Chapter 10 – Rotation and Rolling
... Translation: body’s movement described by x(t). Rotation: body’s movement given by θ(t) = angular position of the body’s reference line as function of time. Angular displacement: body’s rotation about its axis changing the angular position from θ1 to θ2. ...

Chapter 4 - Newton`s Laws of motion
... • The bus is accelerating with respect to the earth and in not a suitable frame of reference for Newton’s 1st law. A frame of reference in which Newton's 1st law is valid is called an inertial frame of reference. The earth is at least approximately an inertial frame of reference, but the bus is not. ...

Chapter 4
... An object in equilibrium has no net external force acting on it, and the second law, in component form, implies that ΣFx = 0 and ΣFy = 0 for such an object. These two equations are useful for solving problems where the object is at rest or moving at constant velocity. ...

Circular and Centripetal Motion
... As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the centripetal force required for circular motion. ...

static friction - University of Toronto Physics
... Last day I asked at the end of class: Does friction always slow things down? ANSWER: No! Kinetic friction does oppose the relative motion of two surfaces. If the one of these surfaces is stationary, then it will tend to slow down the moving object. Can friction ever speed things up? ANSWER: Yes! St ...
