Subsequently, this module will allow you to measure parameters, velocity and acceleration, useful in illustrating both of these concepts. The presentation material and the code can be downloaded at ...

I got involved in discussion of g-forces this week in a completely different context, but having spent some time trying to sort it all out, I thought I'd devote this week's Football Physics post ...

However, remember the definition of acceleration and average velocity: ... This is a cool physics problem. I have only touched on the questions to answer. Expect more Hyperloop posts in the future.

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. It's impossible to talk about football these days without talking ...

Key concepts Physics Velocity Acceleration Gravity Introduction Have you ever dropped something and wondered how fast it was moving while falling? (If it was something fragile, you might not have ...

The iPhone makes it easy to do all kinds of cool physics. Like, say, use the change in velocity in an elevator to measure the height of a building.

Key Concepts Physics Motion Position Velocity Acceleration Measurement. ... If it accelerates, and two seconds later it has a velocity of 10 m/s, its acceleration was 5 m/s 2.

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

In order to change a velocity we have to apply an acceleration, which in turn implies that a force has to be applied over a period of time. But, since 'rigid' implies 'non-deformable' we have no time.
