Question

What is a force?

Answer 1

A force is a push or a pull.

Explanation:

A force is a push or a pull and the strength of that push or pull is given the units N (Newtons). If there is more than one force acting on a mass, the acceleration is given by Newton's 2nd Law:

`F_"net" = m*a`

where `F_"net"` is the sum of the existing forces. The sum is formed using "vector algebra".

Notice that since Isaac Newton developed the above law, the unit given to the magnitude of a force is also named for him.
