Gravitational Pull

Front

Who came up with the theory of gravity?

Back

Sir Isaac Newton is credited with formulating the theory of gravity.

Front

What size objects exert a stronger gravitational pull?

Back

Massive objects that are closer together exert a stronger gravitational pull.

Front

If the mass of your pet goldfish is 0.9 kg on Earth, how much will its mass be on the moon?

Back

The mass of the goldfish will still be 0.9 kg on the moon, as mass does not change with location.

Front

Gravitational Forces Are Always __________!

Back

Attractive. Gravitational forces always pull objects towards each other.

Front

What are the two factors that gravity depends on?

Back

Gravity depends on mass and distance between objects.

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

How does distance affect gravitational pull?

Back

The greater the distance between two objects, the weaker the gravitational pull between them.

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the 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 pull of Earth?

Back

The gravitational pull of Earth is approximately 9.81 m/s².

Front

What happens to gravitational pull if mass increases?

Back

If the mass of an object increases, the gravitational pull it exerts also increases.
