Everything in the solar system revolves around the Sun because of:

• The Sun's gravitational pull

• The Sun's magnetic field

• The Sun's light

• The Sun's heat

What 2 factors affect an object's gravitational pull?

• Mass and distance

• Volume and temperature

• Speed and direction

• Color and texture

What happens to the gravitational pull of an object if its mass is doubled?

• The gravitational pull is halved.

• The gravitational pull remains the same.

• The gravitational pull is doubled.

• The gravitational pull is quadrupled.

What is the difference between weight and mass?

• Weight is the force exerted by gravity on an object, while mass is the amount of matter in an object.

• Weight and mass are the same and can be used interchangeably.

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

• Weight is measured in kilograms, while mass is measured in newtons.

If I go to the moon, what will happen to my weight and why? My mass?

• Your weight will decrease because the moon's gravity is weaker, but your mass will remain the same.

• Your weight will increase because the moon's gravity is stronger, but your mass will remain the same.

• Both your weight and mass will decrease because the moon has no gravity.

• Both your weight and mass will increase because the moon has more gravity.
