IB Physics Practice Questions
Here are some practice questions to test your knowledge and problem-solving skills in IB Physics:
a) A ball is thrown vertically upward with an initial velocity of 20 m/s. Calculate the maximum height it reaches. (Assume no air resistance.)
b) A car is traveling at a constant speed of 30 m/s. If the driver suddenly applies the brakes, and the car comes to a stop in 5 seconds, what is the car's acceleration?
2. Electricity and Magnetism:
a) Two resistors, R1 and R2, are connected in series. If R1 = 4 ohms and R2 = 6 ohms, what is the total resistance in the circuit?
b) In an electromagnetic wave, the electric field oscillates at a frequency of 60 Hz. Calculate the wavelength if the speed of light is approximately 3 x 10^8 meters per second.
a) A wave has a frequency of 400 Hz and a wavelength of 0.5 meters. Calculate the wave's speed.
b) When light passes from air into glass, its speed decreases. Explain how this affects the angle of refraction.
4. Modern Physics:
a) Calculate the energy of a photon with a frequency of 5 x 10^14 Hz.
b) Describe the photoelectric effect and explain how it supports the idea of quantized energy levels.
5. Nuclear Physics:
a) In a nuclear reaction, uranium-235 decays to thorium-231 by emitting an alpha particle (helium nucleus). Write the balanced nuclear equation for this reaction.
b) Explain the process of nuclear fission and provide an example of its application.
a) State the two postulates of special relativity as proposed by Albert Einstein.
b) A spaceship is traveling at 90% of the speed of light relative to an observer on Earth. Calculate the time dilation factor (γ) for the spaceship.
IB Physics is a challenging course that requires a strong understanding of fundamental physics concepts and the ability to apply them to a variety of problems. Utilizing the right revision resources and practicing with a range of questions will help you prepare effectively for your IB Physics exams. Consistency in your study routine and a clear understanding of the syllabus topics and their applications are essential for success in IB Physics.
