Physics for Scientists & Engineers & Modern Physics, 9th Ed

The nuclear force does not affect electrons, enabling energetic electrons to serve as point-like probes of nuclei. The charge independence of the nuclear force also means that the main difference between the n–p and p–p interactions is that the p–p potential energy consists of a superposition of nuclear and Coulomb interactions

3.4 Projectile Motion – College Physics

Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory.The motion of falling objects, as covered in Chapter 2.6 Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no …

Center of mass (video) | Khan Academy

If the center of mass is there, and let's say the mass of this entire ruler is, I don't know, 10 kilograms. This ruler, if a force is applied at the center of mass, let's say 10 Newtons, so the mass of the whole ruler is 10 kilograms. If a force is applied at the center of mass, this ruler will accelerate the same exact way as would a point mass.

Fig. 7(c) plots the simulated and experimental vertical velocities of the ball in the mill at 70% critical speed. Because there is only one ball in the mill, there are three states in which the ball exists: in contact with the mill, in flight, or in collision with the mill shell. It is easy to distinguish the three states in Fig. 7(c).
