Physics in Everyday Life Quiz

A ballpoint pen uses principles of fluid dynamics and friction to facilitate ink flow. When pressure is applied, the ball at the tip rolls, picking up ink from the refill due to gravitational effects.

Roller coasters convert potential energy into kinetic energy as they descend from heights. The initial potential energy from being lifted turns into kinetic energy that propels the coaster down the slopes.

Gravity is crucial as it pulls the coaster down the track, allowing the conversion of stored potential energy into kinetic energy. This force creates the sensation of weightlessness and acceleration during the ride.

<p>Fans operate using fluid dynamics as their rotating blades create a low-pressure zone behind them, causing air to flow and circulate. This movement effectively cools down an area when the fan is turned on.</p> Signup and view all the answers
