How are "Mass" and "Weight" different?

• Mass = amount of matter; Weight = gravity's effect

• Mass = velocity ; Weight = force

• Mass = gravity's effect; Weight = amount of matter

• There is no difference.

Which of Newton's Laws shows the relationship between force, mass and acceleration? (F = m*a)

• 1st law

• 2nd law

• 3rd law

• Law of Inertia
