Gravity and Orbits

Front

What is gravity?

Back

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

Front

Why do objects weigh less on the Moon than on Earth?

Back

Objects weigh less on the Moon because the Moon has less mass and therefore less gravity compared to Earth.

Front

What happens to your weight if Earth's mass is cut in half?

Back

Your weight would decrease because the gravitational force would decrease.

Front

What keeps planets in orbit around the Sun?

Back

Gravity is the force that keeps planets in orbit around the Sun.

Front

What would happen to objects in the universe without gravity?

Back

Without gravity, stars, planets, and all objects would move in a straight line instead of orbiting each other.

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 gravitational force decreases as the distance between two objects increases.

Front

What is an orbit?

Back

An orbit is the curved path that an object takes around another object due to gravitational attraction.

Front

What is the difference between weight and mass?

Back

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

Front

How does gravity affect falling objects?

Back

Gravity causes all objects to fall towards the Earth at the same rate, regardless of their mass.
