... Now for the frictional force. As for its direction, the direction is in whichever direction hinders the relative motion of the two surfaces. Often, when the instructor gets sloppy, s/he will say that the frictional force acts in the direction opposite the motion. This is usually true, but there is a ...

... e.g.2. A particle, A, of mass 0·6 kg, is held at rest on a smooth table. A is connected by a light, inextensible string, which passes over a smooth fixed pulley at the edge of the table, to another particle, B, of mass 0·4 kg hanging freely. The string is horizontal and at right angles to the edge ...

... secs, speeding it up to a final speed v. If the applied force were only 1/2 F, how long would it have to be applied to reach the same final speed? In the first case, the acceleration acts over time T = 4 s to give velocity v = aT. In the second case, the force is half, therefore the acceleration is ...

... In other words inertia and mass are proportionally related. More mass = more inertia Inertia is NOT a force. Forces are needed to overcome inertia Newton (1643-1727) expanded on this concept of inertia and developed his 3 laws of motion. These three laws are the foundation for classical mechanics ( ...
