Put a one rupee coin over a piece of card paper placed on an empty glass push the card with a sudden stroke of finger card will move ahead while the stone fall in glass, Why?
In most cases, kinetic friction decreases slightly with sliding speed, even in a vacuum where there's no effect from air.m.e.t.a. said:This trick relies on the fact that the coefficient of kinetic friction, [itex]\mu_{k}[/itex] is not proportional to sliding speed [itex]v[/itex]. If you double the sliding speed, the resulting coefficient of kinetic friction less than doubles.
The One Rupee Mystery is a demonstration of the principle of inertia. The coin falls and the card moves due to the natural tendency of an object to resist changes in its state of motion. In this case, the coin resists being pushed off the card and the card resists falling off the table, leading to the observed movement.
The movement in the One Rupee Mystery is affected by the mass and size of the coin and the card, the force applied to the coin, the surface friction between the objects, and the angle at which the objects are placed on the card.
Yes, the One Rupee Mystery can be used to demonstrate the principle of inertia, which is a fundamental concept in physics. It can also be used to explain other related principles such as Newton's first law of motion and the concept of center of mass.
Yes, the outcome of the One Rupee Mystery can be changed by altering the factors that affect the movement, such as by changing the mass or angle of the objects. It can also be influenced by external factors such as air resistance or external forces applied to the objects.
The One Rupee Mystery helps us understand the concept of inertia, which is present in many everyday situations. For example, inertia is why we feel a jolt when a moving vehicle suddenly stops or why we need to hold onto objects when a car turns. Understanding this concept can also help us make predictions and decisions in various situations.
