Physical Science Midterm Test Review

Front

What is the range of frequencies of light that the human eye can detect?

Back

The lowest frequency appears red, and the highest frequency appears violet.

Front

What happens to air particles when air is heated?

Back

The particles spread out and the warm air rises.

Front

What is the unit of measurement for work?

Back

Joules.

Front

In a circuit with multiple light bulbs, what happens if one bulb burns out?

Back

The other bulbs will keep working.

Front

What does an increasing slope on a position vs time graph indicate?

Back

It indicates that the object is moving away from the starting point at an increasing speed.

Front

What is the definition of frequency in the context of light?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is the relationship between temperature and particle movement in gases?

Back

As temperature increases, particle movement increases, causing particles to spread out.

Front

What is the formula for calculating work?

Back

Work = Force x Distance.

Front

What happens to the resistance in a circuit if more light bulbs are added in series?

Back

The total resistance increases, which can cause the bulbs to dim.

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement.
