Motion in One Dimension – Notes

Motion and Measurement of Distance – Rest and Motion

A body is said to be at rest when it remains in its position for a long time (there is no change in its position).

A body is said to be in motion if it is changing its position with respect to its surrounding and time.

Motion that occurs along a straight line is called rectilinear motion.

Circular motion is the motion of an object, which moves at a fixed distance from a fixed point.

Periodic motion is a motion that repeats itself at regular intervals.

Sometimes an object can display combination of different types of motion.
