1.1 GRAVITY AND GRAVITATIONAL FIELDS 1.1.1 Define weight as the force on an object due to a gravitational field. Weight is the force experienced by an object due to the presence of a gravitational field. This force is directly related to the strength of the gravitational field acting on an object and the mass of that object. m = mass‚ g = acceleration due to gravity m = mass‚ g = acceleration due to gravity Fg = mg Fg = mg 1.1.2 Explain that a change in gravitational

Long Run Equilibrium (A) Firm and Industry: A competitive market is made up of a large number of firms with complete freedom of entry. Such firms together are called competitive industry. An industry can be defined as a group of firms producing homogeneous products with freedom of entry and exit and which earn only normal profits. Hence the concept of an industry is applicable only under competitive conditions. There is no fixed size of an industry though the analytical stability of an industry

ceiling create shortage. How to overcome it? According to the book “Economic Theory in the Malaysian Context”‚ the definition of price ceiling is a legally established maximum price a seller can charge. It means that the price is lower than the equilibrium market price and it cannot go above the ceiling price. The reason that government imposes ceiling price on item such as beef‚ flour‚ sugar and many more is because to ensure that consumers are able to buy these goods at a reasonable price thus prevent

chemical equilibrium is already achieved. A reaction is said to be at equilibrium when the following conditions exist. 1. 2. 3. Several factors such as temperature‚ concentration and pressure affects the rate of reaction which can cause an effect in the chemical equilibrium. A general rule is used to predict the direction in which an equilibrium reaction will move which is called the Le Chatelier’s Principle. It states that if an external stress is applied to a system at equilibrium‚ the system

Cosmology By: Jarrett Leuta-Douyere A New Look at Sports Growing up in a family filled with athletic desire to be great at whatever sport we would participate in and understanding simple physics in Cosmetology‚ I never realized how much physics comes into play when playing sports. We don’t call it physics when were playing‚ football‚ basketball‚ baseball because it’s just a natural feeling when were throwing a ball or trying to tackle someone. When we began to learn about Newton’s law of Gravity
