Lecture 3 The Physics of Objects in Motion
... Falling Objects and Air Resistance • On Earth, air-resistance must be considered for falling objects. • As falling speed increases so does the opposing force of air-resistance. Net force (ΣF) = Weight – Air-resistance ...

... 4-1: Three students can all pull on the ring (see sketch) with identical forces of magnitude F, but in different directions with respect to the +x axis. One of them pulls along the +x axis with force F1 as shown. What should the other two angles be to minimize the magnitude of the ring’s acceleratio ...

Newton`s Laws/ Simple Machine Notes
... Velocity (v) – includes speed of an object and the direction of its motion Q: what is the difference between speed and velocity? A: Velocity includes directions where speed does NOT. Acceleration (a)- rate of change of velocity Acceleration occurs when an object changes speed, its direction, or both ...
