Forces SC.6.P.13.1

Front

What happens to gravitational force as mass increases?

Back

Gravitational force increases.

Front

What happens to gravitational force as the distance between two objects increases?

Back

Gravitational force decreases.

Front

What does the width of arrows in a gravitational illustration represent?

Back

The strength of the gravitational attraction between two objects.

Front

Why are the arrows thicker in the top figure of a gravitational illustration?

Back

The distance between the objects is shorter in the top figure compared to the bottom figure.

Front

Why would a person weigh less on the Moon than on Earth?

Back

The Moon has less mass and therefore less gravity.

Front

What happens to your mass if Earth's mass is cut in half?

Back

Nothing; mass is not affected by gravitational force.

Front

What is the Law of Universal Gravitation?

Back

It states that every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

Define gravitational force.

Back

The attractive force between two objects due to their mass.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

How does gravity affect objects in free fall?

Back

Objects in free fall experience acceleration due to gravity, which is approximately 9.8 m/s² on Earth.
