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 of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” ...

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 ...
