Gravity

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

True or False: Any object with mass has gravity.

Back

True

Front

What determines the strength of gravitational pull between two objects?

Back

The strength of gravitational pull is determined by the masses of the objects and the distance between them.

Front

Which has a greater gravitational pull: a small object or a large object?

Back

A large object has a greater gravitational pull due to its greater mass.

Front

Why do astronauts weigh less on the Moon than on Earth?

Back

Astronauts weigh less on the Moon because the Moon has less mass and therefore less gravity.

Front

What is the relationship between mass and weight?

Back

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

Front

What happens to gravity as distance increases?

Back

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

Front

What is the formula for calculating gravitational force?

Back

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

Front

True or False: The Earth has a gravitational pull on the Moon.

Back

True

Front

What is the gravitational pull of the Earth on an object at its surface?

Back

The gravitational pull of the Earth on an object at its surface is approximately 9.8 m/s².
