Front

What is gravity?

Back

Gravity is a type of force that attracts two bodies towards each other.

Front

How does the sun's gravity compare to Earth's gravity?

Back

The sun's gravity is stronger than Earth's gravity.

Front

What happens to the Earth's gravitational pull if its orbit moves farther away from the Sun?

Back

The Sun's gravitational pull on the Earth would decrease.

Front

According to Einstein, what does gravity do to space and time?

Back

Gravity bends space and time.

Front

What two factors does gravity depend on?

Back

Gravity depends on mass and distance.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the effect of distance on gravitational force?

Back

The greater the distance between two objects, the weaker the gravitational force between them.

Front

What is Newton's law of universal gravitation?

Back

It states that every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is an example of gravity in everyday life?

Back

An example of gravity is when an apple falls from a tree to the ground.

Front

How does gravity affect the motion of planets?

Back

Gravity keeps planets in orbit around the Sun.
