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, ...

Your everyday notion of forces probably includes pushing and pulling and similar actions. Technically, when something is pushed or pulled we say that "a force is applied to the object". What happens ...

So far we have only considered the influence of one unbalanced force on an object and we found that the effect was to accelerate it. If the same force is applied to the same mass we always measure the ...

Do you need some practice with force diagrams for your introductory (or advanced) physics course? Here are three questions (and the last one is awesome) about the motion of a bike as it is pulled.

You might have seen some of the viral videos of this giant steel slide at Belle Isle Park in Michigan, which temporarily closed this summer because riders were sliding so fast they were losing contact ...
