PS Final Exam Review

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

Which wave has the greatest wavelength?

Back

The wave with the longest distance between crests.

Front

What does a graph showing constant speed look like?

Back

A straight line with a constant slope.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is resistance in a circuit?

Back

Resistance is a measure of how hard it is for electrons to move through the circuit.

Front

What unit is used to measure force?

Back

Newtons (N) are used to measure force.

Front

What happens to an object when it accelerates?

Back

It changes its speed or direction.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = m × a).

Front

What is the relationship between voltage, current, and resistance?

Back

Ohm's Law states that Voltage = Current × Resistance (V = I × R).

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time.
