Discover the impact of a 0.09-N thrust engine on a 480 kg spacecraft's speed during 1 week of maximum power operation. Uncover the assumptions involved in this space physics scenario.

In this video we break down a complex physics problem about a 330-kg piano sliding down a 28° incline while a man resists its motion. We meticulously calculate the force exerted by the man work done by various forces including friction and gravity and the net work done on the piano.

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

Explore the fascinating optical phenomena involving a cat, a converging lens, and the creation of virtual and real images.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.
