These papers and solutions are reproduced to support SQA qualifications on a non-commercial basis according to SQA conditions of use. The sections below contain links to revision notes, PowerPoint slides and extra questions to test your readiness for assessments in each of the units.

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. 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.

Current can be a. You can view a larger version by clicking on the image below. Notify me of new posts by email.

When work is done on an object it may also lead to energy being transformed to the object in the form of gravitational potential energy close potential energy Potential energy, in this instance, is associated with gravitational potential energy - the energy gained while rising a certain height. Measured in joules J. For example, the cable car gained potential energy as it rose into the mountains. Gravitational potential energy is the energy an object has by virtue of its position above the surface of the Earth. When an object is lifted, work is done. When work is done in raising the height of an object, energy is transformed as a gain in the gravitational potential energy of the object. When this force equal to the weight mg , but upwards is applied to the suitcase over the distance h :. In this guide. Conservation of energy Energy transformed due to frictional forces Kinetic energy Gravitational potential energy Example Conservation of kintetic and potential energy. Gravitational potential energy.

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. Practical electrical and electronic circuits.

Velocity-time graphs Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. Here is a short video about projectile motion. An explanation of heat loss from liquids in a vacuum flask. The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another. Video Heat transfers and the vacuum flask. Specific heat capacity. Nuclear radiation Alpha, Beta and Gamma radiation all have different properties and effects. Links BBC Science. Paper 1 is a multiple choice paper. This high temperature during re-entry is the reason those special black tiles are needed on its underside.

We use words like acceleration close acceleration The rate of change in speed or velocity is measured in metres per second squared. Forces acting on a body cause the motion of that body to change. Newton's First Law and Second Law explain the different types of motion.

Newton's Laws. Velocity-time graphs are used to describe the motion of objects which are moving in a straight line.

Why does a metal wire conduct electricity while the plastic sheath does not? Projectiles and Satellites. Notify me of new posts by email. Current can be a.
