Detailed Solution
Download Solution PDFThe correct answer is periodic motion.
Key Points
- A motion that repeats itself after a set amount of time is called periodic motion.
- When a body repeatedly moves along a certain path over a predetermined amount of time, it is said to be exhibiting periodic motion.
- The term "time period" refers to the interval of time after which the body's motion is repeated.
- Examples of periodic motions:
- earth’s rotation around the sun
- motions of the hands of a clock
- When a body moves in a non-periodic manner, it doesn't repeat the same motion after a set amount of time.
- A bouncing ball, for instance, moves in a non-periodic manner.
Additional Information
- Rectilinear motion or linear motion is a type of motion that only moves in one direction or on one axis.
- Every parameter connected to motion is pointed in the same direction.
- Consequently, the motion is sometimes referred to as one-dimensional motion.
- Examples:
- soldiers walking on the ground or marching during the event.
- arrow fired by an archer
- a car moving on a road
- a person jogging in park
- An object moving while rotating in a circle is referred to as being in circular motion.
- There are two types of circular motion: uniform and non-uniform.
- The angular rate of rotation and speed will remain constant in uniform circular motion, whereas the rate of rotation will fluctuate in non-uniform motion.
- Common examples of circular motion:
- rotating ceiling fan
- moving car’s wheel
- blades of windmill
- Merry-Go-Round
- When the object rotates for half circle and comes back, this is called semi-circular motion.
