Question

Write any 5 examples of principles of science that you observe in your daily life with explanation For eg. Floating of plastic ball in water is due to buoyant force and density​

Answer 1

Answer: 1: A POWER DRILL COULD SET YOUR HOUSE ON FIRE, IN THEORY.

POWER DRILL COULD SET YOUR HOUSE ON FIRE, IN THEORY.Because of friction, electric drills generate heat.

2: STICKY NOTES COME OFF EASILY BECAUSE THEIR ADHESIVE IS UNEVEN.

Post-it Notes feature a plastic adhesive that is spread out in blobs across the paper.

Answer 2

Answer:

${ \large{ \underline{ \tt{ \pink{Heat – Stove}}}}}$

When you use a stove, the coil, flame, or cooktop transfers heat energy to the pot or pan that is set on top of it. Then, the heat from the pot or pan is transferred to the food inside.

${ \large{ \underline{ \tt{ \purple{Sound – Headphones}}}}}$

Small speakers in your headphones use electricity and moving magnets to create sound waves. The sound waves that come from the speaker bounce off your eardrums, which your brain interprets as music. Sound waves that you hear, whether they come from another person or a speaker, bounce off objects and move through the air and into your ears. Your brain uses the waves to interpret where a sound is coming from and how loud it is.

${ \large{ \underline{ \tt{ \color{violet}{Gravity – Ballpoint \: Pen}}}}}$

At the tip of a ballpoint pen is a ball that rolls as you push down to write on a piece of paper. There is ink inside the pen that sits on top of the ball. Gravity pulls the ink down towards the paper, and the ball rolls in the ink as you write, taking a controlled amount from inside the pen to the paper surface as it turns. If you were to remove the ball that holds back the ink, gravity would pull all the ink down and onto the paper in a puddle.

${ \large{ \underline{ \tt{ \color{purple}{Inertia – Seat \: Belt}}}}}$

When your body is moving, it takes a more powerful force to cause it to stop moving. In your car, your body is moving as quickly as the car is driving. Your seatbelt, holding you tightly to your seat, is the strong force that prevents your body from continuing to move when you hit the brakes. Without the seatbelt, a sudden stop can send you out of your seat.

${ \large{ \underline{ \tt{ \color{pink}{Electricity – Batteries}}}}}$

Anything with a battery in it stores electrical energy. The car stores electrical energy in its battery that is used to start the engine and to run the electrical components of the car like the radio. The engine uses combustion to create electrical energy that is stored in the battery to be used when it’s needed.
