Gravity and Space

Front

What is the difference between weight and mass?

Back

Mass is the amount of matter in an object, and weight is the gravitational force exerted on an object.

Front

What happens to the planets if the sun’s gravitational force disappears?

Back

They will fly away in straight lines.

Front

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

Back

Your weight will decrease because gravitational force decreases.

Front

An object's weight is a result of the force of __________ at work.

Back

Gravity.

Front

Your mass increases on a large planet with more gravity. True or False?

Back

False.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, depending on their masses and the distance between them.

Front

How does gravity affect objects in space?

Back

Gravity keeps planets in orbit around stars and moons in orbit around planets.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Gravitational Acceleration (W = m x g).

Front

What is the gravitational force on the Moon compared to Earth?

Back

The gravitational force on the Moon is about 1/6th that of Earth.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.
