When an apple falls to the ground, what is happening?
Gravity pushes the apple up, away from the Earth.
Gravity pulls the apple down, towards the Earth.
Magnetism pushes the apple up, away from the Earth.
Magnetism pulls the apple down, towards the Earth.
Which of the following statements about gravity and magnetism is NOT true?
Gravity and magnetism are both invisible forces.
Gravity and magnetism can both pull on objects.
Gravity pulls on everything, but magnetism only pulls on magnetic objects.
Gravity pulls only on magnetic objects, but magnetism pulls on everything.
Why can you jump higher on the Moon than on Earth?
You can jump higher on the Moon because it has more gravity than Earth.
Since the Moon has less mass than the Earth it will have less gravity. Therefore, it doesn't pull as much as the Earth. That is why you jump higher.
Since the Moon has more mas than the Earth, the Moon will pull more and therefore you will jump higher than on Earth.
You will jump higher on the Moon because it has less gravity than the Earth.
Which of the following has the strongest gravitational pull?
The Earth
The Sun
Mars
Jupiter
The Moon

What effect does the Earth's gravity have on us?
It lets us float.
It pulls us to the Earth.
We are too small for it to effect us.
It moves us around in circles.
This force attracts all objects toward each other.
electricity
gravity
weight
magnetism
A person would weigh more on Jupiter than on Earth because_____________________.
Jupiter has less mass, and therefore less gravity.
Jupiter has more mass, and therefore less gravity.
Jupiter has less mass, and therefore more gravity.
Jupiter has more mass, and therefore more gravity.
