2.2: Terminal velocity

What happens to drag forces as objects move faster in air or water?

• Drag forces decrease

• Drag forces increase

• Drag forces remain constant

• Drag forces become zero

What happens to the resultant force when drag forces increase?

• Resultant force increases

• Resultant force decreases

• Resultant force remains constant

• Resultant force becomes zero

When do forces become balanced?

• When drag forces become zero

• When drag forces are equal to weight

• When drag forces are equal to thrust

• When drag forces are equal to weight or thrust

What happens to the object when forces become balanced?

• The object stops accelerating and continues to move at constant speed

• The object stops moving

• The object starts accelerating

• The object changes direction

What is the constant speed called when forces become balanced?

• Terminal speed

• Terminal velocity

• Constant speed

• Balanced speed
