What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms or grams.

How does gravity affect objects with mass?

Back

Gravity is a force that attracts two objects with mass towards each other. The more mass an object has, the stronger its gravitational pull.

What is the relationship between distance and gravity?

Back

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

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (Weight = Mass x Gravity).

What would happen to Earth if the Sun's gravity disappeared?

Back

Earth would drift into space without the Sun's gravitational pull to keep it in orbit.

Why do planets orbit the Sun?

Back

Planets orbit the Sun because it is the most massive object in our solar system, exerting the greatest gravitational pull.

What is the difference between mass and weight?

Back

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

What is the gravitational pull of the Moon compared to Earth?

Back

The Moon has a weaker gravitational pull than Earth, which is why objects weigh less on the Moon.

How does gravity affect falling objects?

Back

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