Science Study Guide- Gravity Exam
questions with correct answers
In your own words, write a definition for the term GRAVITY. - correct answer -Force of attraction
between objects.
Use each of the following words in a separate sentence: Mass and Gravity - correct answer -Gravity is a
result of mass. Weight is measured by a springscale
If Earth's mass doubled without changing its size, your weight would...? - correct answer -Increase
because gravitational force increases
What is the law of gravitational forces? - correct answer -All objects in the universe attract each other
because of gravitational force
How does the mass of an object relate to the gravitational force that the object exerts on other objects?
- correct answer -Gravitational force increases as mass increases.
How does the distance between objects affect the gravitational force between them? - correct answer -
The more distance the less gravitational pull. The less distance the more gravitational force.
Why are mass and weight often confused? - correct answer -Weight is related to mass but weight
changes when gravity changeds. Mass always stays the same.
The gravitational force on Jupiter is approximately 2.3 times the gravitational force on Earth. If an object
has a mass of 70 kg and a weight of 686 N on Earth, what would the object's mass and weight on Jupiter
be? - correct answer -Multiply the weight of Earth (686N) by 2.3 to get the weight. Mass stays the same.
Weight=1,577.8 N
Mass= 70 kg
