Why do the planets and other celestial objects in our solar system revolve around the Sun?
The Sun has the greatest mass of any object in the solar system and therefore the greatest gravity
The sun is the center of the universe
The sun is the brightest thing in space and everything is attracted to it.
The Sun has the greatest weight so everything pushes towards it
Large mass of stars
Solar System
Galaxy
Nebula
Milky Way
The gravitational force between two objects can be very small, unless which of the following is true?
The objects must be very far apart.
One of the objects must have a very large mass.
Both objects must have very large masses.
Both objects must be in the solid state of matter.
If you landed on Mars, what happens to your mass and weight? Remember the force of gravity on Mars is less than on Earth.
The mass decreases while the weight stays the same.
The mass stays the same while the weight increases.
The mass increases while the weight decreases.
The mass stays the same while the weight decreases.
Which piece of evidence best supports this statement: Gravity is felt between objects across a distance.
Heavier objects have less gravity acting on them.
An object at rest on the ground doesn’t respond to gravity.
The Moon orbits Earth due to a gravitational field.
Objects float freely in space where there is no gravity.
Gravity is responsible for which of the following characteristics of a galaxy?
The motion of the objects within it
The size of its largest stars
Its location within the universe
The color of light it emits
Which of the following best describes the formation of the solar system?
The Sun ejected rocky material which formed the planets due to magnetic attraction forces.
A rotating disk of gas and dust was drawn together by the force of gravity.
One very large planetary body broke apart into several smaller planets.
Several stars of different masses cooled and formed the planets and the Sun.
Earth and its solar system are a part of which of the following galaxies?
Three Musketeers
Snickers
Twix
Milky Way
Why do some planets have moons in our solar system?
They are close to the sun
