Q4 QUIZ 3: SLM 2

According to Galileo heavier objects fall faster than lighter ones.

• TRUE

• FALSE

In the absence of air resistance, a dry cotton ball would fall faster than a stone.

• TRUE

• FALSE

In a vacuum, a feather falls faster than a metal ball.

• TRUE

• FALSE

In Galileo’s experiment he found out that the steeper the inclined

plane , the lesser is the acceleration

• TRUE

• FALSE

One of Galileo’s observation was that the maximum

acceleration of the rolling ball was reached when the inclined

plane was positioned vertically as if the ball was simply falling.

• TRUE

• FALSE

According to Galileo the ball would decrease in speed when

rolling in a horizontal plane.

• TRUE

• FALSE

Law of inertia states that gravity is needed in order for a body to

move.

• TRUE

• FALSE

Galileo observed that a ball released down from an inclined

plane will reach exactly the same height as it simultaneously rolls

up in another inclined plane.

• TRUE

• FALSE

According to Galileo, a ball rolling in a horizontal plane would

keep moving considering that friction is neglected.

• TRUE

• FALSE

Galileo’s assertion and Newton’s inertia are similar, the only

difference is the concept of force.

• TRUE

• FALSE
