‘O’-Level Physics 5059 Compulsory Definitions List V1 Term / Phrase Definition C1: Physical Quantities‚ Units and Measurement Scalar quantities Scalar quantities are physical quantities that have magnitude only. Vector quantities Vector quantities are physical quantities that have both magnitude and direction. C2: Kinematics Speed Speed is the rate of change of distance travelled. Velocity Velocity is the rate of change of displacement. Uniform acceleration Uniform acceleration is a constant rate

Physics can simply be defined as the science that studies the mechanics of matter‚ motion‚ energy‚ and force. Dance in my opinion is a type of performance categorized as a form of art that involves the mind‚ body‚ soul‚ and a little something called physics. Dancing is a personal favorite hobby of mine‚ but I’ve never really considered the physics side of dancing which seems odd considering all the different movements and techniques that involve many principles of physics such as rotational inertia

BUOYANCY PHYSICS Student: Instructor: Criteria : Design Introduction The purpose of this experiment to find the effect of temperature on buoyancy . Backround Information Buoyancy (also known as the buoyant force) is the force exerted on an object that is wholly or partly immersed in a fluid. The symbol for the magnitude of buoyancy is B or FB As a vector it must be stated with both magnitude and direction. Buoyancy acts upward for the kind of situations encountered in everyday experience

Energy Energy can neither be created or destroyed‚ only changed into different forms. Energy is only useful when it can be converted into different forms. Energy is often dissipated - spread out and lost. 9 types of energy: Thermal (heat) - flows from hot to cold objects Kinetic (movement) - anything that is moving has this Light - from the sun‚ light bulbs et cetera Elastically potential - when things are stretched Gravitational potential - anything that can fall Electrical - whenever

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a or P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”. Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid. The amount of force pushing upward on the object is equal to the density of the fluid (Ï) times the acceleration

Energy: the ability to do work. Work= force x displacement. Power=energy/time Power is measured in watts or horsepower. Joules/sec=watts 1hp=746w=1kw Basal metabolic rate 2000kcal/day= 100w Batteries store energy in chemical form. They release energy by pumping electrons’ through wires from the minus pole to the plus pole. Devices inbetween convert this energy to another form‚ Efficieny- e.motor=85%‚ combustion= 20% Hydrogen is not a source of energy but a means of transportation Types of energy:

Physics (Thorpe Park Trip) Report: On Monday 8th October our physics class went on a physics trip to Thorpe Park to look at the different ways in which a roller coast works. This report will be looking at the G forces acting on rides‚ the launching systems and breaking systems. The particular rollercoaster which I have picked to look into more detail in is “Stealth” which is located in Thorpe Park. Stealth: Stealth was originally designed by Werner Stengel. Stealth reaches a height of 205 feet

Contextual Outline: ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Modern 9.3 MOTORS ANDis geared to using electricity. industrialised society GENERATORS Electricity has characteristics that have made it uniquely appropriate for powering a highly technological society. There are many energy sources that can be readily converted into electricity. In Australia‚ most power plants burn a fuel‚ such as coal‚ or use the energy of falling water to generate electricity on a large scale. Electricity is also relatively
