Practice Problem Set F=ma FORCE = MASS x ACCELERATION Plug in the given values for Force/Mass/Acceleration to solve. Remember, mass is in kg - - force in in N (newtons) - - acceleration is in m/s 2
In this chapter, we get some practice applying Newton’s laws to various physical problems. We do not introduce any new laws of physics. Solving F net = ma problems with multiple bodies Problem: A mass m 1 is pulled up a frictionless incline by a string over a pulley and a hanging mass m 2. We know m 1, m 2, and the angle . We seek :
F is applied to a system, the kinetic energy and the momentum undergo change according to the following equations: ~p = ~p 2 ~p 1 = X F~ t K = K 2 K 1 = X ~F ~s 1.2 Relationship Between Kinetic Energy and Momentum As you can see from the above equation, the P~ F (the net force) forms a rela-tionship between the change in momentum and the change ...
∴ only one equation to solve: p initial = p final In a perfectly inelastic collision, objects stick together after collision → treat the two objects as a single object after collision: p final = (m 1+m 2) v final • Most collisions are inelastic. • "Perfectly inelastic collisions" usually involve easily deformed objects e.g. wet clay ...
This textbook covers all the standard introductory topics in classical mechanics, including Newton’s laws, oscillations, energy, momentum, angular momentum, planetary motion, and special relativity.
