Motion in One Dimension

Introduction to motion in one dimension:-
When a object moves in a straight line, motion of the object is called as motion in one dimension.

This type of motion is also called as linear motion. For example, 1. A ball moves on a level road in straight Line,  2. A ball is thrown straight up, 3. Free falling bodies. One dimensional motion is the simplest motion in physics.

I like to share this center of mass equation with you all through my article.

Some definitions orf motion in one dimensions:

Displacement-   the shortest distance between initial and final point is called as displacement.

Distance- the length of path travelled by object between initial and final points is called as distance travelled by object.

Speed – speed of object can be calculated by eq.  -         Speed = distance/ time.

Average speed-          average speed is the average of all speeds attained by object during trip.

It can be calculated by eq. -           average speed = total distance travelled / total time taken

Velocity-   velocity of the object can be calculated by eq.-    velocity = displacement / time

General Units of velocity is meter/second, kilometer/hour, miles/ hour. SI unit of velocity is meter/second.

Average velocity- average velocity of object can be calculated by eq. –

Average velocity = change in position / time interval

Acceleration- acceleration of the object is the rate of change of velocity. It can be calculated by eq.-

Acceleration = change in velocity / time interval

Uniform motion- when speed of the object is constant throughout one dimensional motion. Motion is called as uniform motion.

Non-uniform motion- speed in non-uniform motions is not constant and these motions have acceleration.

Having problem with Spin Quantum Number keep reading my upcoming posts, i will try to help you.

Distance- time graph : Motion in one dimension

Distance- time graph in one dimensional motion is drawn between distance travelled and time. For uniform one dimensional motion this graph shows a straight line. Slope of line represents the velocity of motion. For non-uniform one dimensional motion, this graph shows a curve.
