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.

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.

.

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. The motion of all objects that are speeding up, slowing down or changing direction close direction Information to give the direction of travel, or the direction of a force, for example, a speed of 20 m s -1 to the left, or a force of 15 N to the right. In Physics, we use Newton's Second Law to explain different types of motion and to do calculations involving force, mass close mass The amount of matter an object contains.

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. Measurement and analysis of current and voltage in simple circuits allows us to formulate rules and predict unknown values. Power is a measure of the rate of energy transfer and relates to the current and voltage for an electrical circuit. Conductors and insulators. Video Conductors and insulators.

This is quite handy, since it would be a nuisance if we had to move dish aerials to follow the location of a satellite broadcasting our TV signals. Cosmology Observation of the universe has improved our understanding of its age, its size and the composition of stars. This article gives an introduction to ac electricity. Can you use the kinetic theory of gases to describe the pressure-temperature, pressure-volume or volume-temperature relationships? Waves in the electromagnetic spectrum can all travel through a vacuum at the speed of light. Curved reflectors are often used to produce a strong beam of energy in one direction. By considering motion in horizontal and vertical directions, we can predict their path. The second clip looks at the way skydivers use forces to land safely. By considering motion in horizontal and vertical directions, we can predict their path. Heat transfers and the vacuum flask. Nuclear radiation Alpha, Beta and Gamma radiation all have different properties and effects. Here is a video guide to drawing a vector scale diagram to find displacement. Refraction of light takes place in many places, including lenses and prisms. Velocity-time graphs are used to describe the motion of objects which are moving in a straight line.

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.

The video below is designed to show you what the view from a geostationary satellite might look like. Projectile motion Projectiles and satellites move in curved paths due to the effects of gravitational force. Velocity-time graphs are used to describe the motion of objects which are moving in a straight line. Using transistors as switches. I might actually have a chance for an A in Physics! Paper 1 is a multiple choice paper. Space exploration has benefited many areas of science and technology including satellites and GPS. Newton's Laws. Specific heat capacity. How to do half-life calculations pdf. It can be calculated by dividing the change in velocity by the total time. Measurement and analysis of current and voltage in simple circuits allows us to formulate rules and predict unknown values. Properties of matter. This high temperature during re-entry is the reason those special black tiles are needed on its underside.
