Distinguish between:
(a) Rectilinear and Curvilinear motion
(b) Rotation and Revolution
Give one example of each from our daily life.
Answers
Explanation:
In rectilinear motion the body travels in a straight line whereas in curvilinear motion the body travels in a curved path. In rectilinear motion the body can travel with uniform velocity whereas in curvilinear motion the velocity keeps changing as the direction keeps changing.
When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution.
Answer:
a:. A motion is move at a straight motion is called rectilinear motion. example: a vehicle at straight bypass.
A motion is not move in a straight motion or move in a curved motion is called curvilinear motion. example: a playing football.
b: An object rotate on its own axis is called rotation. example: a spinning top.
An object move circular around an object is a called revolution. example: earth revolves around the sun.
