What force pulls objects toward the Earth?

Back

Gravity pulls objects toward the Earth.

Front

What are tides?

Back

Tides are the regular rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun.

What keeps the moon in orbit around the Earth?

Back

The gravitational pull of the Earth keeps the moon in its orbit.

How does gravity affect a skier on a mountain?

Back

Gravity pulls the skier down the mountain, causing them to accelerate downhill.

Front

What is the relationship between mass and gravity?

Back

The gravitational force between two objects increases with the mass of the objects and decreases with the square of the distance between them.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is a gravitational field?

Back

A gravitational field is a region of space around a mass where other masses experience a force of attraction.

Front

What role does gravity play in the formation of planets?

Back

Gravity pulls together gas and dust in space to form planets and other celestial bodies.
