FLASHCARD QUESTION

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = ma, where F is force, m is mass, and a is acceleration.

FLASHCARD QUESTION

Front

What does it mean for an object to have a net force acting on it?

Back

A net force acting on an object means that the total force acting on the object is not zero, resulting in a change in the object's motion.
