On this page I put together a collection of friction problems to help you understand the concept of friction better. The required equations and background reading to solve these problems are given on the friction page and the equilibrium page .
Friction is a force between solid surfaces in contact. Friction is tangential to the surface and points opposite the direction of motion (or intended motion).
Common force of friciton problems with solutions using force applied, wight, normal force, and the cefficient of friction to find acceleration.
What friction force will produce a net force of 6.0 N? friction = 2 N left . How does the magnitude of the friction force on a box on a ramp change when the angle of the ramp increases? Free Body Diagram . Friction decreases because the normal force decreases . Review - Which law of motion best explains this?
Friction Problems For the following problems, calculate the force of friction acting on the object. 1. A 10 kg rubber block sliding on a concrete floor (µ=0.65) @ ⁄ A 2. A 8 kg wooden box sliding on a leather covered desk. (µ=0.40) @ ⁄ A 3. A 37 kg wooden crate sliding across a wood floor. (µ=0.20) @ ⁄ A 4.
a) Assuming there is no friction between block 4 and the inclined plane, find the acceleration (magnitude and direction!) of the acceleration of block 5. (0.55 m/s2 up!) b) Assuming there is no friction between block 4 and the inclined plane, find the tension in the string. (24 N)
