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

What is an example of a gravitational interaction?

Back

An example of a gravitational interaction is that the Earth orbits the sun.

Front

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

Back

True

Front

What holds all of the planets in orbit around the sun?

Back

Gravity holds all of the planets in orbit around the sun.

Front

When will the gravity between two objects be the least?

Back

The gravity between two objects will be the least when the masses of both objects are small and the objects are far apart.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with the mass of the objects involved.

Front

What is the relationship between distance and gravitational force?

Back

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

Front

What is the formula for calculating gravitational force?

Back

The formula for calculating gravitational force is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

What role does gravity play in the solar system?

Back

Gravity keeps the planets in orbit around the sun and governs the motion of celestial bodies.

Front

How does gravity affect the motion of objects on Earth?

Back

Gravity pulls objects towards the center of the Earth, causing them to fall when dropped.
