Gravity

Front

What happens to the pull of gravity as the distance between two objects increases?

Back

The pull of gravity decreases.

Front

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

Back

When the masses of both objects are large and the objects are close together.

Front

What physical quantity changes with different gravitational forces?

Back

Weight.

Front

What happens to the strength of gravity as two objects are farther apart?

Back

The gravity becomes weaker.

Front

Which quantity remains constant regardless of the gravitational field?

Back

Mass.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with the mass of the objects.

Front

What is the formula for gravitational force between two masses?

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

How does gravity affect weight on different planets?

Back

Weight varies depending on the gravitational force of the planet, while mass remains constant.

Front

What is the gravitational constant (G)?

Back

G is approximately 6.674 × 10^-11 N(m/kg)^2, a constant used in the calculation of gravitational force.

Front

What is the effect of gravity on objects in free fall?

Back

Objects in free fall accelerate towards the Earth at a rate of approximately 9.81 m/s², regardless of their mass.
