FLASHCARD QUESTION

Front

How do you calculate frequency from the number of spins and time?

Back

Frequency (Hz) = Number of spins / Time (s). For example, a ceiling fan spins 600 times in 20 seconds, so frequency = 600 / 20 = 30 Hz.

How do you calculate the reindeerpower produced by Rudolph's jump?

Back

To find the reindeerpower, use the formula: (mass * gravity * height) / time, then divide by 746.

What is the formula for gravitational potential energy?

Back

Gravitational potential energy (PE) = mass (m) * gravity (g) * height (h).
