Question

write in brief about the linear motion andcurvilinear pairwith examples

Answer 1

What is Linear Motion?

Linear motion meaning the change of position of an object with respect to time interval. We live in a universe that is in continuous motion. The fundamental particle of a matter i.e. atom is also in constant motion. Every physical process happening in the universe is composed of some sort of motion. The motion can either be fast or slow, but motion always exists.  Motion is described in terms of the following terms: Distance, Displacement, Speed, and Time as discussed above.In general, a body will be said to be in motion if it changes its position with respect to a reference point and time. While describing the Linear Motion we require only one coordinate axis along with time to describe the motion of a particle then it is said to be in linear motion or rectilinear motion. In linear motion, the particles will move from one point to another point either in a straight line or a curved path. Depending on the path of motion linear motion is further subdivided divided as:

•Rectilinear Motion – It is a path of motion in a straight line.

•Curvilinear Motion – It is a path of motion in a curved line.

Types of Linear Motion

An object is in a linear motion if the object moves in a straight line, on the other hand, an object is in a rectilinear motion if two objects move in a straight line and are parallel to each other. The two types of linear motion are uniform motion and non-uniform motion but the three types of rectilinear motion are uniform rectilinear motion, uniformly accelerated rectilinear motion and rectilinear movement with non-uniform acceleration.

1.Uniform Linear Motion: When an object travels at a constant speed with zero acceleration.

2.Non-Uniform Linear Motion: When an object travels at an irregular speed and acceleration. 

Answer 2

Answer:

An example of linear motion is an athlete running 100m along a straight track. ... Linear motion is the most basic of all motion. According to Newton's first law of motion, objects that do not experience any net force will continue to move in a straight line with a constant velocity until they are subjected to a net force.
