Answer:
Explanation:
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.
In rectilinear motion all particles of the body travel the same distance along parallel straight lines. In curvilinear motion the trajectories of individual particles of the body are curved, although the orientation of the body in space does not change.
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.
