WebDec 22, 2024 · The most straightforward kinetic friction definition is: the resistance to motion caused by the contact between a surface and the object moving against it. The force of kinetic friction acts to oppose the motion of the object, so if you push something forward, friction pushes it backwards. The kinetic fiction force only applies to an object ... WebJun 16, 2024 · The vector sum of the two forces will still be 80N in the downward direction, but the force on the middle support can become huge. This is how a nutcracker works. …

WebBig Ideas. Complete Problems 2 are just like Complete Problems 1, except they feature objects that are accelerating. Start by splitting the diagonal force into its horizontal and vertical components and drawings these onto the diagram. Then, we can apply Newton's 2nd Law, F net = m a, in both the horizontal and vertical directions: WebOct 17, 2024 · I would then add the horizontal forces together and then use Pythagoras's theorem with the vertical force to calculate the resultant diagonal force. This didn't come out to be the correct value the teacher got. The correct method was to find the diagonal distance to calculate the diagonal force.
