Newton`s Laws
... According to Newton's third law, every force is accompanied by an equal and opposite reaction force. The reason that these forces do not cancel each other is ____. a. the action force acts for a longer time period b. the two forces are not always in the same direction c. one of the two forces is gr ...

... A 5-kg mass with initial velocity 20 m/s slides along a frictionless horizontal surface then up a frictionless ramp (2 m long and at an angle 30 degrees to the horizontal) and onto a second horizontal surface. The block slides over a rough surface 15 m in length (µk = 0.4) before moving again on a f ...

determination of the acceleration of an elevator.
... DETERMINATION OF THE ACCELERATION OF AN ELEVATOR. INTRODUCTION: In order for an object to accelerate, there must be a net force acting on it. We know that the direction of the acceleration will be in the same direction as the direction of the net force. The equation for Newton’s 2nd law is F = ma o ...

For more complicated shapes, just approximate the volume with a simpler shape. Force of Drag This one is sligh ...
