# Newton's 2nd Law Practice Sheet

Newton's 2nd Law: When a force acts on an object the object's acceleration is in the direction of the force. Acceleration increases as the force gets larger. The acceleration produced by a net force is smaller for more massive objects.

Directions: Use the equation F=ma to solve for the following word problems.

For problems with calculations use UDRSS:

◻Data       ◻ Relationship       ◻ Substitution       ◻Solution
