The linear momentum of an object is defined to be equal to its mass times its velocity. One meter is about equal to 3.3 feet or 1.1 yards. Used in determining the radius of the circle that most closely approximates the shape of the arc. It is a vectored quantity with both magnitude and direction. The color is normally white or grey.
Potential energy is stored in the interaction of an object with another object.
Gravitational potential energy is a type of potential energy. Energy, linear momentum, and angular momentum are examples of quantities associated with all systems. Reflectorized RPM's come in many different colors and are used to delineate travel lane lines and outside boundaries. The angular momentum of an object is defined in relation to some point, the reference point. The velocity and radius of an object are measured from the reference point.
