Motion and The Effect of Motion

Linear motion = movement in a straight line

Means movement

Motion

From the word line

Means in a straight line​

Linear

What is linear motion?

Position of object will also be different. If the position is same as before, there is no movement, no motion

Position will change

Because we need to compare before and after. If only one time, we didn't know how it move

Time will change

When something is in motion..

Shortest distance between two point.

Just pick first and last point and measure distance

Vector quantity

Displacement is 5 meter to the right​

Displacement (s)

All length traveled by an object

Is a scalar quantity (no direction)

"Distance traveled is 5 meter"​

Distance (d)

First, we talk about position change
