A-Level Physics Quiz

What is the primary goal when showing that an equation is homogeneous?

• To simplify the equation for easier calculation

• To convert all units to metric

• To ensure the equation is dimensionally consistent

• To find the numerical value of constants

Why is the resultant force on the glider given by F = 2kx?

• Because both springs are compressed equally

• Because the forces from both springs add up

• Because the glider is moving at constant speed

• Because the springs have different constants

What is the effect of increasing the initial displacement on the time period in simple harmonic motion?

• It doubles the time period

• It has no effect on the time period

• It increases the time period

• It decreases the time period

What is one common error in data tables that needs correction?

• Excessive data points

• Incorrect graph labels

• Inconsistent significant figures

• Missing data points

When plotting a graph, why is it important to have a fair distribution of points around the line of best fit?

• To accurately represent the data trend

• To ensure the graph is symmetrical

• To make the graph look neat

• To avoid errors in calculation

How is the spring constant 'k' determined from the graph?

• By measuring the slope of the line of best fit

• By calculating the area under the curve

• By finding the intercept on the y-axis

• By comparing it to a standard value

What happens to the potential energy when the initial displacement is increased?

• It remains constant

• It increases

• It decreases

• It becomes zero

Why does the maximum kinetic energy increase when the amplitude increases?

• Because the spring constant changes

• Because the mass of the glider increases

• Because the time period decreases

• Because the potential energy is converted to kinetic energy

What is the relationship between maximum velocity and amplitude in simple harmonic motion?

• Maximum velocity increases with amplitude

• Maximum velocity is independent of amplitude

• Maximum velocity decreases with amplitude

• Maximum velocity is inversely proportional to amplitude

In simple harmonic motion, what remains constant when the amplitude changes?

• The potential energy

• The time period

• The maximum velocity

• The spring constant
