What is sudo force or centrifugal force

Posted by Dewang Singh 8 years, 3 months ago

CBSE > Class 11 > Physics

1 answers

Swarnali Mondal 8 years, 3 months ago

Pseudo Force and centrifugal force are two different terms. Pseudo force is only a mathematical technique which is used in solving numericals whereas centrifugal force is the force, arising from the body's inertia, which appears to act on a body moving in a circular path and is directed away from the centre around which the body is moving.

Sohome Chowdhury 8 years, 3 months ago

THE MAXIMUM RESISTIVE FRICTIONAL FORCE,AFTER WHICH A BODY STARTS TO MOVE IS KNOWN AS LIMITING FRICTIONAL FORCE.LIMITING FRICTIONAL FORCE IS ALSO KNOWN AS MAXIMUM STATIC FRICTION.

Divya Kumari 8 years, 3 months ago

Maximum value of static friction force is called limiting friction. Limiting friction force depends on the nature of surfaces in contact and normal reaction between them.

Hardik Sojitra 8 years, 3 months ago

torque is defined as the <a href="https://en.m.wikipedia.org/wiki/Cross_product" title="Cross product">cross product</a> of the vector by which the force's application point is offset relative to the fixed suspension point (<a href="https://en.m.wikipedia.org/wiki/Euclidean_vector" title="Euclidean vector">distance vector</a>) and the force vector, which tends to produce rotational motion.

Why water drop is in circular shape?

Because of surface tension

Jwalant Patel 8 years, 3 months ago

The drop takes this shape because water molecules tend to stick to each other. So, when not confined by a container, and with nothing around it to distort its shape, a very tiny water drop is perfectly round like a ball because the water molecules are pulling inward toward each other.
