Types Of Motion
According to Directions
One dimensional motion is the motion of a particle moving along a straight line.
Two dimensional motion A particle moving along a curved path in a plane has 2-dimensional motion.
Three dimensional motion Particle moving randomly in space has 3-dimensional motion.
According to state of motion
A body is said to be in a state of uniform motion if it travels equal distances in equal intervals of time.
If the time distance graph is a straight line the motion is said to be uniform motion.
A body has a non-uniform motion if it travels unequal distances in equal intervals of time.
Example. a freely falling body.
Time - distance graph for a body with non-uniform motion is a curved line.
