Question

Gravitational force

Air resistance

Mass

Terminal velocity

Constant speed that a freefalling object reaches when the force due to gravity equals the force of air resistance

:: Measure of the amount of matter in an object

A lorce that acts on objects when moving through air

The attractive force between any two objects due to their mass

Answer 1

Here are the matched terms to their definitions:

1. Gravitational force: The attractive force between any two objects due to their mass.

2. Air resistance: A force that acts on objects when moving through air.

3. Mass: Measure of the amount of matter in an object.

4. Terminal velocity: Constant speed that a free-falling object reaches when the force due to gravity equals the force of air resistance.

Answer 2

The gravitational force on Earth is 9.82 m/s, while the gravitational force on the moon is 1.62 m/s.

Bruce uses this information to make the statement that a person's weight is the same on Earth as it is on the Moon. Is this statement true or false?

(1 point)

O True

O False

Answer 3

The statement is False.

A person's weight depends on the gravitational force acting on them, which varies between Earth and the Moon. Since the gravitational force on Earth (approximately 9.82 m/s²) is much greater than that on the Moon (approximately 1.62 m/s²), a person's weight on the Moon would be significantly less than their weight on Earth.

Answer 4

The gravitational force on Earth is 9.82 m/s, while the gravitational force on the moon is 1.62 m/s.

Karen uses this information to make the statement that a person's mass remains the same regardless of the object's location. Is this statement true or false?

(1 point)

True

False

Answer 5

The statement is True.

A person's mass remains the same regardless of their location, whether on Earth, the Moon, or elsewhere. Mass is a measure of the amount of matter in an object and does not change with variations in gravitational force. Weight, on the other hand, does change with location due to differing gravitational forces.

Answer 6

Categorize the following statements as either related to "Gravity" or related to "Air Resistance". (4 points)

Gravity

Air Resistance

Causes objects to fall towards Earth

Increases with the surface area of a falling object

Attracts objects toward one another due to their masses

Acts in the opposite direction of motion in the air

Answer 7

Here are the categorizations for the statements:

Gravity:

1. Causes objects to fall towards Earth
2. Attracts objects toward one another due to their masses

Air Resistance:

1. Increases with the surface area of a falling object
2. Acts in the opposite direction of motion in the air
