How to solve friction problems in physics
WebIn this problem, we’re interested in the friction due to the normal force (i.e. the sliding friction). In this case, the n here will be n=0, since the friction force shouldn’t depend on the velocity, i.e. it’s proportional to the zeroth power of velocity (this is … WebOnce in motion it is easier to keep it in motion than it was to get it started, indicating that the kinetic friction force is less than the static friction force. If you add mass to the crate, say by placing a box on top of it, you need to push even harder …

WebNov 5, 2024 · In order to understand the technique to write dimensions of a derived quantity, we consider the case of force. Force is defined as: (1.4.1) F = m ⋅ a (1.4.2) F = [ M] [ a] The dimension of acceleration, represented as [a], is itself a derived quantity being the ratio of velocity and time. WebJul 9, 2015 · The answer is simple — mass 2 is not in equilibrium but instead it is accelerating downward. Since it's accelerating, the net force is not equal to zero (vector). This means that the tension should...
