6 Elective Homework Getting Started Success involves doing many kinds of problems which help improve your knowledge and understanding of the ideas in the course and your ability to solve problems. To get started we will look at a general method for tackling problems. General Method for Solving Problems. Any numerical problem in Physics can be solved using the following steps: Read the question carefully. Find out exactly what is being asked. Extract the key data. Select the correct equation. Substitute the data into the equation and find the missing variable. Give the answer and correct unit. Example How far does a cyclist travel in 26 seconds if she is travelling at a constant speed of 8 metres per second? Solution Read the question carefully Find out exactly what is being asked Extract the key data Distance (how far) time = 26 seconds speed = 8 metres per second Select the correct equation distance = speed x time Substitute data into equation d = 8 x 26 Give the answer and correct unit d = 208 m Page 6
7 Usual Layout d =? v = 8 m/s t = 26 s d = v x t = 8 x 26 = 208 m All numerical questions in the following homework exercises should be carried out in this way. No marks will be awarded for an answer given without the working being shown. Helpful Hint Always watch the units in an equation. They may need to be converted before being put into an equation. e.g. 3 ma = A = 3 x 10-3 A 6 km = 6000 m = 6 x 10 3 m Page 7

14 Summary Notes Density Density is the mass per unit volume of a substance. An object will float in the liquid it is placed in if it is less dense than that liquid and sink if it is more dense. The formula used to calculate density is: The units of density are grams per cubic centimetre (g/cm 3 ) To find the density of any substance you must find its mass and volume then use the density formula. To find the volume of a regular shaped object such as a cube or cuboid the following method is used: Volume = length x breadth x height = l x b x h Page 14
15 To find the volume of an irregular shaped object the displacement of water is used, as illustrated in the diagrams below. Diagram 1 shows the water being displaced in a measuring cylinder and diagram 2 shows how an overflow vessel can be used. Diagram 1 Diagram 2 When liquids of different densities are added together in the one container they will separate out to form a density ladder. This is because the liquids are all different densities. The most dense liquid will go to the bottom and the least dense to the top. Where other objects sit in the density column depends on how dense the objects are. Page 15
16 Kinetic Theory The following pictures represent the particle arrangement for solids, liquids and gases. The Kinetic Theory of Gases describes a gas as a large number of small particles, all of which are in constant, random motion. It helps explain properties of gases such as volume, temperature and pressure. The pressure of a gas is caused by the particles colliding with the walls of the container it is in. The temperature of a gas depends on the kinetic energy of the gas particles. Pressure is measure in units called Pascals (Pa). Temperature is measured in Degrees Celsius ( C) A Bourdon Gauge is used to measure the pressure of a gas. Page 16
17 Gas Laws There are three gas laws: Boyle s Law, Gay Lussac s Law and Charles Law. Boyle s Law explains that as the volume of a fixed mass of gas increases, the pressure decreases provided the temperature of the gas remains constant. This is because when the volume increases the particles move further apart and collide less frequently with the walls of the container. (See diagram below). Boyle s Law Page 17
18 Gay Lussac s Law explains that as the temperature of a fixed mass of gas increases the pressure increases provided the volume remains constant. This is because as the temperature increases the particles gain kinetic energy and move faster. They collide with the walls of the container more often and with greater force, thereby causing the pressure to increase. (See diagram below). Charles Law states that as the volume of a fixed mass of gas increases the temperature increases provided the pressure of the gas remains constant. This is because as the temperature increases the particles gain kinetic energy and move faster. They collide with the walls of the container more often and with greater force. The volume must increase to give a greater surface area to keep the pressure constant. (See diagram below). Gay Lussac s Law Charles Law Page 18
