Gravity and Tides

Front

What is gravity?

Back

Gravity is the force of attraction between all objects that have mass.

Front

Which object has the strongest gravitational pull based on mass?

Back

The Sun has the strongest gravitational pull because it has the most mass.

Front

What is mass?

Back

Mass is the amount of matter in an object.

Front

What is weight?

Back

Weight is the measure of the force of gravity acting on an object.

Front

Which has weaker gravity: two small objects that are far apart or two large objects that are close together?

Back

Two small objects that are very far away have weaker gravity.

Front

What factors affect the strength of gravity?

Back

The strength of gravity is affected by the mass of the objects and the distance between them.

Front

What is the relationship between mass and gravity?

Back

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

Front

How does distance affect gravitational pull?

Back

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

Front

What is the gravitational pull of Earth?

Back

Earth's gravitational pull is what keeps us and everything else on its surface.

Front

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 on that mass.
