Gravity

Front

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

Which has more mass, the Earth or the Moon?

Back

Earth has more mass than the Moon.

Front

What is the relationship between mass and gravitational attraction?

Back

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

Front

Which has a stronger force of gravity, the Earth or the Moon?

Back

The Earth has a stronger force of gravity than the Moon.

Front

When will the forces of gravity between two objects be the greatest?

Back

The forces of gravity will be greatest when the masses of both objects are large and the objects are close together.

Front

True or False: Any object with mass has gravity.

Back

True.

Front

What is the effect of distance on gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the 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 the gravitational constant (G)?

Back

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

Front

How does gravity affect objects in free fall?

Back

In free fall, all objects accelerate towards the Earth at the same rate due to gravity, regardless of their mass.
