ASTA01H3 Lecture Notes - Lecture 1: Critical Role, Planetary System, Net Force
Document Summary
Kepler"s second law: as the planet moves around its orbit, it sweeps out equal areas in equal times. This in turn means that the planet moves a greater distance on the orbit when in perihelion contrary to when it is at aphelion. This law also implies that planet has its biggest orbital velocity at perihelion and smallest orbital velocity at aphelion. Kepler"s third law: more distant planets orbit the sun at slower average speeds, obeying the precise mathematical relationship: p2 yr = a3. The entire history and evolution of universe is the result of the interaction between matter and energy. These interactions can be described by a number of laws, rst expounded by. Newton devised three laws that are obeyed by all moving bodies. It also has the direction of movement built within it. Acceleration: rate of change of velocity with time.
