Answer 2

Answer:

Motion in straight line

Motion

If an object changes its position with respect to its surroundings with time, then the object is in motion.

Rest

If an object does not change its position with respect to its surroundings with time, then it is called at rest.

Point Mass Object

An object can be considered as a point mass object, if the distance travelled by it in motion is very large in comparison to its dimensions.

One Dimensional Motion

If only one out of three coordinates specifying the position of the object changes with respect to time, then the motion is called one dimensional motion.

Two Dimensional Motion

If only two out of three coordinates specifying the position of the object changes with respect to time, then the motion is called two dimensional motion.

Three Dimensional Motion

If all the three coordinates specifying the position of the object changes with respect to time, then the motion is called three dimensional motion.
