# What are some common mistakes students make with Newton's second law?

Jun 8, 2018

Newton's second law of motion tells that with a given force, how much a body would accelerate.

#### Explanation:

According to the above fact,

It can be stated by:-

$a = \frac{\sum f}{m}$
where, a= acceleration f=force and m=mass of the body.

Most common mistake which people make ( even I had done this) is mentioning in a vertical force into an horizontal equation.

We should be careful in plugging in vertical forces into vertical equation and horizontal forces in horizontal equation.

This is because horizontal force= affects horizontal acceleration and vice versa.
