Types Of Motion.
Rectilinear motion Curvilinear motion
2. Examples are a car moving on a straight road and a train moving on a straight track. 2. Examples are a stone thrown up in the air at an angle and a car taking a turn.
Answer: Types of Motions:
1. Rectilinear motion- Rectilinear motion is a linear motion in which the direction of the velocity remains constant and the path is a straight line.
Examples- The use of elevators in public places is an example of rectilinear motion. Gravitational forces acting on objects resulting in free fall is an example of rectilinear motion. Kids sliding down from a slide is a rectilinear motion.
Circular motion- Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
Examples- Any point on a propeller spinning at a constant rate is executing uniform circular motion. Other examples are the second, minute, and hour hands of a watch.
Periodic motion- This is a type of motion where the object repeats its motion after a fixed interval of time.
Examples- The motion of a pendulum, the motion of a spring, the vibration of a guitar string, the rotation of the Earth over its axis, the revolving of the Earth around the Sun, the revolving of the Sun around the center of the Galaxy, etc.
Rotational motion- The motion of a rigid body which takes place in such a way that all of its particles move in circles about an axis with a common angular velocity; also, the rotation of a particle about a fixed point in space.
Examples- The blades of a fan, a spinning wheel.
