Why is there frictional force? Is friction an applied force? Does kinetic friction oppose motion? What factors affect the friction force between two surfaces? How to calculate force of friction on an inclined plane Is centripetal force caused by friction?
How to calculate force of friction on an inclined plane If a 20kg box accelerates down a 30-degree slope at 10 m/s^2, what is the magnitude of the friction? A 2.3 kg particle is projected with an initial speed o...
This is the wedge force calculation, but you can't use it to directly calculate the force exerted by the wedge in a particular material because it doesn't take friction into account. You encounter more friction cutting through cheese than you do cutting through butter, and the friction acts ...
Next, we can use the equation for work (W = fs) to calculate the force (f) acting on the object as it moves down the ramp. This force is equal to the weight of the object (mg) plus the frictional force (μmgcosθ). Finally, we can substitute the values we have calcul...
Force: Force is defined as a vector physical quantity that is the time rate of change of linear momentum and it can be resolved into sine and cosine trigonometric rectangular components. Answer and Explanation:1 Diagram Representation The weightmgof the body is broken down into two of its compo...
and Ef is the kinetic energy at the bottom : (1/2) m v2 = (1/2) 60 x (18)2 = 9720. This means that the friction did 9720 - 42336 = - 32616 J of work. This number is negative because friction is a dissipative force that removes mechanical energy from the ...
The direction of the [dry, kinetic] frictional force on an object is opposite the direction of the object's *relative* motion, with respect to whatever object that it is sliding against. The frictional force is always in a direction such that the force tries to stop/reduce the object fr...
How do forces relate to angles?Calculating VectorsUnder ideal conditions forces and motion occur in perfectly straight lines. In real life however forces frequently act at angles to each other; when this happens we must use vectors to calculate the resulting forces and motion....
How to calculate the velocity of a pendulum How is force and laws of motion similar to speleothems? How does pressure relate to force? Does string tension cause centripetal force? How is kinetic energy related to momentum? Is tension force and normal force the same?
If the coefficient of kinetic friction is 0.3 and the Block is displaced by a distance of 10cm along the inclined . Calculate the work d In an inclined plane problem, why is the angle formed between the force due to gravity vector and the perpendicular force vector equal to the angle...
