Row 1
A natural or artificial body that revolves around a celestial body that is greater in mass
What is a Satellite?
An event in which the shadow of one celestial body falls on another
What is an eclipse?
The spin of a body on its axis.
What is rotation?
The path that a body follows as it travels around another body in space
What is orbit?
a force of attraction between objects that is due to their masses.
What is gravity?
Earth’s gravity pulls harder on objects with what?
What is more mass?
The sun has the mass of over _____300,000___________________ what????
What is Earths?
Whose gravity is weaker, the moon’s or the Earth’s?
What is the Moon's gravity?
Every person and object in the universe has its own what?
What is gravity?
The moon’s gravity causes the water in the oceans to do what?
What is rise and fall twice a day?
The first scientist to mathematically describe how the force of gravity behaved?
Who was Sir Isaac Newton?
The different appearances of the moon from Earth throughout the month are called the
What are Lunar Phases?
The time required for Earth to orbit once around the sun
What is a year?
This system consists of the sun and bodies that move in orbit around it.
What is the Solar System?
Changes in the ocean water levels are known as
What are tides?
A division of the year that is characterized by recurring weather conditions and determined by both Earth’s tilt relative to the sun and Earth’s position in its orbit around the sun
What is a season?
The motion of a body that travels around another body in space; one complete trip along an orbit
What is a Revolution?
The inward force required to keep a particle or an object moving in a circular path.

The topic you most liked learning about in Science this year
What is....................whatever you liked learning most about in Science this year!!
In the orbit of a planet or other body in the solar system, the point that is CLOSEST to the sun
What is Perihelion?
In the orbit of a planet or other body in the solar system, the point that is FARTHEST from the sun
What is Aphelion?
a law that states that ALL objects in the universe attract each other through gravitational force.
What is the law of universal gravitation?
The strength of the force of gravity depends on the product of the masses of two objects. Therefore, as the masses of two objects increase, the force that the objects exert on one another does what?
What is increases?
Gravitational force is inversely proportional to the square of the distance between two objects. Therefore, as the distance between two objects increases, the force of gravity between them does what?
What is decreases?
