What are the two classes of motion according to Aristotle?

• Natural motion and violent motion

• .Natural motion and sliding motion

• Natural motion and dynamic motion

• Natural motion and weak motion

What is the concept of Galileo of a projectile?

• A projectile is a moving object that will continue to move if it is impeded, and external force is needed to move it continuously

• A projectile is an object in motion, if unimpeded, will cease to move.

• A projectile is composed of uniform motion in the horizontal direction and uniformly accelerated motion in the vertical direction.

• A projectile is composed of uniform motion in the vertical direction and uniformly accelerated motion in the horizontal direction.

Aristotle proposed that all falling objects _____

• fall at the same speed

• .fall at the same acceleration

• .fall at the same distance

• fall at the same time

.If you are Galileo answer the ff question: "Why does a bowling ball and feather hit the ground at different times when dropped from the same height?

• .They don't; they hit the ground at the same time.

• One is more dense than the other

• One is heavier than the other.

• Air resistance

Earth's surface gravity is approximately 9.8 m/s.

Object in vacuum will not fall at the same time.

In physics, motion is when an object changes its position with respect to a reference point in a given time.

Galileo Galilei is the Father of History.

Force is not necessarily required for violent motion.
