The National 5 Physics exam is made up of two question papers. Paper 1 is a multiple choice paper. Paper 2 is made up of questions with several parts that need written answers. Vectors and scalars. Scalars have a size, while vectors have both size and direction. When adding vector quantities, it is possible to find the size and direction of the resultant vector by drawing a scale diagram. Velocity-time graphs. Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. They can be used to show acceleration and to work out displacement. Acceleration is the change in speed or velocity of an object over a certain time. It can be calculated by dividing the change in velocity by the total time. Newton's Laws. The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another.

This article gives an introduction to ac electricity. Energy The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another. I got them from Mr Noble.

Often these type of questions are the most challenging and can make a difference to gaining better grades. The key to writing a good answer is to recognise and be clear about what area of the course the question is based on. This involves a good and ready knowledge of the course content based on effective revision. For example, if a question asks you to: "Explain the increase in acceleration of a rocket as if takes off for the first kilometre of flight":. Note the gravitational field strength does not vary appreciably over the first km weight only changes due to decrease in mass so this would not be considered part of a correct answer. Explanation questions. Once clear on the question being asked, plan the structure of an answer by listing keywords which will help to gain marks. Write a coherent and possibly concise answer with logical progression of what variable makes changes to others. State or refer to any quantities that do not change. Sketch diagrams can be referred to as part of an answer.

Electrical charge carriers. Electrical current is electrical charge transferred in a particular time. Current can be a. Potential differences voltage.

Projectile motion Projectiles and satellites move in curved paths due to the effects of gravitational force. Curved reflectors are often used to produce a strong beam of energy in one direction. This is the type of answer you need to give in a question where you are asked to describe gas behaviour using the kinetic theory. Potential differences voltage The potential difference or voltage of a supply is a measure of the energy given to the charge carriers in a circuit. It carries significant risks including radiation, extreme temperatures, and high-speed impacts but these can be managed with technological solutions. Is this for the past paper booklets? The vehicle slows down as its kinetic energy is lost. In places where the original slide is animated, you will need to read several pages in a row to see the full slide contents. Vectors and scalars. This article gives an introduction to ac electricity.

When a wave or light ray moves from one medium to another its speed changes. The direction of the ray may also change.

Refraction of light takes place in many places, including lenses and prisms. If you are having difficulties with this, try reading this blog post. Or, if you have a Glow username and password, download a copy of Microsoft Office from the tile on your home page. The potential difference or voltage of a supply is a measure of the energy given to the charge carriers in a circuit. Waves in the electromagnetic spectrum can all travel through a vacuum at the speed of light. Electrical charge carriers Electrical current is electrical charge transferred in a particular time.
