differs from that of mid-latitude cyclonic storms‚ such as nor’easters and European windstorms‚ which are fueled primarily by horizontal temperature contrasts. The strong rotating winds of a tropical cyclone are a result of the (partial) conservation of angular momentum imparted by the Earth’s rotation as air flows inwards toward the axis of rotation. As a result‚ they rarely form within 5° of the equator.[1] Tropical cyclones are typically between 100 and 4‚000 km (62 and 2‚500 mi) in diameter.The term

Physics HSC Notes Space 1. Earth has a gravitational field that exerts a force on objects both on it and around it. K1 Define weight as the force on an object due to a gravitational field. Mass is the amount of matter within an object‚ measured in kg Weight is the force of gravity acting on an object’s mass measured in newtons (N). Weight is a force thus a vector quantity. K2 Explain that a change in gravitational potential

A Hohmann transfer orbit is an elliptical orbit used to switch from one circular orbit to another on the same plane. The Hohmann transfer is based upon two main concepts: conservation of angular momentum and conservation of total mechanical energy. It is these two concepts and their corresponding equations that allow one to evaluate the velocity change needed to head on the Hohmann transfer orbit. However‚ the Hohmann transfer model does have

GRAVITATION Kepler’s Laws Towards the end of the sixteenth century‚ Tycho Brahe collected a huge amount of data giving precise measurements of the position of planets. Johannes Kepler‚ after a detailed analysis of the measurements announced three laws in 1619. 1. The orbit of each planet is an ellipse which has the Sun at one of its foci. 2. Each planet moves in such a way that the (imaginary) line joining it to the Sun sweeps out equal areas in equal times. 3. The squares of the periods

UNIT 1 Modern Physics 1.1 CLASSICAL PHYSICS Newtons laws of motion are the basis of the most elementary principles of classical physics. Equations based on these laws are the simplest and they are suitable for solution of simple dynamical problems‚ such as the motion of macroscopic bodies‚ Lagranges equations‚ Hamiltons equations and Hamiltons principle are also fundamental principles of classical mechanics‚ because they are consistent with each other and with Newtons laws of
