Gravity Quiz Review

Why does the Earth orbit the Sun rather than any other planet in the solar system?

• The mutual repulsions among all planets.
• The Earth is closer to the sun than other planets.
• The sun has the most mass.
• The rotational movement of all the planets cause them to rotate around the sun.

Between which pair of objects would the LARGEST gravitational attraction be found? Assume there is an equal distance between each pair of objects. 

• Human and the Earth
• Ant and the Earth
• Small bird and the Human
• Small bird and the Earth

In which situation would the object weight the LEAST (assume all objects have the same mass)?

• an object on Earth
• on object on the moon
• an object halfway between the Earth and moon
• an object closer to the moon than to the Earth

What two variables affect the gravitational force between objects?

• weight and mass
• volume and weight
• distance and mass
• rotation and distance

Considering the factors that affect gravitational pull, in which location would the gravitational pull from the Earth the LEAST on you?

• when you visit friends at the beach
• when meeting friends on the second floor of the mall
• when climbing to the top of the world's highest mountain
• when deep sea diving to search for sunken treasure

The moon and the sun both affect the tides on Earth. Which evidence BEST supports this hypothesis?

• The sun's and moon's gravitational attraction to the water is unique.
• Every object exerts gravitational force on every other object.
• Gravity is both an attractive force and a repelling force.
• Spinning objects are attracted to liquids. 

This graph shows the change in the force of gravity. The graph will never reach zero. Which statement BEST supports this hypothesis?

• Gravity cannot cross space.
• The force of gravity does not change regardless of distance.
• Every object exerts gravitational force on every other object.
• More distant objects exert a stronger gravitational force on other objects.

In order to launch a rocket into space, what must the rocket overcome?

• air resistance
• gravity
• friction
• magnetism

How is the spaceship's weight related to the moon?

• There is no gravity on the moon and therefore they are not related.
• As the spaceship gets closer to the moon, the weight of the spaceship increases.
• As the spaceship gets farther from the moon, the weight of the spaceship increases.
• The gravitational pull of the moon is constant and therefore the weight would not change. 

Which pair of objects demonstrate the SMALLEST gravitational pull?

• Objects of same mass 5 feet apart.
• Objects of same mass 10 feet apart.
• Objects of same mass 15 feet apart.
• Objects of small mass 20 feet apart.
