Demonstration: A mass suspended on a spring will oscillate after being displaced. The period of oscillation is affected by the...

Practical Activity 14-16

Every mechanical wave has its origin in an oscillating object. The particles in the medium themselves oscillate, in a similar...

Teaching Guidance 14-16

Alice, Bob and Charlie are once again at the railway station (no rest for good behaviour). Charlie is on the platform and...

Physics Narrative 14-16

Acceleration, velocity and position have been introduced as descriptions of motion true at an instant. Questions such as When...

Physics Narrative 14-16

Physics is all about noticing, and then reusing, common patterns. You got a handle on velocity–time graphs by thinking about...

Physics Narrative 14-16

A rather concise way of expressing the connection between velocity and accelerations is to say that the rate of change of...

Physics Narrative 14-16

In this episode you've concentrated on the relationships between the measures of motion, exploring the connections between...

Physics Narrative 14-16

Some physical quantities are essentially directional. Force is one such. As soon as you describe a force, it's possible to ask...

Physics Narrative 14-16

Displacement is a vector quantity; it describes the difference in position between two points, measured from one to the other.
