Equations Flashcards
1
Q
Voltage
A
Voltage (V) = Current (A) x Resistance (Ω)
V = I x R
2
Q
Charge
A
Charge (C) = Current (A) x Time (s)
Q = I x t
3
Q
Energy transferred
A
Energy transferred (J) = Charge (C) x Voltage (V)
E = Q x V
4
Q
Average velocity
A
Average velocity (m/s) = Distance (m) / Time (s)
v = d / t
5
Q
Acceleration
A
Acceleration (m/s^2) = (Change in velocity) / Time (s)
a = (v - u)* / t
- v = final velocity; u = initial velocity
6
Q
Force
A
Force (N) = Mass (kg) x Accelaration (m/s^2)
F = m x a
7
Q
Weight
A
Weight (N) = Mass (kg) x Gravitational Field Strength (N/kg)
W = m x g
8
Q
Stopping distance
A
Stopping distance (m) = Thinking distance (m) + Braking distance (m)
9
Q
The spring constant
A
The spring constant (N/m) = Force (N) / Extension (m)
k = F / x
10
Q
Frequency
A
Frequency (Hz) = 1 / Period (s)
f = 1 / T
11
Q
Period
A
Period (s) = 1 / Frequency (Hz)
T = 1 / f
