Displacement close displacementA distance measured in a specified direction. is the distance moved in a straight line, in a given direction, from the starting point. Displacement = 24 m east. Velocity ...

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, ...

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 ...

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...
