Physical Science Final Exam Review

Front

What is the formula to calculate the speed of a wave?

Back

Speed = Frequency × Wavelength

Front

How many valence electrons does an element in group 16 have?

Back

6 valence electrons

Front

What happens when unequal and opposing forces are applied to an object?

Back

The object will move in the direction of the greater force.

Front

What is net force?

Back

The overall force acting on an object, taking into account all individual forces.

Front

How do you calculate the number of neutrons in an atom?

Back

Number of Neutrons = Atomic Mass - Atomic Number

Front

What is the relationship between frequency and wavelength in a wave?

Back

They are inversely related; as frequency increases, wavelength decreases.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the significance of the atomic number of an element?

Back

It represents the number of protons in the nucleus and defines the element.
