Questions and Answers
According to Aristotelian physics, what is the primary reason an arrow shot from a bow eventually falls to the ground?
According to Aristotelian physics, what is the primary reason an arrow shot from a bow eventually falls to the ground?
- The 'violent motion' imparted to the arrow is overcome by its natural tendency to return to Earth. (correct)
- The arrow loses its initial inertia and succumbs to its natural state of rest.
- Air resistance gradually dissipates, causing the horizontal component of velocity to decrease.
- The continuous force applied by the bow dissipates over time, causing the arrow to slow down.
Which of the following statements best describes Galileo's contribution to the understanding of projectile motion?
Which of the following statements best describes Galileo's contribution to the understanding of projectile motion?
- He analyzed projectile motion into independent horizontal and vertical components. (correct)
- He showed that projectiles move in perfect circles due to the influence of aether.
- He proved that heavier projectiles travel farther than lighter ones due to their greater inertia.
- He demonstrated that projectile motion is a result of a single force acting at an angle.
How did Galileo challenge Aristotle's view on falling objects?
How did Galileo challenge Aristotle's view on falling objects?
- By demonstrating that heavier objects fall faster due to the continuous force of gravity.
- By arguing that the rate of falling depends on the object's shape rather than its mass.
- By showing that the speed of a falling object is directly proportional to its weight and air resistance.
- By proving that all objects fall at the same rate in a vacuum, regardless of their mass. (correct)

Description
Explore Aristotelian and Galilean concepts of motion. Aristotle's views, based on observation, distinguished between natural and violent motion. Natural motion dictates objects moving toward their 'natural' place based on elemental composition, while violent motion requires an external force.
