Gravitational field strength equations review

As an object moves farther away from the Earth, the gravitational field strength will

• Decrease

• Increase

• Stay the same

What is a test body?

• Another word for experiment

• The name for the lines that we draw to represent a field

• Another name for a planet that is pulling other objects towards it

• Something that we can see experiences force due to the presence of a field

If I am doubling my distance from the Earth, my gravitational field strength will...

• Increase by a factor of 2

• Increase by a factor of 4

• Decrease by a factor of 2

• Decrease by a factor of 4

A spaceship has moved an unknown distance, and the gravitational field strength is now 1/16th of what it was before. Where is the spaceship now?

• The spaceship is four times farther away from the Earth

• The spaceship is sixteen times farther away from the Earth

• The spaceship is sixteen times closer to the Earth

At a given distance from Earth, the gravitational field strength is 5 N/kg. If an object moves 3 times farther away, what is the new gravitational field strength?

• 1.6 N/kg

• 15 N/kg

• 0.6 N/kg

• 2 N/kg

A cow has been abducted by aliens, and the UFO is hovering 8.25 x 10^6 m from the centre of the Earth. What is the gravitational field strength at this location (in N/kg, rounded to two decimal places)

You have been selected as the first person to go to mars, and the gravitational field strength on the surface of mars is 3.7 N/kg. If you weigh 200 kg with your spacesuit on, what force of gravity will you experience on the surface of mars? (in N)
