FLASHCARD QUESTION

Front

What does Newton's 1st Law state?

Back

Newton's 1st Law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

FLASHCARD QUESTION

Front

What is Newton's 2nd Law?

Back

Newton's 2nd Law states that acceleration depends on two variables: the mass of the object and the amount of force applied. It can be summarized by the formula F=ma (Force = mass x acceleration).

What is Newton's 3rd Law?

Back

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.
