Q1. What is the difference between weight and mass?
Q2. Where is your weight greater, on Earth or on the Moon? How about your mass?
Q3. One kilogram (mass) weighs 9.8 N on Earth. Would it weigh more or less on the moon?
Q4. What is the net force on a box pushed to the right with 50 N (Newtons) of force, while being pushed to the left with 20 N of force?
Q5. What two quantities are necessary for a vector quantity?
Q6. If we push an object at constant velocity, how do we know how much friction acts on the object compared to our pushing force?
Q7. Suppose you push to the right on a piece of heavy furniture, but not hard enough to make it slide. Does a friction force act on the furniture?
Q8. List three types of friction and "generally" discuss which is strongest and weakest of the three.
Q9. Distinguish between speed and velocity.
Q10. Why do we say velocity is a vector and speed is not?
