Newtons second law of motion does not state anything it is a formula or equation. The second law was discovered in 1687. The equation is F=MA yes the great equation. “F” is force, “M” is mass and “A” is acceleration. So when you substitute the letters with the words it becomes, force is equal to mass times acceleration.
This was a breakthrough in physics back then and revolutionised the way we looks at the world. Both the first law and the second law were discovered in the same year (if you have not read my previous blog on the first law of motion then you can go and read it).

The units of measuring the formula
Force is measured in newtons, mass is kilograms and acceleration is measured in meters per second . When you came to the of solving a question if you try solving one you will end up with newton meters per second squared which is a joule. I will be talking about the Newtons third law of motion in my next blog.
