The Pull of Earth's Gravity

Front

Why is the Moon's gravitational pull weaker than Earth's?

Back

The Moon has less mass than Earth, so its gravitational pull is weaker.

Front

How does the Moon's gravity compare to Earth's gravity?

Back

The Moon's gravity is about one sixth of Earth's gravity.

Front

What happens to a ball thrown on the Moon compared to Earth?

Back

On the Moon, you could throw a ball about six times higher than on Earth because the force of gravity is not as strong.

Front

How does the Moon's gravity affect Earth?

Back

The Moon's gravitational force causes Earth's tides, or the regular rise and fall of water along the shore.

Front

What causes the bulge of water on Earth?

Back

Earth's water bulges on the Moon-facing side and the side facing away from the Moon due to the Moon's gravitational force.

Front

What is the result of the water bulge caused by the Moon's gravity?

Back

The water level rises where the bulge is and lowers where it is not, causing changing tides as the Moon travels around the Earth.
