Question

Answer the following 1.Distinguish between rectilinear and circular motion. 2.List the points to be kept in mind while using a ruler to measure the length of a line segment. RESPOND ASAP

Answer 1

Answer:

A1.Rectilinear motion is the motion of an object that moves in a straight path. For example, a train moving on a track, a parade, coins tossed in the air are all in rectilinear motion. Circular motion is the motion of an object that moves at a fixed distance from a fixed point. Here, all objects rotate in circular motion.

A2.The ruler must be placed parallel to the object whose length is being measured. 2. Eyes should be kept exactly above the point where the measurement is being taken.
