How can frictional forces be reduced? How is friction force related to surface area? How does frictional force affect the velocity of an object? How are frictional forces reduced in car …

Bicyclist must create a centripetal force to keep on the curve. Without it he will continue going straight and, since the wheels are directed towards the curve, the bicycle will turn and he will …

0.8N up the slope. Start by setting your problem up in a diagram like so: (g is the acceleration due to gravity, value =9.81ms^-2) Then think about which formulae and physics concepts you will …

Assign a positive or negative sign to the force depending on its direction, then add the two forces to get the net force. Acceleration is a vector quantity, meaning that it also has direction in it. …

Jan 19, 2016 · If a 11kg object moving at 15ms−1 slows down to a halt after moving 225m, what is the coefficient of kinetic friction of the surface that the object was moving over? Physics …

An object with a mass of 6kg is hanging from a spring with a constant of 12 kg s2. If the spring is stretched by 1m, what is the net force on the object? Physics Forces and Newton's Laws …

The given situation"*" is depicted in the figure below Let a be side of the square. As shown in the figure charge Q placed in one corner experiences three forces. Force vecF_3 due to charge Q …

An object, previously at rest, slides 5m down a ramp, with an incline of 3π 8, and then slides horizontally on the floor for another 11m. If the ramp and floor are made of the same material, …

A box with an initial speed of 8 m s is moving up a ramp. The ramp has a kinetic friction coefficient of 4 5 and an incline of π 6. How far along the ramp will the box go? Physics Forces and …

An object with a mass of 6kg is pushed along a linear path with a kinetic friction coefficient of uk(x) = 2 + csc x. How much work would it take to move the object over #x in [pi/8, (3pi)/8], where x …
