Chapter 4 Forces and Newton’s Laws of Motion
... How does the friction between the mass and the table “know” how much force will EXACTLY balance the gravity force pulling the mass down the ramp? As you slowly put the mass on the ramp, the ramp compresses & stretches along the ramp as gravity tries to slide the mass down the ramp. When you let go, ...

... When the fly hit the truck, it exerted a force on the truck (only for a fraction of a second). So, in this time period, the truck accelerated (backward) up to some speed. After the fly was squashed, it no longer exerted a force, and the truck simply continued moving at constant speed. Follow-up: Wha ...

... 29. In crystals of the salt cesium chloride, cesium ions Cs+ form the eight corners of a cube and a chlorine ion Cl- is at the cube’s center. The edge length of the cube is 0.4 nm. The Cs+ ions are each deficient by one electron (and thus each has a charge of +e), and the Cl- ion has one excess ele ...

Newton`s Second Law
... Sir Isaac Newton1 put forth many important ideas in his famous book The Principia. His three laws of motion are the best known of these. The first law seems to be at odds with our everyday experience. Newton’s first law states that any object at rest that is not acted upon by outside forces will rem ...

... Consider a body on which no net force acts. If the body is at rest, it will remain at rest. If the body is moving with a constant velocity, it will continue to do so. Inertial frame of reference: A non-accelerating frame of reference in which Newton’s first law is valid. ...

Provide graphs of your movement as a function of time – displacement-t, velocity-t, acceleration-t, net force-t, kinetic energy-t, power-t. What is the maximum power that you provide? – OK, please finish this if you can for Monday’s class, but ...
