Gravitational Field Strength Vocabulary

What is the definition of gravitational field strength?

• Energy stored in a gravitational field.

• Distance between two masses in a gravitational field.

• Gravitational force exerted on an object per unit mass.

• Acceleration experienced by a unit mass placed in a gravitational field.

What are the units of gravitational field strength?

• N/kg

• kg/m

• J/kg

• m/r²

How do you calculate gravitational field strength?

• Gravitational field strength is calculated by dividing the force of gravity acting on an object by the mass of the object.

• Gravitational field strength is calculated by adding the force of gravity acting on an object to the mass of the object.

• Gravitational field strength is calculated by subtracting the force of gravity acting on an object from the mass of the object.

• Gravitational field strength is calculated by multiplying the force of gravity acting on an object by the mass of the object.

What is the gravitational field strength on Earth?

• 11 N/kg

• 10 N/kg

• 9 N/kg

• 8.9 N/kg

How does gravitational field strength relate to weight?

• Inversely proportional

• Unrelated

• Exponentially proportional

• Directly proportional

How does gravitational field strength change with distance?

• increases

• remains constant

• fluctuates

• decreases

Mass is defined as

• the amount of matter in an object

• the gravitational pull of an object anywhere

• the forces exerted on an object in a gravitational field

• the weight of an object

the ​ (a)   of an object is ​ ​ (b)   proportional to its ​ (c)   and the ​ (d)   exerted on it.

• weight
• directly proportional
• gravitational field
• gravity
• mass
• directly
• inversely

If we know the ​ (a)   and ​ (b)   of a planet, we can use these quantities to calculate the ​ (c)   on that planet.

• mass
• radius
• strength of gravity
• weight
• size

If the gravitational field strength on Planet X is 11 N/kg and on Planet Y it is 7 N/kg where would you be the most massive?

• Planet X

• Planet Y

• Be the same on both planets
