You will have 20 multiple choice questions to answer over the material, one point each for a total of 20 points. The 'clock' is set for 20 minutes, so make sure you have reviewed the material and are ready to take this. You'll be able to take this quiz twice and the highest score of the two attempts will be kept. Good luck! Take the Quiz Again 1 / 1 pts Question 1 According to Aristotle, how fast do heavy objects fall compared to light objects? Aristotle stated that light objects fall faster than heavy objects. Aristotle did not formulate a statement about the speed of falling objects

Aristotle stated that heavy objects fall faster than light objects. 1 / 1 pts Question 2 According to Galileo, how much force (directed along the surface, besides the upward force from the flat surface) is needed to keep a ball rolling on a flat surface (neglecting the effect of friction)? No force is needed to keep the moving ball moving in the absence of friction. The force that started the ball moving must remain on the ball to keep it in motion A constant force equal to the ball's mass. A force whose magnitude is equal to the weight of the ball 0 / 1 pts Question 3 Incorrect Incorrect When a falling object has reached its terminal velocity, its acceleration is constant zero

The forces acting on the book that keep it motionless are _______. gravity and the equilibrium force gravity and the support force friction and gravity gravity and the net force 1 / 1 pts Question 13 A car is traveling with constant velocity. This means that _______. it is traveling in a straight line and its speed is not changing it is traveling along a curve and its speed is not changing
