Appendix B: On inertial forces, inertial energy
... frame. When the particle is compelled to move with the noninertial frame’s acceleration, it starts to resist the change in its inertial motion and exerts a real inertial force on the mover that accelerates it. What also might contribute to a better understanding of the status of inertial forces is t ...

Newton`s Second Law - Philadelphia University
... SI system: In the SI system of units, mass is a base unit and weight is a derived unit. Typically, mass is specified in kilograms (kg), and weight is calculated from W = mg. If the gravitational acceleration (g) is specified in units of m/s2, then the weight is expressed in newtons (N). On the earth ...

... 1. Consider a point on a bicycle wheel as the wheel turns about a fixed axis, neither speeding up nor slowing down. Compare the linear and centripetal accelerations of the point. a Both are zero. b Only the centripetal acceleration is zero. c Only the linear acceleration is zero. d Neither is zero. ...

Quick notes Giancoli #1
... Chapter 8 Notes in a nutshell 8-1 Rotational motion: 1. A rigid object is an object with a definite shape that doesn’t change. 2. Purely rotational motion means that all points in an object moves in circles and the centers all lie on one line called the axis of rotation 3. To calculate the angular p ...

Inward “Centrifugal” Force on a Helium
... This leads to the erroneous conclusion that this force, as its own (Latin) name suggests, must be always directed outward. We propose here to analyze the motion of a helium balloon placed inside a car that is traveling around a curve. The balloon is fixed to the rear seat of the car by means of a li ...
