Newton's 1st Law of Motion, also called the ​ ​ (a)   states that an (b)   at rest will remain at ​ (c)   and an object moving at a constant ​ (d)   will continue moving that way, unless acted upon by an ​ (e)   .

• Law of Inertia
• object
• rest
• velocity
• unbalanced force
• momentum

Newton's ​ (a)   states that ​ (b)   depends on an object's ​ (c)   and on the ​ (d)   acting on the object.

• 2nd Law of Motion
• acceleration
• mass
• net force
• 3rd Law of Motion
• weight
• force
