Question

A coin (5 grams), a small parachute (21 grams), and a hammer (710 grams) are all dropped from a height of 10 meters. The coin and the hammer take about the same amount of time to fall. Which statement describes the time it takes for the parachute to fall?(1 point)
Responses

It takes longer to fall because it experiences greater air resistance.
It takes longer to fall because it experiences greater air resistance.

It takes less time to fall because it has the most surface area.
It takes less time to fall because it has the most surface area.

It takes the same amount of time to fall because the effect of gravity is the same.
It takes the same amount of time to fall because the effect of gravity is the same.

It takes less time to fall because it has the least mass

Answer 1

It takes longer to fall because it experiences greater air resistance.

Answer 4

How does an open parachute slow a skydiver’s fall?(1 point)
Responses

The parachute weakens the force of gravity.
The parachute weakens the force of gravity.

The parachute increases the force opposing gravity.
The parachute increases the force opposing gravity.

The parachute changes the mass of the skydiver.
The parachute changes the mass of the skydiver.

The parachute pulls the skydiver up.

Answer 5

The parachute increases the force opposing gravity.

Answer 6

A science class is planning an investigation about gravity and objects on Earth. In three to four sentences, explain the steps the class should take to provide data to help them make a conclusion about the effect of gravity on objects of different masses. 4 different objects of different mass in the same height at the same time

Answer 7

To investigate the effect of gravity on objects of different masses, the science class should first select four objects of varying masses. Then, they should place all four objects at the same height and release them simultaneously. They should use a timer to record the time it takes for each object to reach the ground. By collecting data on the time taken for objects of different masses to fall, the class can analyze how gravity affects objects of varying masses and draw conclusions based on their observations.
