Semi-Major Axis - Ellipse
In geometry, the major axis of an ellipse is the longest diameter: a line (line segment) that runs through the center and both foci, with ends at the
Escape velocity is the speed at which the kinetic energy plus the gravitational potential energy of an object is zero. It is the speed needed to
Semi-Major Axis - Hyperbola
The semi-major axis of a hyperbola is, depending on the convention, plus or minus one half of the distance between the two branches. Thus it is the
Potential energy is the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system. The amount
In science and engineering, the weight of an object is usually taken to be the force on the object due to gravity.
In Newtonian physics the weight is
