Semester 1 Physical Science Review

Front

What type of heat transfer allows solar panels to absorb the sun's light energy?

Back

Radiation

Front

What is the flow of electricity through a conductor called?

Back

Current

Front

How do mass and weight change as a person moves around the universe?

Back

Mass stays constant, weight changes.

Front

Which wave has the greatest frequency in a diagram?

Back

Wave 4.

Front

What law explains why a balloon moves up when the air leaves the bottom?

Back

Newton's 3rd Law.

Front

What is the definition of conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is the definition of voltage?

Back

Voltage is the electric potential difference between two points in a circuit.

Front

What is resistance in an electrical circuit?

Back

Resistance is the opposition to the flow of electric current.

Front

What is the relationship between frequency and wavelength in waves?

Back

Frequency is inversely proportional to wavelength; as frequency increases, wavelength decreases.
