A body having translatory motion possesses _ and _. In the same way a body having rotatory motion possesses _ and _.
Correct answer: B. Linear velocity... Linear momentum... Angular velocity... Angular momentum
- A. None of them
- B. Linear velocity... Linear momentum... Angular velocity... Angular momentum
- C. Linear momentum... Angular momentum... Linear velocity... Angular velocity
- D. Angular velocity... Angular momentum... Linear momentum... Linear velocity
Explanation
The correct answer is: Linear velocity... Linear momentum... Angular velocity... Angular momentum.In translatory motion, all points of a body move uniformly in a single direction, involving linear properties such as linear velocity and linear momentum. This type of motion does not change the orientation of the object.In contrast, rotatory motion occurs when a body rotates around its own axis, involving angular properties like angular velocity and angular momentum. For example, the Earth's rotation about its axis is a type of rotatory motion.All options except B do not properly align the motion types with their respective properties, which is why they are incorrect.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
