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 ...

In science, there are thousands of ways to measure the world around us that the average person may never encounter. For example: Pascals to measure pressure, Candles to measure light intensity, and ...

Understanding this relationship between mass and force is crucial for grasping the fundamental concepts of motion in physics. By appreciating their roles, you can delve deeper into how objects move ...

Speaker one We’ve been using Sir Isaac Newton’s theories for hundreds of years and still use his equations today. Now, how can we test Newton’s second law using equipment found in our laboratory?

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, ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. This helps, sort of, but as more numbers get thrown around, it can get ...
