friction is a force that acts 

• in the same direction as the motion
• opposite to the direction of the motion
• opposite to the applied forces
• the same direction as the applied force

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

One object has twice as much mass as another object. The first object also has also twice as much...

• velocity
• gracitational acceleration
• inertia
• all of these
