Who cares about the difference between mass & weight? inertia & gravity Newton’s 1st Law Qualitative law Newton’s 2nd Law Quantitative law f=ma

Force = mass X acceleration Who cares about the difference between mass & weight? Newton’s 2nd Law Quantitative law Force = mass X acceleration falling rate Same for all objects f = m * a 2 2

Force = mass X acceleration Who cares about the difference between mass & weight? Newton’s 2nd Law Quantitative law Force = mass X acceleration falling rate Same for all objects f = m * a 2 f = m * a 2 55 15 10 8 f = m a 4 4 55 10 15 8
