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.

Click on the picture below to try this simulation. Set the variables and click start. Watch as the graphs of displacement, velocity and acceleration are drawn. You will need java to run the simulation.

An explanation of heat loss from liquids in a vacuum flask. The Physics Classroom. Paper 2 is made up of questions with several parts that need written answers.

.

The unit of force is the newton N. We can't say because there is insufficient information. A direction is required before we can describe the force properly. Force is a vector close vector A vector describes a movement from one point to another. A vector quantity has magnitude size and direction.

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

Different materials have different latent heats. Vector Scale Diagrams from mr mackenzie on Vimeo. BBC News: Science. Refraction of light Refraction occurs when waves travel from one material to another. Use the next button or follow links in the left sidebar to progress through the topic. Current, Voltage and Resistance in series and parallel circuits. It carries significant risks including radiation, extreme temperatures, and high-speed impacts but these can be managed with technological solutions. By rotating at the same rate as the Earth, the satellite always appears to sit in the same point in our sky. By considering motion in horizontal and vertical directions, we can predict their path. Whole unit notes — thanks to Mr Noble for sharing these. Practical electrical and electronic circuits. Try these relative velocity problems. Refraction of light. Video Conductors and insulators.

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.

You can also create your own files and save them so that you can open them in school with Microsoft Office. They can be used to show acceleration and to work out displacement. Vectors and scalars. By considering motion in horizontal and vertical directions, we can predict their path. SQA National 5 Physics. AC and DC Electricity. They require different amounts of energy to change state between solid, liquid and gas. 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. How do you find exoplanets? This article gives an introduction to ac electricity. Refraction of light Refraction occurs when waves travel from one material to another. This short video shows a night-time re-entry over Mexico, with the orbiter on its way to land at the Kennedy Space Centre.
