Gravitational Field

What is gravity?

• A type of energy that objects emit

• The natural tendency for things to move towards massive objects

• A force that repels objects away from each other

• The speed at which objects fall to the ground

Does the Moon have its own gravity?

• No, gravity only exists on Earth

• Yes, but only during a full moon

• Yes, because it has mass

• No, because it orbits the Earth

Can smaller objects have a gravitational pull?

• No, only planets and stars can have a gravitational pull

• Yes, but only if they are made of metal

• Yes, all objects with mass have some form of gravitational pull

• No, gravity is a property of the Earth's core only

How does the gravitational force between two objects change if the distance between them is halved?

• It doubles

• It quadruples

• It halves

• It remains the same

What would happen to the gravitational force between two objects if one of their masses doubled?

• The gravitational force would double

• The gravitational force would halve

• The gravitational force would remain unchanged

• The gravitational force would quadruple

In this equation...

• G is the gravitational field strength
• r is the distance between the 2 masses
• F is the repulsive gravitational force
• m is the momentum of the mass

The definition of gravitational field strength is:

• The region of space surrounding a body where other bodies will feel an attractive force due to it.
• The region of space surrounding a body where other bodies will feel an repulsive force due to it.
• The region of space surrounding a charge where other charges will feel an attractive force due to it.
• The region of space surrounding a charge where other charges will feel an repulsive force due to it.
