How does the object slide down the surface (With friction negligible)
You'll need to be more specific. Tell us what you know and what you don't understand.Shardul Khare said:How does the object slide down the surface (With friction negligible)
.You have canceled the Normal and Gravitational force only that that specific point right? But we have learned that gravity is always acting on that object...Wont it have any gravitational force when sliding?mamadou said:It's the Px vector component of the vector P that makes the object slides down along the surface , because the Py component cancels with the R vector , by using 2'nd motion law : P + R = m.a , we can break the P into sub component vectors : Px + Py + R = m.a , the Py and R cancel each other's , so you'll get :
m.a = Px , that means that the object is moving in the direction of the vector Px so it's sliding down . look :
it does, but its the component of the force and the magnitude of friction that opposes the direciton of motion on the slope that determines if it slides.Shardul Khare said:.You have canceled the Normal and Gravitational force only that that specific point right?

Yes, Lemme clear my doubt, The object is kept on an inclined surface...It won't go down because of the Normal force...And will slide down due to its horizontal component,right? But won't it have Normal foce on each point of its path while sliding after the initial Normal is cancellled out with the component AT THAT POINT?mamadou said:I didn't cancel the "GRAVITATIONAL" force , but the "Y COMPOONENT" of the gravitational force , which means that the x component is still remaining .
The force of friction when sliding on an inclined plane depends on the angle of inclination, the weight of the object, and the coefficient of friction between the object and the surface of the plane. It can be calculated using the formula Ff = μmgcosθ, where μ is the coefficient of friction, m is the mass of the object, g is the acceleration due to gravity, and θ is the angle of inclination.
The angle of inclination has a direct impact on the speed of sliding on an inclined plane. The steeper the incline, the faster an object will slide due to the increased gravitational force pulling it down the plane. As the angle decreases, the speed of sliding also decreases.
The weight of an object has a direct relationship with the force of friction when sliding on an inclined plane. As the weight of the object increases, the force of friction also increases, making it more difficult for the object to slide down the plane. This is because the weight of the object increases the normal force between the object and the plane, which in turn increases the force of friction.
The coefficient of friction is a measure of the roughness or smoothness of the surface of the inclined plane. A higher coefficient of friction means there is more resistance between the object and the surface, making it more difficult for the object to slide. On the other hand, a lower coefficient of friction means there is less resistance, making it easier for the object to slide down the plane.
Sliding on an inclined plane has many practical applications in everyday life. Some examples include using a ramp to load heavy objects onto a truck, using a wheelchair ramp to access buildings, and using a playground slide for recreation. It is also used in various industries such as construction, transportation, and sports equipment design.
