書摘/試閱
A common AP question, then, gives momentum ofan object as a function oftime, and asks you to take the derivative to Fmd the force on the object.
Its also useful to understand this calculus graphically Given a graph ofmomentum vs.time, the slope of the tangent to the graph gives the force at that point in time.Given a graph of force vs.time,ut～eerarea under that graph is impulse, or change in momentum during that time interval.
Motion of the Center of Mass
The center of mass ofa system ofobjects obeys Newtons second law.Two common examples might illustrate the point:
(1) Imagine that an astronaut on a spacewalk throws a rope around a small asteroid, and then pulls the asteroid toward him.Where will the asteroid and the astronaut collide?
Answer: at the center ofmass.Since no forces acted except due to the astronaut and asteroid, the center of mass must have no acceleration.The center of mass started at rest, and stays at rest, all the way until the objects collide.
(2) A toy rocket is in projectile motion, so that it is on track to land 30 m from itslaunch point.While in the air, the rocket explodes into two identical pieces, one of which lands 35 m from the launch point.Where does the first piece land?
Answer: 25 m from the launch point.Since the only external force acting on therocket is gravity, the center ofmass must stay in projectile motion, and must land 30m from the launch point.The two pieces are ofequal mass, so if one is 5 m beyondthe center ofmasss landing point, the other piece must be 5 m short of that point.
Finding the Center of Mass Usually the location of the center of mass (cm) is pretty obvious …… the formal equationfor the cm of several objects is Multiply the mass ofeach object by its position, and divide by the total mass M, and voila,you have the position of the center of mass.What this tells you is that the cm of several equal-mass objects is right in between them; if one mass is heavier than the others, the cmis closer to the heavy mass.
Very rarely, you might have to Find the center ofmass ofa continuous body (like a baseball bat) using calculus.The formula is Do not use this equation unless (a) you have plenty of extra time to spend, and (b) you know exactly what youre doing.In the highly unlikely event its necessary to use this equation to find a center of mass, you will usually be betrer offjust guessing at the answer and moving on to the rest of the problem.(If you want to find out how to do such a problem thoroughly, consult your textbook.This is not something worth reviewing if you dont know how to do it already).
