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.

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 blog post gives you some more information about nuclear fission.

.

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.

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.

Newton's Laws. Specific heat capacity When an object is heated, the change in temperature is related to energy, mass and the specific heat capacity of the material it is made of. Set the variables and click start. Space exploration has benefited many areas of science and technology including satellites and GPS. The professor from the brilliant periodic videos site has a clip about Lord Kelvin and the temperature scale named after him. The shiny backgrounds behind the bulb of a car headlamp, torch or halogen spotlight are examples of curved reflectors. Okay thanks anyway! Notify me of new posts by email. Heat transfers and the vacuum flask. Waves in the electromagnetic spectrum can all travel through a vacuum at the speed of light. Specific latent heat. Whole unit notes — thanks to Mr Noble for sharing these! Electrical current is electrical charge transferred in a particular time. There are links to the answers next to the links to the questions.

If the number of electrons is equal to the number of protons then the atom is uncharged and is electrically neutral.

The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another. Paper 1 is a multiple choice paper. Check this blog post to find out how you can get free physics revision software for home use only. A geostationary satellite is not actually stationary. Scalars have a size, while vectors have both size and direction. This short video shows a night-time re-entry over Mexico, with the orbiter on its way to land at the Kennedy Space Centre. Practical electrical and electronic circuits Measurement and analysis of current and voltage in simple circuits allows us to formulate rules and predict unknown values. Or maybe someone else has produced a set? SQA National 5 Physics. Refraction of light Refraction occurs when waves travel from one material to another. Refraction of light.
