Answers
1•Linear motion is the most basic of all motion. ... In linear motion, the directions of all the vectors describing the system are equal and constant which means the objects move along the same axis and do not change direction.
•Example:An athlete running on a straight track of a park.
2•Rotational motion can be defined as the motion of an object around a circular path, in a fixed orbit.
•Example:Motion of wheel, gears, motors, etc.
3•Periodic motion, in physics, motion repeated in equal intervals of time.
•Example:a bouncing ball, a vibrating tuning fork, a swing in motion.
4•The motion of an object moving in a curved path is called curvilinear motion.
•Example:cyclist racing on curved tracks of velodrome, earth moving around the sun, a car taking a turn on a road.
5•A motion repeating itself is referred to as periodic or oscillatory motion.
•Example:Pendulum Clock. A pendulum clock is one of the perfect examples of oscillatory motion.
