Understanding Terminal Velocity

What happens when a light basketball and a heavy workout ball are dropped at the same time?

• Neither ball hits the ground.

• The heavier ball hits the ground first.

• The lighter ball hits the ground first.

• Both balls hit the ground at the same time.

What is terminal velocity?

• The speed at which an object stops moving.

• The speed at which an object starts falling.

• The speed at which air resistance is negligible.

• The maximum speed an object reaches when falling.

Which factors influence an object's terminal velocity?

• Only the object's weight.

• Only the air temperature.

• Only the object's shape.

• Both the object's weight and the air resistance it encounters.

In the wind tunnel demonstration, why does the heavier ball require more wind speed to float?

• Because it is made of a different material.

• Because it is less aerodynamic.

• Because it has a larger surface area.

• Because it requires more force to balance gravity.

How does body position affect terminal velocity in the wind tunnel?

• Standing straight increases terminal velocity.

• Lying down decreases terminal velocity.

• Lying down increases terminal velocity.

• Body position has no effect on terminal velocity.
