Gravity

Front

What is the definition of Gravity?

Back

The force of attraction that pulls objects towards each other because of their masses.

Front

Why would a person weigh less on the Moon than on Earth?

Back

Because the Moon has less mass and therefore less gravity.

Front

Does mass vary depending on where the object is located?

Back

False.

Front

Which system has the greater gravitational pull between two objects?

Back

The system with the greater mass.

Front

Which model displays the most gravitational force of attraction?

Back

The model with the largest mass and closest distance between objects.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with greater mass.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between objects increases.

Front

What is 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.
