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. Angular momentum... Angular velocity.... Linear momentum....Linear velocity
- 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
A body with translatory motion possesses momentum of two types, linear and angular. Similarly, a body in rotatory motion possesses velocities; angular and linear.All options except B are incorrect because they do not fit into the blanks properly. A motion in which all the points of a body moving uniformly in a single direction is called translational motion. When an object undergoes translational motion, there is no change in its orientation. In this motion, all the particles of the object move parallel to each other. So the objects moving with translatory motion possess linear properties.Rotatory motion is the motion that occurs when a body rotates on its own axis. A few examples of the rotatory motion are as follows: The motion of the earth about its own axis around the sun is an example of rotary motion. So the objects moving with rotatory motion possess angular properties

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.
