## Short Notes for PHY101 Exams

### Scalars and Vectors

- Scalars are quantities that have only magnitude, while vectors have both magnitude and direction.
- Examples of scalars include distance, speed, and temperature, while examples of vectors include displacement, velocity, and force.

### Motion in One Dimension

- One-dimensional motion is motion along a straight line.
- The position of an object in one-dimensional motion is given by its displacement from a reference point.
- The average velocity of an object in one-dimensional motion is given by the change in position divided by the change in time.

### Newton’s Laws of Motion

- Newton’s first law of motion states that an object at rest will remain at rest unless acted upon by an external force.
- The Newton’s second law of motion states that the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.
- Newton’s third law of motion states that for every action, there is an equal and opposite reaction.

### Work, Energy, and Power

- Work is the transfer of energy from one object to another.
- Energy is the ability to do work and can exist in many forms, such as kinetic energy and potential energy.
- Power is the rate at which work is done and is given by the amount of work divided by the time it takes to do the work.

### Heat and Thermodynamics

- Heat is the transfer of thermal energy from one object to another due to a temperature difference.
- The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted from one form to another.
- The second law of thermodynamics states that the entropy of a closed system always increases over time.

### Waves and Optics

- Waves are disturbances that propagate through space and time.
- The speed of a wave is given by its wavelength multiplied by its frequency.
- Optics is the study of light and its interaction with matter.

### Electricity and Magnetism

- Electricity is the flow of electric charge through a conductor.
- The electric field is a vector field that describes the strength and direction of the force experienced by a charged particle.
- Magnetism is the force exerted by magnets on each other and on moving charges.

### Modern Physics

- Modern physics includes the study of quantum mechanics, relativity, and particle physics.
- Quantum mechanics is the study of the behaviour of matter and energy at the atomic and subatomic level.
- Relativity is the study of the laws of physics in the absence of gravity.

## Conclusion

PHY101 is a challenging but rewarding course that requires a lot of hard work and dedication to excel in. By practising problems, attending lectures, and forming study groups, you can prepare effectively for your exams. Hopefully, these short notes will help you revise the main concepts covered in the course and improve your performance in your midterm and final-term exams.
