Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

True or False: Any object with mass has gravity.

Back

True

Front

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

Back

Because the Moon has less mass and therefore less gravity.

Front

True or False: Gravity attracts all objects towards one another.

Back

True

Front

What happens to the mass of an object as it moves away from the center of the Earth?

Back

The mass stays the same.

Front

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

Back

Model A.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with greater mass.

Front

What is the formula for calculating 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.

Front

What is the gravitational constant (G)?

Back

G is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.
