Amplify Velocity, Mass, and Impact Forces Quiz

What happens to the force experienced during a collision if the objects are moving faster?

• It remains the same

• It decreases

• It increases

• It becomes zero

How does air resistance affect a falling object?

• It increases its velocity

• It changes its shape

• It decreases its velocity

• It increases its mass

Why does a crumpled piece of paper fall faster than a flat piece?

• It is smaller in size

• It is pushed harder by gravity

• It experiences less air resistance

• It is heavier

What is NOT a factor in changing the velocity of a falling object?

• Its shape

• Its mass

• The color of the object

• The air resistance it experiences

Objects with more mass collide with

• less force

• more force

• more velocity

• more air resistance

Changing an object's mass does not change the speed at which it falls.

• True

• False

Open parachutes have large surfaces that...

• interact with air molecules

• helps increase the velocity of falling objects

• helps decrease the velocity of falling objects

• makes the impact force smaller

Which statement is true?

• A flat piece of paper and a crumpled piece of paper have the same mass and the same velocity when falling.

• A flat piece of paper will fall faster than a crumpled piece of paper.

• A flat piece of paper will fall slower than a crumpled piece of paper since it has more surface exposed to the air.

• A flat piece of paper and a crumpled piece of paper have the same mass.
