a large block of ice is being pulled across if frozen Lake the block of ice has a mass of 300 kg the coefficient of friction between two ice surfaces is small : uk = 0.05 what is the force of friction that is acting on the block of ice
Answers
Explanation:
Friction is the force that resists motion when
the surface of one object comes in contact
with the surface of another. The mechanical
advantage of a machine is reduced by
friction, or in other words, the ratio of output
to input is reduced because of friction. An
automobile uses one-quarter of its energy
on limiting the friction. Yet, it is also friction
in the tires that allows the car to stay on the
road and friction in the clutch that makes it
possible to drive. From matches to machines
to molecular structures, friction is one of the
most significant phenomena in the physical
world. In this article, let us discuss frictional
force and its different types.
Explanation:
friction is the force that resists motion when the surface of one object comes in contact with the surface of another . the mechanical advantage of a machine is reduce by fraction or in other words the ratio of output and input is reduced because of fraction .
