Which of the following are Aristotle's views of vertical motion?

• Any object not in its natural place will strive to get there

• Objects fall at the same rate

• Heavier objects fall much faster than lighter objects

Which of the following are Galilei's views of vertical motion?

• Any object not in its natural place will strive to get there

• Objects fall at the same rate

• Heavier objects fall much faster than lighter objects

• Any two objects that are dropped together will fall together regardless of their weight if air resistance is negligible

Which of the following is Aristotle's view of horizontal motion?

• Any object not in its natural place will strive to get there

• Force is needed to start and sustain the motion of an object

• Force is not needed to sustain the motion of an object

• Force is required to change motion

Which of the following are Galilei's views of horizontal motion?

• Force is not needed to sustain the motion of an object

• Force is required to change motion (accelerate)

• Force is needed to start and sustain the motion of an object

• Any two objects that are dropped together will fall together regardless of their weight if air resistance is negligible

Which of the following is Aristotle's view of projectile motion?

• A projectile is influenced by vertical motion due to the force of gravity and horizontal motion that is uniform

• A force is needed to start an object to move through the air until its natural motion eventually brings it to earth
