Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in ...

This video guides you through the process of calculating the acceleration of a block sliding down an inclined plane with ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

When an object does not start at rest, you need to measure both the initial velocity and the final velocity to be able to calculate the acceleration. One way to to do this is to use a double mask. A ...
