I'm not going to tell you the value for an accelerating grasshopper. Instead, I am going to show you how you can figure it out. Well, of course you need a grasshopper first. Right? Thanks to the ...

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 a relationship between two variables is defined by a curve it means that the gradient, or rate of change is always varying. An average speed for a journey can be found from a distance-time graph ...

This force will cause the cart to accelerate—in this case, to the left, or the opposite way it was heading, which is why it slows down during impact and even reverses direction. But what is the ...
