Question

How are the motions of a wheel of a moving bicycle and a mark on the blade of a moving electric fan different? Explain

Answer 1

Step 1:

1. The wheels of a moving bicycle consist of two different motions.
2. Since the bicycle moves forward along with the circular motion of the wheels, it consists of two different motions.
3. One is rectilinear motion and the other is circular motion.
4. The moving blade of a fan only has a circular motion as the fan remains stationary only as the blades rotate.

Step 2:

Definition Of Rectilinear Motion

1. Rectilinear motion is the motion of an object that moves in a straight path.
2. For example, a train moving on a track, a parade, and coins tossed in the air are all in rectilinear motion.

Step 3:

Definition Of Circular Motion

1. Circular motion is the motion of an object that moves in a circular path about a fixed point.
2. Circular motion traverses a circular path.
3. The hands of a clock, a merry-go-round, the blades of a fan, the wheel of a moving vehicle, and satellites are all good examples of circular motion.
