BC Science Physics 11

General Physics 11 flashcards covering Wave Motion, Kinematics, Dynamics, and Energy based on the BC Science Physics 11 curriculum.

What is the relationship between period (T) and frequency (f) in wave motion?

T = 1/f

How is the index of refraction (n) defined in terms of the speed of light?

n = c/v, where c is the speed of light in a vacuum and v is the speed in the medium.

What formula represents Snell's Law for refraction?

n1sin(θ1) = n2sin(θ2)

What is the formula for average velocity (v) in kinematics?

v = Δd/Δt

How is acceleration (a) defined mathematically?

a = Δv/Δt

State the kinematic equation that relates final velocity, initial velocity, acceleration, and time.

vf = vi + at

What kinematic formula relates displacement to initial velocity, time, and acceleration?

d = v_it + 1/2at^2

What is Newton's Second Law of Motion?

F_net = ma

How is momentum (p) calculated?

p = mv

What is the formula for gravitational potential energy (Ep)?

Ep = mgh

What formula defines kinetic energy (Ek)?

Ek = 1/2*mv^2

How is mechanical work (W) calculated when a force constant?

W = Fd

What is the formula for power (P)?

P = W/Δt or P = ΔE/Δt

What is Einstein's famous mass-energy equivalence formula?

E = mc^2

What formula describes Hooke's Law for spring force?

F_s = kΔx
