What is mass?
Back
Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

FLASHCARD QUESTION
Front
What is the relationship between mass and acceleration according to Newton's Second Law?
Back
According to Newton's Second Law, as mass increases, acceleration decreases for a given force. This means that heavier objects require more force to accelerate at the same rate as lighter objects.
