What happens to weight on different planets?

Back

Weight varies depending on the gravitational force of the planet. For example, a person weighing 100 pounds on Earth would weigh 260 pounds on Jupiter due to its strong gravitational force.

Front

What are the inner planets of the solar system?

Back

The inner planets are dense, rocky planets with few moons, including Mercury, Venus, Earth, and Mars.

Front

What is the shape of planetary orbits?

Back

All planets have elliptical orbits around the sun.

Front

What changes when an object goes to the Moon?

Back

An object's weight changes due to the different gravitational force on the Moon, but its mass remains the same.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, affecting weight based on mass and distance.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object and does not change, while weight is the force of gravity acting on that mass and can change depending on location.

Front

What is an asteroid?
