Simple Machines
a bar that pivots around a fixed point.
What is a lever?
What are non-magnetic materials?
tiny particles that are a part of atoms
What is an electron?
Energy possessed by an object based on motion or position.
What is mechanical energy?
A push, pull, twist or turn.
What is a force?
A device that is thick at one end and tapers to a thin edge at the other end
What is a wedge?
A small magnetic item that has can tell direction
What is a compass?
power source, wires, switch and load.
What are the components of a circuit?
Energy that would always be available to use.
What is renewable energy?
Keeps us on the ground and gives us weight.
What is gravity?
basic mechanical devices that help make work easier by allowing us to push or pull over increased distances. They have few or no moving parts and use mechanical advantage to multiply force.
What are simple machines?
a magnet that uses an electrical current.
What is an electromagnet?
the flow of electrical power or charge.
What is electricity?
energy cannot be created or destroyed, only transformed from one form to another.
What is the law of conservation of energy?
H2O
What is the chemical symbol for water?
Allow heavy objects to be raised without lifting them straight up, reducing the amount of force needed
What is an inclined plane
the force exerted by magnets when they attract or repel each other.
What is magnetism?
a path in which electricity flows
What is a circuit?
a measure of how effectively energy is converted from one form to another in a system.
What is efficiency?
This happens when water changes from a liquid to a gas.
What is evaporation?
Change the direction of a force, making it easier to lift heavy objects.
What is a pulley?
The area around a magnet where magnetic forces can be felt.
What is a magnetic field?
materials that either allow or not allow electricity to flow through it.
Kinetic, potential, chemical, nuclear, thermal, etc.
What are the different forms of energy?
At 1000C this liquid changes states.
What is the boiling point of water?
