ARISTOTLEAN AND GALILEAN VIEWS OF MOTION

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

Which would fall with greater acceleration in a vacuum—a leaf or a stone?

• the leaf
• the stone
• They would accelerate at the same rate.
• It is difficult to determine without more information.

What are the two classes of motion according to Aristotle?

• Natural motion and dynamic motion

• Natural motion and sliding motion

• Natural motion and violent motion

• Natural motion and weak motion

Which of the following is an example of natural motion according to Aristotle?

• A smoke rises

• A kicked soccer ball

• A pulled bag

• A pushed trolley.

Which of the following objects A, B, or C with masses 3 kg, 6 kg, and 9 kg respectively will reach the ground first neglecting air resistance?

• Object A will reach the ground first.

• Object B will reach the ground first.

• Object C will reach the ground first.

• The three objects will reach the ground at the same time.

4.A cannon ball when fired moves in a straight horizontal line because of a force called impetus made it move.

• Aristotle

• Galileo

Which form of motion always follows a curved path and requires an initial launch force that is greater than the force of gravity?

• Centripetal Motion

• Projectile Motion

• Free Fall Motion

• None of the Above

How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed
• less friction doesn't affect speed
