Difference between
Circular motion and rotational motion , living and non-living
Answers
Answer:
Circular motion And Rotational Motion-
The main difference between these types of motion is that circular motion is a special case of rotational motion, where the distance between the body’s centre of mass and the axis of rotation remains fixed. Rotational motion is based around the idea of rotation of a body about its center of mass. In rotational motion, the axis of rotation and centre of mass could change whereas in circular motion, the axis of rotation and centre of mass does not change. Circular motion is a movement of an object along the circumference of a circle or rotation along a circular path and can either have a constant angular rotation rate and constant speed, or it can exist with a changing rate of rotation.
Living and Non-living-
Living Things-
1)Living things are made up of living cells.
2)Require food, air and water.
3)Growth is present.
4)Reproduction is present.
5)Respiration present.
6)They can move on their own.
7)They are sensitive and respond to changes around them.
8)They excrete and get rid of waste materials from their body.
9)Living things have a definite life span after which they die.
Non- Living Things-
1)Non-living things are not made up of cells.
2)Do not require food, air and water.
3)Growth is absent.
4)Reproduction absent.
5)Respiration absent.
6)They cannot move on their own.
7)They are not sensitive and do not respond to changes around them.
8)They do not excrete.
9)Non-living things do not have definite life cycle.
