To find normal force on an incline, use the equation N = mg cos(x), “m” being the object’s mass, “g” being the acceleration of gravity, and “x” being the angle of incline. Then, use a calculator to find the cosine of the angle, and write down that value. How do you do angled forces in […]
The coefficient of friction between wood and wood is around 0.25-0.5 (static) & 0.2(kinetic). Every coefficient of friction is always less than or equal to one. (Only static friction coefficient in Rubber on Concrete is 1). What is the coefficient of friction for wood on lab table? So the static friction coefficient of wood-on-wood is […]
Kepler’s laws of planetary motion mark an important turning point in the transition from geocentrism to heliocentrism.
