Discover the fundamental laws of the universe
Physics is the science that seeks to understand how the universe works. From the smallest particles to the largest galaxies, physics explains the fundamental forces and laws that govern everything around us.
Key Areas of Physics:
🚗 Transportation: Cars use friction for braking, engines convert chemical energy to mechanical energy
📱 Technology: Smartphones use electromagnetic waves, touchscreens use electric fields
🏠 Home: Microwaves heat food with electromagnetic radiation, LED lights convert electricity to photons
⚽ Sports: Ball trajectories follow projectile motion, swimming uses fluid dynamics

Forces cause objects to accelerate. An object at rest stays at rest, and an object in motion stays in motion, unless acted upon by a force.
If a 2 kg object experiences a 6 N force, what is its acceleration?
Energy is the ability to do work. It comes in many forms and can be converted from one type to another.
A 0.5 kg ball is dropped from 2 meters. What is its kinetic energy just before hitting the ground? (g = 10 m/s²)
Waves transfer energy without transferring matter. They have properties like wavelength, frequency, and amplitude.
If a wave has frequency 5 Hz and wavelength 2 m, what is its speed?
Electric current is the flow of electric charge. Voltage pushes the current through resistance.
A circuit has 12V and 4Ω resistance. What is the current?
