Connecting Force and Motion, and Newton`s First Law of Motion
... in an instant what would happen to you? Also, what would happen to you if you stopped in an instant? A. Let’s first examine what happens when a jet or starship turns on its engine: 1. The hot air produces thrust for the jet, and fusion reaction pushes gas and radiation backward propelling the starsh ...

Chapter 5: Applying Newton`s Laws
... IDENTIFY the relevant concepts: You must use Newton’s first Law for any problem that involves forces acting on a body in equilibrium. Remember that “equilibrium” means that the body either remains at rest or moves with constant velocity. For example, a car is in equilibrium when it’s parked, but als ...

... Galileo (1564-1642) noticed that larger (more massive) objects resisted changes in their motion. For example a cannon ball rolling across the ground was harder to stop than an apple rolling across the ground. He coined the term inertia to describe this. Inertia is the natural tendency of an object ...

Solution
... If the rider is riding at a constant speed, then the positive work input by the rider to the (bicycle + rider) combination must be equal to the negative work done by gravity as he moves up the incline. The net work must be 0 if there is no change in kinetic energy. (a) If the rider’s force is d ...
