Question

Is motion in a straight line kinematics?

Answer 1

• As we know that kinematics describes motion appearance without considering the motion causes.

• Along a straight line, kinematics are limited to motion.

• The straight line is a one-dimensional motion.

• If the position of an object changes with time, then the object is in motion.

• Newton's first law of motion;

        with constant velocity objects that do not experience any net force, will continue to move in a  straight line until they are subjected to a net force.
