## IB Physics Practice Questions

Here are some practice questions to test your knowledge and problem-solving skills in IB Physics:

### 1. Mechanics:

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.

### 3. Waves:

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.

### 6. Relativity:

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.

## Conclusion

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.
