Gravity Review

Front

What is the formula for calculating weight?

Back

W = m x g, where W is weight, m is mass, and g is the acceleration due to gravity.

Front

How can you increase the gravitational force acting on an object?

Back

By increasing the mass of the object.

Front

If an object has a mass of 30 kg on Earth, what would its mass be on the Moon?

Back

Its mass would still be 30 kg, as mass does not change with location.

Front

What role does the Sun's gravitational pull play in the solar system?

Back

It keeps planets orbiting around it.

Front

If the weight of an object is 100 N and the gravitational acceleration is 9.8 m/s², how do you calculate its mass?

Back

Use the formula m = W/g, which gives m = 100 N / 9.8 m/s² = 10.2 kg.

Front

What is the value of gravitational acceleration on Earth?

Back

Approximately 9.8 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What happens to the weight of an object if you take it to a planet with stronger gravity?

Back

The weight of the object will increase due to the stronger gravitational pull.

Front

What is the gravitational force between two objects dependent on?

Back

It depends on the masses of the objects and the distance between them.

Front

What is the gravitational force formula?

Back

F = G * (m1 * m2) / r², 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.
