Motion and Stability

 A boy designed and created the parachute shown here. When he tested it, the found that it fell too slowly.  What could he do to make his parachute fall more quickly? 

• use a heavier load 

• make the canopy smaller

• make the canopy out of a thinner material

• all the above

 On a planet the same size as Earth, where the atmosphere is thinner than it is on Earth, objects will:

• fall slower

• float

• fall faster

• fall at the same speed

When an object is held and released at 10 feet in the air, what evidence supports the claim that objects fall towards the center of the Earth?

• The object stays where it is.

• The object falls toward the ground.

• The object falls toward the sky.

Since an object that is initially stationary when held moves downward when it is released, there must be a force acting on the object that pulls the object toward the center of the Earth. What is the force acting on the object?

• Magic

• anti-gravity

• gravity

• inertia

What evidence supports the claim that the model of the water atmosphere is thicker?

• The golf ball falls faster in the water atmosphere than the air atmosphere.

• The golf ball falls slower in the water atmosphere than the air atmosphere.

• The golf ball falls slower in the air atmosphere than the water atmosphere

 Look at the chart of data:

According to the data, which canopy size would allow cargo to arrive the safest from a fall?

• Small Canopy

• Large Canopy

• Medium Canopy

What evidence suggests the parachute canopy material and size is the best for protecting the cargo according to the data?

• The small canopy would be best for protecting cargo because it will fall in 1.3 seconds which is faster.

• The Large canopy would protect the cargo because it falls in 4.5 seconds which is slower than the other sizes.
