formula
Distance = Speed x Time s = vt a = 0 Variables and units
- s = distance traveled
- v = constant speed
- t = time
- distance in meters, speed in m/s, time in seconds
Graph of Uniform Motion
Distance-time graph
- Straight line.
- Slope represents speed.
- Steeper line means greater speed.
Speed-time graph
- Horizontal line.
- Speed remains constant.
Acceleration-time graph
- Line at zero.
- Acceleration is zero.
Real-life Example of Uniform Motion
A ball rolls at a constant speed of 2 m/s for 5 seconds.
Speed = 2 m/s Time = 5 s Distance = 2 x 5 = 10 m Acceleration = 0 m/s² - A conveyor belt moving at constant speed.
- A clock hand moving steadily around its dial.
Solved Examples
View Solution: A ball moves at a constant speed of 4 m/s for 6 s. Find distance.
Use s = vt.
s = 4 x 6
s = 24 m
Final answer: 24 m
View Solution: A small drone moves 30 m in 10 s at constant speed. Find speed.
Use v = s / t.
v = 30 / 10
v = 3 m/s
Final answer: 3 m/s
View Solution: An object moves with uniform motion. Its speed is 5 m/s. What is acceleration?
In uniform motion, speed does not change.
Change in velocity is zero.
Acceleration = 0 m/s²
Final answer: 0 m/s²
Common Mistakes
- Thinking uniform motion means the object is not moving.
- Forgetting that speed is constant.
- Forgetting acceleration is zero.
- Confusing uniform motion with accelerated motion.
- Thinking distance-time graph is curved.
- Forgetting equal distances are covered in equal time intervals.
- Mixing up speed-time and distance-time graphs.
Quick Summary
- Uniform motion means equal distance in equal time.
- Speed is constant.
- Acceleration is zero.
- Formula: s = vt.
- Distance-time graph is a straight line.
- Speed-time graph is a horizontal line.
- Larger speed means steeper distance-time graph.
Practice Questions
1. Show Answer: A ball moves at 3 m/s for 8 s. Find distance.
Step: Identify whether the object has constant speed, then use s = vt or v = s / t.
Use s = vt. Distance = 3 x 8 = 24 m.
2. Show Answer: A drone moves 50 m in 10 s at constant speed. Find speed.
Step: Identify whether the object has constant speed, then use s = vt or v = s / t.
Use v = s / t. Speed = 50 / 10 = 5 m/s.
3. Show Answer: What is acceleration in uniform motion?
Step: Identify whether the object has constant speed, then use s = vt or v = s / t.
Acceleration is 0 m/s² because velocity does not change.
4. Show Answer: What shape is the distance-time graph for uniform motion?
Step: Identify whether the object has constant speed, then use s = vt or v = s / t.
It is a straight line. Its slope is the speed.
5. Show Answer: Does speed change in uniform motion?
Step: Identify whether the object has constant speed, then use s = vt or v = s / t.
No. Speed remains constant in uniform motion.
6. Show Answer: An object covers 5 m every second. Is this uniform motion?
Step: Identify whether the object has constant speed, then use s = vt or v = s / t.
Yes, if it continues covering equal distances in each equal time interval.
Frequently Asked Questions
What is uniform motion?
Uniform motion is motion in which an object covers equal distances in equal intervals of time.
What is the formula for uniform motion?
The common formula is s = vt, where s is distance, v is constant speed, and t is time.
Is speed constant in uniform motion?
Yes. In uniform motion, speed remains constant.
What is acceleration in uniform motion?
Acceleration is zero because velocity does not change.
What does the distance-time graph look like in uniform motion?
The distance-time graph is a straight line. Its slope represents speed.
What does the speed-time graph look like in uniform motion?
The speed-time graph is a horizontal line because speed remains constant.
Can an object move and still have zero acceleration?
Yes. If it moves with constant velocity, its acceleration is zero.
How does the uniform motion simulator work?
The simulator uses speed and time to calculate distance using s = vt. It shows equal distances covered in equal time intervals.
How can I increase the distance covered in the simulator?
Increase the speed or increase the total time. Since s = vt, distance increases when speed or time increases.
Is uniform motion the same as rest?
No. Rest means the object is not moving. Uniform motion means the object is moving at constant speed.
