According to NASA, this law states, "Force is equal to the change in momentum per change in time.For a constant mass, force equals mass times acceleration." This is written in mathematical form as ...

On Earth, the downward force of gravity on a 1 kg mass is 10 N. This is called the strength of gravity (g). ... This is known as the acceleration of free-fall, the symbol for which is ‘g ...

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 ...
