Physic Paper 2 Revision Questions v.3

A student investigates a pendulum.

He measures the time for the pendulum to complete 20 oscillations.

He repeats the experiment three more times.

The readings are shown. What is the average period of the pendulum?

• 0.88 s

• 0.92 s

• 17.6 s

• 18.4 s

A tennis ball falls from the upstairs window of a house. What can be said about the acceleration of the ball if air resistance is ignored?

• It depends on the density of the ball.

• It depends on the mass of the ball.

• It increases as the ball falls.

• It stays the same as the ball falls.

A car joins a road at a speed of 14 m / s and accelerates at 4.0 m / s^2 for 5.0 seconds.

What is the final speed of the car?

• 18 m/s

• 20 m/s

• 32 m/s

• 34 m/s

The gravitational field strength is 8.8 N / kg on Venus and 3.8 N / kg on Mars.

An object has a weight of 42 N on Venus.

What are the mass and the weight of the object on Mars?

• mass (kg) = 4.8 | weight (N) = 18

• mass (kg) = 4.8 | weight (N) = 42

• mass (kg) = 11 | weight (N) = 42

• mass (kg) = 11 | weight (N) = 97

A student carries out an experiment to find the density of a rock. Which two measurements does the student need to make to determine the density of the rock?

• measurement 1: increase in mass | measurement 2:

  increase in volume of liquid

• measurement 1: final mass | measurement 2:

  increase in depth of liquid

• measurement 1: increase in mass | measurement 2:

  increase in depth of liquid

• measurement 1: final mass | measurement 2:

  increase in volume of liquid

A car has a mass of 1500 kg. A constant resultant force acts on the car and the car accelerates

from 15 m / s to 20 m / s in 4.0 seconds.

What is the magnitude of the resultant force acting on the car?

• 300 N

• 1200 N

• 1900 N

• 7500 N

A metal wire is loaded up to the limit of proportionality.

Which statement is correct?

• Hooke’s law is not obeyed when the load is increased from zero to this point.

• When the load is increased beyond the limit of proportionality, the diameter of the wire will

  increase.

• When the load is removed, the wire returns to its original length.

• Up to the limit of proportionality, there is no change in the shape of the wire.

The diagram shows a uniform metre rule, MN, pivoted at its midpoint P. Two weights, W1 and W2, are hung either side of the pivot.

The rule remains balanced.

Which is correct?

• direction of resultant

  moment about point M = clockwise | direction of resultant

  force on the rule = downwards

• direction of resultant

  moment about point M = clockwise | direction of resultant

  force on the rule = zero

• direction of resultant

  moment about point M = zero | direction of resultant

  force on the rule = downwards

• direction of resultant

  moment about point M = zero| direction of resultant

  force on the rule = zero

Which physical quantity is a vector?

• mass

• density

• temperature

• velocity

A resultant force of 500 N acts for 10 s on a car of mass 1000 kg. This causes the velocity of the

car to double.

What is the final velocity of the car?

• 5 m/s

• 10 m/s

• 20 m/s

• 50 m/s
