Laws of Motion Vocabulary

What is Newton's First Law?

• The motion of an object doesn't change if the force on an object is zero.

• The motion of an object does change if the force on an object is zero.

• The speed of an object changes if the force on an object is zero.

• The speed of an object does not change if the force on an object is zero.

What is Newton's Second Law?

• A = M/F

• M = A/F

• A = F/M

• M = F/A
