What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

Which type of force(s) will cause a change in an object's motion?

• Newtonian forces
• zero net force
• balanced forces
• unbalanced forces

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
