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.

Using transistors as switches.

If the number of electrons is equal to the number of protons then the atom is uncharged and is electrically neutral. Ionisation close ionisation Process by which electrons can be added or removed from an atom to create an ion. An atom's charge can only change through gaining or losing electrons. Protons cannot be added or removed because they are bound up with neutrons in the nucleus. Electrons can be lost because an ionising radiation something that you will study later in this chapter comes close to or collides with the atom and forces the electron away from the atom.

Velocity-time graphs. Many thanks Amandeep Reply. The potential difference or voltage of a supply is a measure of the energy given to the charge carriers in a circuit. The Physics Classroom. Refraction of light. By considering motion in horizontal and vertical directions, we can predict their path. Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. Alpha, Beta and Gamma radiation all have different properties and effects. Sorry for taking so long. Charge and Current.

Electrical charge carriers.

Vectors and scalars Scalars have a size, while vectors have both size and direction. In places where the original slide is animated, you will need to read several pages in a row to see the full slide contents. The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another. Graphs of motion Click on the picture below to try this simulation. Radiation doses are mentioned in this article in The Guardian newspaper. Refraction occurs when waves travel from one material to another. Paper 2 is made up of questions with several parts that need written answers. The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another. Projectiles and satellites move in curved paths due to the effects of gravitational force. By rotating at the same rate as the Earth, the satellite always appears to sit in the same point in our sky. Many thanks Amandeep Reply. Electrical charge carriers. Curved reflectors are often used to produce a strong beam of energy in one direction.
