Question

Classify a ball thrown by a child into translatory, rotatory, and oscillatory motion.

Answer 1

1. Translatory motion: When an object (like a car or a scooter) moves in a line in such a way that every point of the object moves through the same distance in the same interval of time, the motion of the object is called translatory motion.
2. Rotatory motion: A body is said to be in rotatory motion if it moves about a fixed axis without changing its position.
3. Oscillatory motion: When a body moves to and fro (backward and forward) about its mean position, its motion is called oscillatory motion.
4. A ball thrown by a child will fall under the category of translatory motion.
