Gravity in the Solar System

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

What affects the strength of gravity?

Back

The strength of gravity is affected by mass and distance.

Front

What happens to gravity as distance increases?

Back

As distance increases, the strength of gravity decreases.

Front

What happens to gravity as mass increases?

Back

As mass increases, the strength of gravity increases.

Front

What keeps planets in orbit around the sun?

Back

The gravitational pull of the sun keeps planets in orbit.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does inertia relate to gravity in the solar system?

Back

Inertia helps keep planets moving in their orbits, while gravity pulls them towards the sun.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

Which has more gravity: a small object or a large object?

Back

A large object has more gravity than a small object.

Front

What would happen if the sun suddenly disappeared?

Back

If the sun disappeared, the planets would no longer be held in orbit and would move in a straight line due to inertia.
