... A particle of mass m has a velocity v relative to the Earth as it traverses the solar system at the orbital radius of the Earth around the Sun. The initial velocity v is the value far enough outside the gravitational well of Earth that the Earth’s gravitational effects need to be accounted for in wh ...

... Also, vi is the initial velocity for a time step and si is the initial position for a time step. If we let the time step be a real number t rather than a tiny infinitesimal quantity dt, then we have changed a differential equation into a finite difference equation. This is Euler’s method. It uses t ...

... A friction force is… (A) a contact force that acts parallel to the contact surfaces. (B) a contact force that acts perpendicular to the contact surfaces. (C) a scalar quantity since it can act in any direction along a surface. (D) always proportional to the weight of an object. (E) always equal to t ...
