You were born on a planet where acceleration is omnipresent–both in the natural and in the made world. Release a stone held...

Physics Narrative 14-16

So you can notice an acceleration, and the lurches of acceleration we've introduced. Examples we've picked so far might...

Physics Narrative 14-16

Velocity is a tricky thing to measure. One of the reasons it is tricky is that humans have no inbuilt velocity sensor. We do...

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

We've introduced the idea that looking out in space is looking back in time on several occasions throughout the SPT materials...

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

Reporting any velocities unambiguously depends on making explicit the point of view that you've chosen. So all velocities are...

Physics Narrative 14-16

Velocity vectors predict where something will end up after a short interval of time. Following a sequence of such predictions...

Physics Narrative 14-16

A central idea here, repeated often, is that accumulations over time lead to changes. To understand the structure of these...
