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, ...
The relationship between acceleration, velocity change and the time taken for the change is given by this formula. \(\text{acceleration}=\frac{\text{change in velocity}}{\text{time taken}}=\frac{\text ...
