Uniform motion

Meaning

Things around us, such as the movements of a clock’s hands, the rotation of blades of a ceiling fan, the direction of a ball, the movement of an asteroid, and the earth’s rotation and revolution, are some examples of uniform motion. More precisely, uniform motion is the motion of an item in which the object moves in a straight path, and its velocity is constant along that line as it travels equal distances in similar intervals of time, regardless of the time.

When something changes locations or goes from one point to another, it is said to be in motion, and uniform motion is defined as the movement of an object at a constant and unchanging pace.

Example

Suppose a car is covering a distance of 4 meters every 2 seconds. Its distance is said to be uniform since it covers equal distance in an equal time interval.

So, in the situation of uniform motion, we can determine the overall distance covered if we know the constant distance traveled for each time and the entire time length of motion.

Equation

The uniform motion formula is d = St,

where d, or distance, relates to the motion’s real length.

The speed is denoted by the letter S.

The term t, or time, relates to the length of time that the motion lasts.

Graph 

A position-time graph of an object’s motion can be used to determine if it has uniform motion. The motion is uniform if the graph forms a straight line with a constant slope, and the slope of the graph equals the object’s velocity.

Properties

• The velocity of uniform motion is independent of the origin.
• In uniform motion, the velocity is independent of the time interval chosen.
• The amount of the displacement for uniform motion is in the same direction along a straight line and is equal to the actual distance covered by the object.
• If the object is traveling to the right of the origin, the velocity is positive; if the object is going to the left of the origin, the velocity is negative.
• No force is required to maintain the motion of an object in uniform motion.
• In uniform motion, the instantaneous velocity is always equal to the average velocity since the velocity is constant at each instant or at each location along the path.

List of Examples

• A clock’s hour hand
• A car traveling at a constant speed along a straight, flat route
• An airplane that is cruising at a constant height and speed
• A ship sailing in a straight line at a constant pace
• A train moving at a steady pace along the tracks
• A cooling fan that runs at a constant speed
• The Earth revolving around the sun
• The movement of a fan
• The amplitudes of both sides of a pendulum being equal
• A sewing machine’s vibrating spring
• Raindrops falling at a consistent rate

Conclusion

The term “motion” refers to a change in an object’s position. Three important ideas are utilized to classify types of motion: speed, distance, and time. Motion can be defined as uniform or non-uniform depending on the time and distance traveled.

Uniform motion occurs when an object moves at a constant speed in a specific direction at regular intervals of time.
