Answer 1

Answer:

Pls follow me!

ans1:- In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.

ans2. a) In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time.

ans3. periodic motion

ans3. Similarities between the motion of a bicycle and a ceiling fan: ... Both have circular motion about their respective fixed point.

Differences between the motion of a bicycle and a ceiling fan is that a bicycle has linear motion as it moves forward, whereas ceiling fan does not possess the linear motion.
