What is the purpose and function of a parachute?

• To slow down the descent of an object
• To propel an object forward
• To heat up the atmosphere
• To generate electricity
• To increase the speed of an object

How does air resistance affect the motion of an object in the atmosphere?

• It opposes the motion and slows down the object
• It accelerates the object
• It has no effect on the object
• It changes the direction of the object
• It increases the mass of the object

Why is it important to reflect on the design and testing process of a parachute?

• To evaluate strengths and weaknesses
• To ignore any improvements
• To rush into the next iteration
• To avoid modifications
• To limit creativity

What are the three main components of a parachute?

• Canopy, suspension lines, harness
• Wings, propellers, landing gear
• Rotor, fuselage, tail
• Tires, brakes, engine
• Cabin, seats, windows

Which shape is considered the most effective for a parachute?

• Dome or cone shape
• Cube or rectangular shape
• Sphere or ball shape
• Cylinder or tube shape
• Pyramid or triangular shape

What is the role of suspension lines in a parachute?

• To connect the canopy to the harness
• To provide cushioning upon impact
• To generate lift
• To control the direction of flight
• To store air for inflation

Which material is ideal for making a parachute?

• Lightweight and strong material
• Heavy and rigid material
• Transparent and brittle material
• Flexible and elastic material
• Absorbent and porous material

What type of force opposes the motion of an object through the air?

• Air resistance
• Gravitational force
• Magnetic force
• Frictional force
• Centripetal force

Which law of motion states that for every action, there is an equal and opposite reaction?

• Newton's third law of motion
• Newton's first law of motion
• Newton's second law of motion
• Newton's law of universal gravitation
• Einstein's theory of relativity

What type of data should be measured and recorded during parachute tests?

• Descent time, descent rate, impact force
• Temperature, color, weight
• Speed, distance, volume
• Pressure, density, viscosity
• Voltage, current, resistance
