What is the role of air resistance in a parachute?

• Air resistance makes the parachute heavier.

• Air resistance increases the speed of descent.

• Air resistance slows down the descent of a parachute, allowing for a safer landing.

• Air resistance has no effect on parachute landing.

How does air resistance affect a falling feather?

• Air resistance causes the feather to float upwards.

• Air resistance has no effect on the feather's fall.

• Air resistance makes the feather fall faster than a rock.

• Air resistance significantly slows the falling feather, causing it to descend slowly.

How does friction help in writing with a pencil?

• Friction prevents the pencil from touching the paper.

• Friction makes the pencil harder to write with.

• Friction causes the pencil to break easily.

• Friction allows the pencil to transfer graphite onto the paper, enabling writing.
