Gravity and Earth

Front

What is gravitational force?

Back

Attraction between two masses.

Front

What is the slingshot effect?

Back

The use of the Moon's gravity to propel a spacecraft from the Moon's orbit back toward Earth.

Front

True or False: The closer an object is to another, the stronger the gravitational force.

Back

True.

Front

What happens when two objects of the same size and mass are dropped from different heights?

Back

The ball that is closer to the ground will hit the ground first.

Front

If mass increases, what happens to the force of gravity?

Back

The force of gravity increases.

Front

If distance increases, what happens to the force of gravity?

Back

The force of gravity decreases.

Front

What is the relationship between mass and gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

What is the effect of distance on gravitational force?

Back

Greater distance results in a weaker gravitational force.

Front

What is the formula for 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 of the two masses.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.
