Gravity and Inertia Flashcard (S6E1.d)

Front

What is the primary reason planets in our solar system orbit the sun?

Back

Because the sun has the most mass.

Front

What does inertia tell us about the motion of an object?

Back

Inertia tells us that we need a force to get an object moving or to make it stop.

Front

How does distance affect the force of gravity between two objects?

Back

The smaller the distance between two objects, the larger the force of gravity between them.

Front

What is the force that holds the solar system together?

Back

Gravity.

Front

Who was the first scientist to study and experiment with gravity?

Back

Isaac Newton.

Front

Define gravity in simple terms.

Back

Gravity is the force that attracts two bodies toward each other.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the relationship between mass and inertia?

Back

Inertia is directly related to mass; more massive objects have greater inertia.

Front

What happens to the gravitational force if the distance between two objects is doubled?

Back

The gravitational force decreases.
