What is the primary purpose of equations in physics as described in the text?

• To create complex mathematical problems

• To describe relationships between two physical variables and predict changes

• To measure time accurately

• To define the laws of motion

Which of the following equations represents an inverse relationship?

• y = x + 1

• y = 2x

• y = 1/x

In the equation y = m√x, what does 'm' represent?

• A constant value

• A variable that changes with x

• The square root of y

• The square of x

What happens to variable A if variable B increases in a direct square root relationship?

• Variable A decreases significantly

• Variable A remains constant

• Variable A increases but not by much

• Variable A increases significantly

What type of relationship is depicted in the graph shown?

• Direct linear relationship

• Inverse square relationship

• Direct square root relationship

• Exponential relationship

What is a direct square relationship?

• When the arrows in the equation point in opposite directions, and one of the variables is squared.

• When the arrows in the equation point in the same direction, and one of the variables is squared.

• When the arrows in the equation point in the same direction, and none of the variables is squared.

• When the arrows in the equation point in opposite directions, and none of the variables is squared.

What is a constant relationship in a graph?

• When the vertical-axis variable changes constantly

• When the vertical-axis variable doesn't change at all

• When both axes change at the same rate

• When the horizontal-axis variable doesn't change at all
