Understanding Parachutes and Terminal Velocity

What is the primary purpose of a parachute?

• To increase the speed of a falling object

• To make an object fly

• To provide entertainment

• To slow down a falling object

Which two forces act on a falling object?

• Gravity and air resistance

• Air resistance and friction

• Friction and magnetism

• Gravity and magnetism

What happens to the speed of a falling object as air resistance increases?

• It fluctuates

• It increases

• It remains constant

• It decreases

What is terminal velocity?

• The speed at which an object stops falling

• The maximum constant speed of a falling object

• The speed at which gravity no longer acts

• The speed at which air resistance is zero

In the example of a rock falling, what balances the gravitational pull?

• Friction

• Wind

• Magnetic force

• Air resistance

What happens to a skydiver when they reach terminal velocity?

• They ascend

• They accelerate

• They fall at a constant speed

• They stop falling

Why does a skydiver open their parachute?

• To stop falling immediately

• To increase air resistance and slow down

• To decrease air resistance

• To increase their speed

What effect does opening a parachute have on terminal velocity?

• It has no effect

• It decreases terminal velocity

• It stops terminal velocity

• It increases terminal velocity

What is the role of air resistance in skydiving?

• To have no effect

• To balance gravity and slow descent

• To increase the speed of descent

• To make the skydiver ascend

How does a parachute ensure a safe landing?

• By increasing the speed of descent

• By stopping the descent completely

• By increasing air resistance and reducing speed

• By decreasing air resistance
