... Angular Momentum of a Particle If you grab onto a pole while running, your body will rotate about the pole, gaining angular momentum. We’ve used the linear momentum to solve physical problems with linear motions, the angular momentum will do the same for rotational motions. Let’s consider a point-l ...

... everything in the Universe, this is a little limiting. In this section, we take a small step forwards: we will describe the dynamics of N, interacting particles. The first thing that we do is put a label i = 1, . . . , N on everything. The ith particle has mass mi , position xi and momentum pi = mi ...

1 Newton`s Second Law
... Read this passage from the text and answer the questions that follow. Acceleration and Weight Newton’s second law of motion explains the weight of objects. Weight is a measure of the force of gravity pulling on an object of a given mass. It’s the force (F) in the acceleration equation that was intro ...

Time and Energy, Inertia and Gravity
... Referring now to figure 1, we can compare the relativistic motion of a particle to the Newtonian motion when a constant force is applied. Whereas in Newtonian motion the velocity increases without limit, in relativistic motion the velocity increases asymptotically as the object approaches the speed ...

12.3 Velocity and Acceleration
... Velocity and Acceleration As an object moves along a curve in the plane, the coordinates x and y of its center of mass are each functions of time t. Rather than using the letters f and g to represent these two functions, it is convenient to write x = x(t) and y = y(t). So, the position vector r(t) ...

Are You suprised
... In this part of the lab, you will vary the Force by changing the weight hanging over the edge of the table. For each trial, you will use a different amount of suspended (hanging) mass. Using the formula W=mg, you can calculate the force (weight) that is doing the pulling. For these calculations, m i ...
