Frictional force that fluids exert on an object is called
The bodies of aeroplanes, missiles, rockets, cars are streamlined to reduce friction with air. This friction forces is called
The bodies of aeroplanes, missiles, rockets, cars are streamlined to reduce friction with air. This friction forces is called air resistance.
The force of friction between two bodies in contact is
Friction due to water and air can be reduced by suitably designing the shape of the objects. This is called
Sprinkling of powder on the carromboard ____ friction.
The force of friction that exists between the surfaces in contact when one body slides over the surface of other body is called ____ friction.
Which of these frictions is largest in magnitude in comparison to other frictions?
What type of friction does not allow two surfaces to slide upon one another?
When two bodies are in contact, friction opposes the relative motion between
