Why don't gravitational force have a repulsive nature

Posted by Anurag Choudhary 8 years ago

A Z 8 years ago

Gravitational force is attractive force. And as we know that attraction is the opposite of repulsion. So gravitational force is not repulsive in nature because a force can't have both nature.

Because the meaning of gravitation is attractive forces only.So here we consider attractive force. The nature of gravitational forces are attractive not repulsive..

Limitations of Bernoulli's theorem

Posted by Hardik Kumar 8 years ago

CBSE > Class 11 > Physics

1 answers

Prince Chaudhary 8 years ago

1. It applies ideally to the fluids with zero velocity or non-viscous fluids but not to the viscous fluids. 2. It is also stated that the kinetic energy remains constant throughout the tube but it is not so as some energy gets lost as heat. 3. While deriving the Bernoulli's theorem it is assumed that the velocity of the liquid that is flowing in the tube is equal/ constant at all parts but practically it is not correct too.
