Gravity and Orbits

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

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

Back

We weigh less on the Moon because it has less mass and therefore less gravity compared to Earth.

Front

What two factors affect the force of gravity between two objects?

Back

The two factors are mass and distance.

Front

What happens to your weight if Earth's mass is cut in half?

Back

Your weight would decrease because the gravitational force decreases.

Front

Does every object with mass have gravity?

Back

Yes, any object with mass has gravity.

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 distance affect gravity?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is the formula for 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 weight?

Back

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

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².
