The force of gravity between two objects is directly proportional to which of the following?
The gravitational force would be twice as big
The masses of each object.
It will decrease her terminal velocity.
The leaf is falling with a constant velocity.
No, because it continued to accelerate until it hit the ground.
The object is not accelerating.
The gravitational force between the sun and Earth.
Law of Equal Areas

Law of Equal Areas
How does a parachute change the terminal velocity of a skydiver?
The gravitational force would be twice as big
The masses of each object.
It will decrease her terminal velocity.
The leaf is falling with a constant velocity.
No, because it continued to accelerate until it hit the ground.
The object is not accelerating.

Law of Equal Areas
A leaf falls from a tree. As you are watching the leaf fall, how can you tell that is has reached its terminal velocity?
The gravitational force would be twice as big
The masses of each object.
It will decrease her terminal velocity.
The leaf is falling with a constant velocity.
No, because it continued to accelerate until it hit the ground.
The object is not accelerating.

Law of Equal Areas
Which of the following statements about an object traveling at terminal velocity is true?
The gravitational force would be twice as big
The masses of each object.
It will decrease her terminal velocity.
The leaf is falling with a constant velocity.
No, because it continued to accelerate until it hit the ground.
The object is not accelerating.
The gravitational force between the sun and Earth.
Law of Equal Areas
The sun has more mass than Earth, which has more mass than the moon. If the distance between each object was the same, which gravitational force would be the largest?
The gravitational force would be twice as big
The masses of each object.
It will decrease her terminal velocity.
The leaf is falling with a constant velocity.
No, because it continued to accelerate until it hit the ground.
The object is not accelerating.
The gravitational force between the sun and Earth.
Law of Equal Areas
Suppose the sun was replaced by a star that had twice as much mass. How would the gravitational force between the sun and its planets change?
The gravitational force would be twice as big
The masses of each object.
It will decrease her terminal velocity.
The leaf is falling with a constant velocity.
No, because it continued to accelerate until it hit the ground.
The object is not accelerating.
The gravitational force between the sun and Earth.
Law of Equal Areas

The gravitational force would be twice as big
The masses of each object.
It will decrease her terminal velocity.
The leaf is falling with a constant velocity.
No, because it continued to accelerate until it hit the ground.
The object is not accelerating.
