A-Level Physics Paper 3 Quiz

What is the initial scenario described in the problem involving the motorcyclist?

• A motorcyclist performing stunts.

• A motorcyclist racing on a track.

• A motorcyclist stopping on a level track.

• A motorcyclist accelerating on a hill.

What is the formula used to calculate the stopping distance?

• s = ut + 0.5at^2

• v^2 = u^2 - 2as

• v = u + at

• v^2 = u^2 + 2as

Why is plotting a graph of d/v against v considered a sensible decision?

• It results in a quadratic curve.

• It results in a hyperbolic curve.

• It results in a straight line through the origin.

• It results in a parabolic curve.

How is the percentage uncertainty in d/v calculated?

• By dividing the uncertainties.

• By adding the percentage uncertainties of D and V.

• By multiplying the uncertainties.

• By subtracting the uncertainties.

What is the significance of the gradient in the graph of d/v against v?

• It represents the thinking distance.

• It represents the acceleration.

• It represents the initial speed.

• It represents the breaking distance.

What does the intercept of the graph represent in this context?

• The breaking distance.

• The thinking distance.

• The final speed.

• The initial speed.

How does a zero error affect the results in this experiment?

• It lowers the intercept value.

• It decreases the gradient.

• It raises the intercept value.

• It increases the gradient.

What is the calculated acceleration from the graph?

• 8.3 m/s²

• 7.7 m/s²
