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

Does the size of an object affect its gravity?

Back

Yes, an object's gravity depends on its size (mass). Larger objects have a stronger gravitational pull.

Front

What happens to the pull of gravity as the distance between two objects increases?

Back

The pull of gravity decreases as the distance between two objects increases.

Front

Which planet has the shortest year?

Back

Mercury has the shortest year, taking about 88 Earth days to orbit the Sun.

Front

Can gravity be found on all objects?

Back

Yes, all objects with mass have gravity, including the Sun, buildings, and mountains.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

How does gravity affect weight?

Back

Weight is the force of gravity acting on an object. More gravity means more weight.

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

What is the gravitational pull of the Earth?

Back

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

Front

How does gravity affect the motion of planets?

Back

Gravity keeps planets in orbit around the Sun, preventing them from drifting away into space.
