Electron Diffraction Tube

In this video, produced by the National STEM Learning Centre and Network and the Institute of Physics, Alom Shaha explains the elements of an electron diffraction tube and how to use one to demonstrate a diffraction pattern. The video is aimed at teachers but it could also be used with older students to...

Episode 202: Forces in Equilibrium

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...

Episode 207: Projectile Motion

This learning episode, from the Institute of Physics, looks at the independence of vertical and horizontal motion. The crucial concept is that vertical acceleration does not affect horizontal velocity. This explains all projectile motion.

There are a range of activities which include:
• demonstrating...

Episode 209: Drag, Air Resistance, Terminal Velocity

Produced by the Institute of Physics, this learning episode considers the forces acting on a falling body in air and moves on to related experimental work.

The activities include:
• demonstrating the motion of falling bodies
• understanding upthrust
• investigating air resistance using falling...

Episode 215: Forces on Vehicles

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...

Episode 216: Energy Changes

This learning episode, from the Institute of Physics, looks at kinetic energy, work and velocity in relation to the braking distance of a vehicle.

Two experiments are included, both of which connect work done in braking to the initial kinetic energy of the decelerating vehicle.

The activities...

Episode 217: Conservation of Energy

From the Institute of Physics, although concerned with conservation of mechanical energy, this episode extends the principle to its wider context in order to give the students a full appreciation of the overarching nature of the principle when they meet it in different situations.

The activities include:...

Episode 222: Impulse of a Force

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...

Episode 224: Describing Circular Motion

From the Institute of Physics, this learning episode introduce students to the importance of circular motion and the need for a centripetal force to keep an object moving along a circular path.

The activities include:
* observing circular motion
* whirling bucket and centripetal force

Episode 227: Hooke’s Law

In this learning episode from the Institute of Physics, students use Hooke's law to demonstrate the strength and stiffness of materials when subject to linear tensile or compressive forces.

The activities include:
• recap of Hooke's law
• explaining tension and extension in a variety of...
