Plot a graph of resultant force F in N on the y-axis against acceleration a in m/s 2 on the x-axis. Draw the line of best fit. The graph is a straight line through the origin. This tells us that ...

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 ...

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, ...
