1. Objects in 'real life' do not travel in straight line at constant speeds because of: Friction

2. When objects fall from heights, acceleration at which they travel is: Independent of mass and different everywhere in the universe

3. The acceleration of an object is dependent on: None of the above

4. An object in motion will stay in motion at constant speed in a straight line unless acted upon by an external unbalanced force is referred to as: Inertia

5. By Newton's 3rd law, we are told that every action has an equal and opposite reaction. Why is it then that when a person fires a bullet with a gun, the forces don't cancel out? : Because the forces applied are on the opposite objects

7. All objects experience inertia when moving, anywhere in the universe: True

8. Newton said that all objects that had mass had: Both inertia and gravitation

9. All natural magnets have: A north and south pole
