Magnetism Basics
Gravity in Space
Energy and Forces
Solar System Gravity
Attraction and Repulsion
100
This is the force that pulls opposite poles of magnets together.
What is attraction?
100
This planet in our solar system has the strongest gravitational pull.
What is Jupiter?
100
This type of energy is stored in an object due to its position.
What is potential energy?
100
This celestial body has a gravitational pull strong enough to hold the Moon in orbit.
What is the Earth?
100
This happens when like poles of two magnets are brought close together.
What is they repel?
200
This is the invisible area around a magnet where magnetic forces act.
What is a magnetic field?
200
This force keeps planets in orbit around the Sun.
What is gravity?
200
This happens to potential energy when an object falls.
What is it converts to kinetic energy?
200
This celestial body that is a spherical World but has the smallest gravitational pull in our solar system.
What is Ceres?
200
This type of force pulls objects toward each other due to gravity.
What is attractive force?
300
This happens to the magnetic field when the current in a wire increases.
What is it becomes stronger?
300
This planet in the solar system has the weakest gravity.
What is Mercury?
300
This type of energy is used to move objects in a magnetic field.
What is kinetic energy?
300
Astronauts experience weightlessness on the ISS because of this.
What is Free fall around the Earth?
300
This is the difference between a magnetic field and a gravitational field.
What is a magnetic field affects magnetic materials; a gravitational field affects all objects with mass?
400
This is the process of aligning magnetic domains in a material to make it magnetic.
What is magnetization?
400
This describes the relationship between mass and gravitational pull.
What is greater mass equals stronger gravitational pull?
400
This happens to the force of attraction between two magnets as the distance between them increases.
What is it decreases?
400
This is how the Sun’s gravity affects the orbits of planets.
What is it keeps them in elliptical orbits?
400
This determines whether a magnet attracts or repels another object.
What is the orientation of the poles?
500
This type of energy is associated with the movement of magnets or objects in their field.
What is kinetic energy?
500
These are the two factors that determine the strength of gravity between two objects.
What are mass and distance?
500
This type of energy is stored in a battery.
What is chemical energy?
500
This would happen to a planet’s orbit if the Sun’s gravity suddenly disappeared.
What is it would fly off in a straight line?
500
The Earth’s core contributes to its magnetic field because of this.
What is the movement of molten iron and nickel?
