Gravity

Front

What is the law that states every object in the universe attracts every other object?

Back

Newton's Law of Universal Gravitation states that every object attracts every other object, with the force depending on their masses and the distance between them.

Front

How does mass affect gravitational attraction?

Back

The greater the mass of an object, the greater the gravitational attraction it exerts.

Front

How does distance affect gravitational attraction?

Back

The farther apart two objects are, the weaker the gravitational attraction between them.

Front

What happens to gravitational force as distance increases?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is freefall?

Back

An object is in freefall when the only force acting on it is gravity.

Front

What is the relationship between distance and gravitational force?

Back

The closer the distance, the greater the gravitational force; the greater the distance, the lesser the gravitational force.

Front

What is an example of a situation with strong gravitational attraction?

Back

Two large masses, like Earth and a falling apple, experience strong gravitational attraction.

Front

What is an example of a situation with weak gravitational attraction?

Back

Two small objects, like a marble and a paperclip, experience weak gravitational attraction.

Front

What is the formula for gravitational force?

Back

The gravitational force (F) can be calculated using the formula F = G * (m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2, a key value in calculating gravitational force.
