Question

state the condition when a force produces: a) translational motion b) rotational motion​

Answer 1

$\huge \bold{ANSWER}$

◼A rigid body when acted upon by a force, can have two kinds of motion :

▶Linear or translation motion .

▶Rotational motion.

$\bold{LINEAR \: OR \: TRANSLATION \: MOTION}$

When a force acts on a stationary rigid body which is free to move, the body starts moving in a straight path in the direction of force. This is called linear motion.

CONDITION IS CLEARED IN DEFINITION ITSELF :-

▶The body should be rigid.

▶The body should be free to move.

EXAMPLES :-

✳On pushing a ball lying on floor it begins to move.

$\bold{ROTATIONAL \: MOTION}$

When a body is pivoted at a point and the force is applied on the body at a suitable point, it rotated the body about the axis passing through the pivot point. This is the turning effect of the force and the motion of the body is called rotational motion.

CONDITION IS CLEARED IN DEFINITION ITSELF :-

▶The body should be rigid.

▶The body should be pivoted from a point.

EXAMPLES :--

✳A wheel is pivoted at its centre and if force is applied tangentially on its rim it start rotating.

Answer 2

Answer:

i) it will move in straight path

b) it will move in rotation motion
