GR5 SCIENCE Understanding Gravity

What is the force that stops us from floating into space?

• Friction

• Gravity

• Magnetism

• Electricity

What is the relationship between the size of an object and its gravitational pull?

• The smaller the object, the stronger its gravitational pull.

• The larger the object, the stronger its gravitational pull.

• The size of an object has no effect on its gravitational pull.

• The size of an object only affects its gravitational pull on other objects of the same size.

Why don't we feel the gravitational pull of other objects around us?

• Because gravity is too weak to be felt.

• Because we are only affected by the gravity of very large objects.

• Because we are on the surface of the Earth, which has the strongest gravitational pull we can feel.

• Because gravity only affects objects in motion.

The Earth's gravity pulls everything on its surface toward its center.

• True

• False

If you drop a ball at the North Pole, it would look like it's falling down to someone standing at the South Pole.

• True

• False

What is gravity?

What happens when you throw something up in the air?

Why doesn't your bed float away?

Can you see gravity?

Does every object have a gravitational pull?
