Consider what happens if the masses of two colliding objects are more similar than the masses of a football player and Earth—for example, one car bumping into another, as shown in Figure 1. Both cars are coasting in the same direction when the lead car (labeledm2) is bumped by the trai...
It is very important to involve the concept of momentum while discussing the impact of force. For example, the bullet thrown by our hand may not hurt a person, but when the bullet is shot using a gun, it may kill a person. Though the mass of the bullet is the same in both cases, ...

No information is given regarding direction, and so we can calculate only the magnitude of the momentum,p. (As usual, a symbol that is in italics is a magnitude, whereas one that is italicized, boldfaced, and has an arrow is a vector.) In both parts of this example, the magnitude of...
Example: a spinning wheel – - The wheel has mass and every part of the wheel is moving when the wheel spins. - Particles far from the center of the wheel are . . . moving the fastest and have the most linear momentum. - The angular momentum of the wheel comes from . . . the or...
3、In physics, moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia andmomentum.(在物理学中,运动的物体有两个特征与理解能量系统动力学相关:惯性和动量。) 4、You can call that ancestor-worship if you wish, but it gives to the paper an astonishin...
In Physics, Momentum and Inertia are related. In the battle for mind-share, they are as well. If I have an idea, and I can demonstrate, in some small example, how useful that idea can be, then my idea will start to move people. I will say "we can succeed" and they will say "...
Physics 1D03 - Lecture 25 Example Rain is falling vertically into an open railroad car which moves along a horizontal track at a constant speed. The engine must exert an extra force on the car as the water collects in it (the water is initially stationary, and ...
Symmetry is an important topic for maths and physics. Symmetry is important for many branches of mathematics including geometry (see this page) and group theory (see this page). Its importance can become apparent in unexpected places, for example, solving quintic equations. We say that an ...
Example 1. Calculating Angular Momentum of the Earth Strategy No information is given in the statement of the problem; so we must look up pertinent data before we can calculate L = Iω. First, according to Figure 1, the formula for the moment of inertia of a sphere is Figure 1. Some ...
