2 Friction and Gravity
... Static Friction Four types of friction are shown in Figure 6. The friction that acts on objects that are not moving is called static friction. Because of static friction, you must use extra force to start the motion of stationary objects. For example, think about what happens when you try to push a ...

Line Integrals
... In this Workbook you will learn how to integrate functions involving vectors. You will learn how to evaluate line integrals i.e. where a scalar or a vector is summed along a line or contour. You will be able to evaluate surface and volume integrals where a function involving vectors is summed over a ...

... you can correct the egregiously inaccurate assumptions later. How dense is wood? Once again, use the guerrilla method: Wood barely floats, so its density is roughly that of water, ρ ∼ 1 g cm−3 . A bill, which has volume v ∼ 1 cm3 , has mass m ∼ 1 g. And 107 cm3 of bills would have a mass of 107 g = ...

... applies only if the rate of rotation is changing. The direction makes sense, because if the angular velocity is increasing, then dω dt is in the direction of the rotation and the inertia of the particle will resist this change. The effective force is therefore in the opposite direction. The second t ...

When the barrel of oil has been rolled up the ramp to the platform level it will have a potential energy of: 180 kg x 9.81 m/s2 x 1 m = 1766 Nm If there is no friction, then the work done by rolling the barrel up the ramp will be equal to the work output, that is 1766 Nm. If there is friction, then ...

This can only be done under some quite strict assumptions, but as it turns out, these assumptions are very close to being correct. Some of the equat ...
