Answer:
The basic form of mechanical motion is the uniform linear movement. The name itself says that it is a uniform movement of a physical point in a straight line, i.e. with the same speed. The speed of linear straight-line motion is a change in the position of the object within a given time interval. The basic distinguishing of a uniform linear movement is that the displacement is equal to the passed distance. When a body passes equal distances at equal time intervals, we say that it moves at the same speed. The relation of the distance and time to a linear uniform movement is always the same. Constant speed means that the object passes equal movements for equal time intervals, always in the same direction in a straight line. In other words, the speed is equal to zero. In the case of circular movement, all parts of the object move around the circles lying in similar planes, whose centers are on the axis of rotation. The Equations describing the rotational motion of the object can be derived from the equation of translational motion by putting in its place of the path
s = angle of rotation
φ= (rad), velocity
c = angular velocity
ω (rad/s) acceleration a = angular acceleration α (rad/s²)

Examples of uniform motions.
1. The hr. hand of clock - It moves with uniform speed, completing movement of a specific distance in an hour.
2. An airplane cruising at a level height and a steady speed.
3. A car going along a straight level road at steady speed.
4. A vibrating spring in a sewing machine.
5. A ship steaming on a straight course at steady speed.
6. A train going along the tracks at steady speed.
7. Earth moving round the sun is a uniform motion.
8. A cooling fan running at a constant speed.
9. Movement of fan.
10. A pendulum having equal amplitudes on both sides.

Hope this is enough
Explanation:
1.Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation.
2.These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.
3.Non-Uniform Motion. Definition or meaning. When a body moves along a straight line with uniform speed or steady speed is called Uniform motion. When a body moves along a straight line but with variable or change in speed is called non-uniform motion
4.Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
5.The formula for speed is change in distance divided by change in time. The formula for velocity is change in displacement divided by change in time.
6.Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
