Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two objects towards each other, depending on their masses and the distance between them.

Front

What determines the strength of gravitational attraction?

Back

The strength of gravitational attraction is determined by the masses of the objects and the distance between them.

Front

What is mass?

Back

Mass is how much matter makes up an object.

Front

What is weight?

Back

Weight is the gravitational force between an object and the Earth.

Front

Why do objects fall to the ground?

Back

Objects fall to the ground because Earth's force of gravity is greater than the force of gravity acting on the object.

Front

What happens to gravity as distance increases?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

Do astronauts experience gravity in space?

Back

Yes, astronauts experience gravity in space, but it is weaker than on Earth.

Front

Why do astronauts float on the ISS?

Back

Astronauts float on the ISS because they are in a state of free fall, experiencing less gravitational force.

Front

What is the relationship between mass and weight?

Back

Weight is the product of mass and the acceleration due to gravity (Weight = Mass x Gravity).

Front

What is the gravitational force between two objects?

Back

The gravitational force is the attraction that pulls two objects toward each other.
