_________ opposes the motion of one object moving past another. 

• friction 
• velocity

An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

• slowing motion in a straight line
• accelerating motion in a straight line
• constant motion in a straight line
• constant motion in an unpredictable direction

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 

What is Newton's First Law all about?

• Balanced forces

• Unbalanced forces

• Changing forces

• Resultant forces
