It is a very vague question but practically everything we do in our daily lives involves SOME degree of physics.
1) When we walk or run, our motion is part of the laws of mechanics and thermodynamics.
2) We eat food that undergoes chemical reactions producing heat energy which is converted into mechanical energy.
3) Use of refrigerators, pressure cookers, washing machines, vacuum cleaners, television, music systems, computers, etc. are all designed on the principles of physics.
4) When we speak, we produce sound properties of which like pitch and intensity are studied in physics.
5) Electricity that we use in households is a gift of physics.
6) Automobile design is based on physics.
The list is endless.
Putting on a toaster, boiling a kettle – heat energy, electricity
Cycling a bike – mechanical movements
Using the brakes – friction
Using a door handle – levers and springs
Throwing a ball – weights, gravity, trajectory, air resistance
1)We walk, walk fast, run, jog, jump into a bus or ride a car or a bike, etc.
All these or any type of motion are associated with Newton’s law of motion.
2) When we talk, our vocal cords vibrate producing sound.
3) When we eat food, the chemical energy of the food is being converted into mechanical energy which we use to do different types of work.
4) The electricity we use in our houses is a gift of Physics. A hydroelectric project is a method by which water is used to generate electricity. The mechanical energy of the water is converted into electrical energy using a dynamo.
