IPC Fall Semester Review

Front

What is the formula to calculate force?

Back

F = m * a, where F is force, m is mass, and a is acceleration.

Front

How much force is needed to accelerate a 66 kg skier at 2 m/s²?

Back

132 Newtons.

Front

What is the formula to calculate work?

Back

W = F * d, where W is work, F is force, and d is distance.

Front

How do you calculate power?

Back

P = W/t, where P is power, W is work, and t is time.

Front

What is the relationship between frequency, wavelength, and wave speed?

Back

Wave speed (v) = frequency (f) * wavelength (λ).

Front

A wave has a frequency of 50 Hz and a wavelength of 10 m. What is the speed of the wave?

Back

500 m/s.

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium vibrate parallel to the direction of wave motion.

Front

What is the unit of force?

Back

Newton (N).

Front

What is the unit of work?

Back

Joule (J).

Front

What is the unit of power?

Back

Watt (W).
