Forces and Simple Machines
This force is an application of Newton's 3rd law of motion. It always applies in the opposite direction of motion between two surfaces.
What is friction?
This separation technique occurs when a liquid is heated, turned into a gas, and removed from a mixture.
What is evaporation?
This is the name for hot molten rock found under the surface of the Earth.
What is magma?
These are the three main sub-atomic particles.
What are protons, neutrons, and electrons?
What is potential energy?
This is the continuous, cyclical path that an object in space takes around a larger object in space.
What is an orbit?
This pair of simple machines allows for ease of movement, decreased friction, and can be found in everything from cars, trains, and buses.
What is a wheel and axle?
This separation technique, often used when making coffee, separates larger particles from smaller particles by trapping them with a piece of paper or metal.
What is filtration?
These are the three main types of rocks.
What are igneous, sedimentary, and metamorphic?
These two subatomic particles are found inside of the nucleus of an atom.
What are protons and neutrons?
Electrical, acoustic, and mechanical are types of this form of moving energy.
What is kinetic energy?
What are Earth, Venus, Mars, and Mercury? (in that order).
This force is the force of attraction between the center of mass of any two objects in the universe.
What is gravity?
What is sublimation?
These remains of plants and animals can be found only in sedimentary rocks trapped under layers of soil run-off and compressed for thousands of years.
What are fossils?
This group of elements on the periodic table are inert, or completely nonreactive, with all other elements in the periodic table.
What are the noble gases?
These types of circuits have the ability to split the current running through them, but lose the same amount of voltage across each resistor.
What are parallel circuits?
The competition between the United States and Russia (USSR) between approximately 1956-1980 that created the space programs for both countries and pushed technological development of rockets and satellites.
What was the space race?
These are the three main parts of a lever.
What are the effort, the load, and the fulcrum?
This is the general chemical name for a solid substance left behind during separation.
What is a precipitate?
These large pieces of the Earth's crust are constantly in motion, floating on top of the mantle.
What are tectonic plates?
This atomic model shows protons and neutrons in a nucleus surrounded by electrons in orbitals.
What is the Bohr model?
What is the law of reflection?
This was the name of the very first satellite launched into orbit in 1957.
What was Sputnik?
In a single moveable pulley system, when the effort pulls UP on one end of the pulley, the load moves in this direction.
What is up?
This separation technique, often used in food preservation, removes all the water from food without using heat.
What is freeze-drying?
These types of waves move like a pulse and are the first waves created by earthquakes when two plates collide.
What are longitudinal waves (or P-waves)?
This is the name for an atom with an unequal number of protons and neutrons.
What is an ion?
This equation demonstrates the relationship between voltage, current, and resistance within a circuit.
What is Ohm's Law?
This was the first person to travel into space.
Who was Yuri Gagarin?
