A concise explanation of this trickiest of concepts.

Examples and questions demonstrating the difference between actual speed and relative speed. All answers included.

Resultant forces are explained and identified. Newton’s second law is introduced. There are examples of F=ma followed by a number of questions. Designed for the classroom and would work online. The answers are in a separate file.

The presentation describes the process of conduction on an everyday scale and then in terms of particles. True or False statement test at the end with answers. This resource could be expanded upon as a lesson in school. It has been designed as a home learning activity. It is 1 in a series of 4 about thermal energy transfer.

An introduction to turning forces. Calculation of moment. Balancing of moment. Questions based around balancing seesaws. All solutions included. Would work well for a new teacher or teacher out of subject. Classroom or online resource.

The KE equation is introduced. Example calculations and a st of questions(with answers).

From initial ideas of extension, definitions, calculations and gradients. All aspects of stretching springs are looked at.

Detailed description of the conditions for total internal reflection. Calculations and solutions included. Designed as an online resource, would also work in the classroom.

The basics of current in series and parallel circuits. The distribution of voltage in a circuit.

Gas pressure is described in terms of particles. It addresses what causes gas pressure, how temperature effects pressure and a change in volume and pressure. True or false quiz to assess learning at the end.

Characteristics of a reflection diagram from a plane mirror are identified. There is a set of data to graph. A gradient calculation is shown giving a result of 1 which matches the incident angle to the reflected angle which in turn supports the law of reflection. Comments on the reliability of the data are then made.

This lesson establishes the concept of mass ad its constant nature throughout the universe The constant gravity of Earth is established as well as other gravitational field strengths. The weight=massxgravity equation is introduced. There are practice calculations throughout as well as a statement test at the end. It would make a good home learning resource.

This resource links infra-red from the electromagnetic spectrum to thermal radiation and it’s key characteristics are identified. Data on absorption and reflection of different surfaces is listed and a graph plot is required. A conclusion is required about the effectiveness of each surface. This resource has been designed as a home learning resource but would also work in the classroom. It is 1 of a set of 4 pieces about thermal energy transfer.

This presentation introduces the ideas of current and voltage and the measurement of them. It has analogue meters to take readings from and then develops the ideas behind batteries and polarity.

The presentation describes the process of convection in a liquid and a gas on a particle scale. True or False statement test at the end with answers. This resource could be expanded upon as a lesson in school. It has been designed as a home learning activity. It is 1 in a series of 4 about thermal energy transfer.

Introducing static charge. It covers the principles of positive and negative charge. Conductors and insulators. Like and Unlike. Attract and Repel. Discharging. It would work in the classroom or as an online resource.

Describing the subatomic particles of the atom. Linking ideas of atomic number, nucleon number and isotopes.

Energy types identified. Activities are given energy values and total energy required calculations are set. All solutions are shown at the end.
