# Newton's 2nd Law Practice Sheet

**Newton's 2 ^{nd} 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:

◻ Units Force: Newtons Mass: kg Acceleration: m/s^{2}
