Liam is studying Newton's 2nd Law and he is curious about the relationship between mass and acceleration. Can you help him understand this?

• Acceleration is directly proportional to mass according to Newton's 2nd Law.

• Mass and acceleration are unrelated according to Newton's 2nd Law.

• Acceleration is proportional to the square of mass according to Newton's 2nd Law.

• Acceleration is inversely proportional to mass according to Newton's 2nd Law.
