1
New cards

Final velocity in constant acceleration motion

v = u + at

2
New cards

Displacement with initial velocity and time

s = ut + 1/2 at²

3
New cards

Equation linking velocity, initial velocity, displacement, and acceleration

v² = u² + 2as

4
New cards

Displacement using average velocity

s = ((u + v)/2) t

5
New cards

Work done with force and displacement at an angle

W = Fd cos θ

6
New cards

Efficiency

Efficiency = useful output / total input

7
New cards

Wave speed, frequency, and wavelength

v = fλ

8
New cards

Total resistance for resistors in series

Rtotal = R₁ + R₂ + …

9
New cards

Total resistance for resistors in parallel

1 / Rtotal = 1 / R₁ + 1 / R₂ + …

10
New cards

Ohm's Law

V = IR

11
New cards

Electric power using current and voltage

P = IV

12
New cards

Electric power using current and resistance

P = I²R

13
New cards

Electric power using voltage and resistance

P = V² / R

14
New cards

Period of circular motion

T = 2πr / V

15
New cards

Radioactive decay

N = N₀ e^(-λt)

16
New cards
