What is the term for the minimum speed needed for an object to break free from a planet's gravitational pull?

Back

Escape velocity

Front

What is the measure of the amount of matter in an object?

Back

Mass

Front

When will the gravitational forces between two objects be the greatest?

Back

When the masses of both objects are large and the objects are close together.

Front

Which system has a greater gravitational pull between two objects?

Back

The system with the larger mass.

Front

What is the relationship between mass and weight?

Back

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

Front

What is the formula for calculating weight?

Back

Weight = Mass × Gravitational Acceleration (W = m × g)

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is the universal law of gravitation?

Back

Every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is the difference between mass and weight?

Back

Mass is a measure of matter, while weight is the force exerted by gravity on that mass.
