What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

True or False: Any object with mass has gravity.

Back

True

Front

Which model has greater gravitational attraction: Model A or Model B?

Back

Model A has greater gravitational attraction.

Front

What force keeps planets in orbit around the sun?

Back

Gravity.

Front

The planet Mars has less gravity than Earth because it has ___________ mass than Earth.

Back

less.

Front

What is a nebula?

Back

A nebula is a cloud of ice and dust in space.

Front

What is the relationship between mass and gravity?

Back

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

Front

What happens to gravity as distance increases?

Back

Gravity decreases as the distance between two objects increases.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What is inertia?

Back

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