Gravity

Front

What happens to gravitational force as mass increases?

Back

Gravitational force increases.

Front

What is the SI unit used to measure force?

Back

Newtons.

Front

Which system has greater gravitational attraction between two objects?

Back

The system with the greater mass.

Front

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

Back

The Moon has less mass and therefore less gravity.

Front

Which system has greater gravitational pull between two objects?

Back

The system with the greater mass.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What is the gravitational constant (G)?

Back

G is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.
