From the Institute of Physics, these activities allow students to understand the idea of electric charge and its relationship to a flow of current. There are a range of activities and these include: • using an analogy to represent the movement of charge • defining current and the coulomb • calculations to show the...

From the Institute of Physics, in this learning episode, students calculate electrical power and through discussion, review their understanding of: • current • potential difference • electromotive force (emf) • charge • drift velocity Students are reminded of the idea that power is the rate of doing work (or the...

In these activities, from the Institute of Physics, the concept of electrical power is explored. Students find that the energy transferred by an electrical component depends on the potential difference, current and the time for which it operates.

...

From the Institute of Physics, this learning episode links Kirchhoff’s circuit laws to the conservation of charge and energy. Students can verify the laws experimentally and use them to solve simple circuit problems.

...

Produced by the Institute of Physics, this learning episode can be used to revises the idea of electromotive force (emf), introduce internal resistance and the consequent energy losses.

The activities include:
•...

Produced by the Institute of Physics, this learning episode helps students to distinguish alternating from direct currents before revising why alternating current (ac) is so important.

The range of activities include...

In this learning episode from the Institute of Physics, students are introduced to capacitors. Through practical investigations, students look at their charge and discharge process.

The activities include:
•...

Produced by the Institute of Physics, this learning episode looks at the energy stored in a capacitor. Students undertake a practical investigation to look at the energy stored and how this varies with potential difference and capacitance.

...

Produced by the Institute of Physics, this learning episode contains demonstrations and practical activities through which students learn about the conditions for static equilibrium (excluding moments of forces).

Students look at:
• forces on a horizontal washing line with a weight in the middle...

In this learning episode, from the Institute of Physics, students look at the forces involved when one vehicle impacts another object. This can be used to illustrate the forces, acceleration and deceleration involved. It considers the effect of the distance over which a force acts rather than the time of action of...

This learning episode, from the Institute of Physics, uses demonstrations and worked examples to examine the forces involved in changing momentum. It introduces the concept of impulse.

The activities in the learning episode include:
* showing that impulse equals change in momentum
* a...

This learning episode from the Institute of Physics, uses worked examples and discussion to help students gain an understanding of circular motion, including linear velocity, angular velocity and angular acceleration. The activities include: * discussing linear and angular velocity * calculating angular velocity *...

Produced by the Institute of Physics, this learning episode assists students to use a mathematical approach to simple harmonic motion, starting from its physical basis and the forces involved. In the activities, students look at: * restoring forces in simple harmonic motion (SHM) * graphical representations of SHM...

In this learning episode, from the Institute of Physics, students interpret graphs of waves to understand concepts such as wavelength, frequency and phase.

The activities in this episode include:
• plotting displacement and drawing longitudinal waves
• considering phase
• understanding...

In this learning episode, from the Institute of Physics, students look at standing waves in musical instruments and measure their wavelength. Microwaves are used to estimate the speed of light.

The activities include:
* demonstrating waves in a rope
* how superposition results in standing waves...
