Science SOL's 4.2 and 4.3

Front

What is potential energy?

Back

Potential energy is stored energy, or energy at rest.

Front

What is kinetic energy?

Back

Kinetic energy is energy in motion.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit that has two or more paths for electricity to flow.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where electricity flows in a single path.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily.

Front

How do different surfaces affect the amount of force needed to move a block?

Back

Different surfaces create varying amounts of friction, which affects the force needed to move an object.

Front

What did Michael Faraday discover about electric current?

Back

Michael Faraday discovered that electric current in a wire produces a magnetic field.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is the role of a spring scale?

Back

A spring scale measures the force exerted on an object, typically in units of weight.
