physical science flash cards for year 10
| Question | Answer |
|---|---|
| Net force? | F(Net) = ma |
| Kinetic Energy? | KE = 1/2mv(*2) |
| elastic potential energy | EPE = 1/2kx(*2) |
| acceliration | a = △v/t = v-u/t |
| gravitational potential engery | GPE = mgh |
| momentum | p = mv |
| velocity | v = △s/t = s(initial) - s(final)/t |
| Avogadro's constant | Na = 6.022x10(*23) |
| Gravity Acceleration | g = 9.8 ms (*-2) |
| number of moles (using molecules) | n = N/Na |
| Number of moles (using mass) | n = m/Mr |
| Resistance Total (multiple resistance) | R(t) = R1 + R2 + R3... |
| Current Total | I(t) = I1 + I2 + I3... |
| Voltage Total | V(t) = V1 + V2 +V3... |
| Resistance (using current and voltage) (rearrange depending on question and what you need to find) | R = V/I |
| Resistance Total (Parallel circuits) | 1/R(t) = 1/R1 + 1/R2 +1/R3... |
| Heat released or absorbed | △H = H(products) - H(reactants) |
| How much heat is need to make the change in temp | Q = mc△T = mc(T(final) - T(initial)) |
| V | Volts |
| I | Current (Amps) |
| R | Resistance (Ohms) |
| m | Mass |
| v | Velocity |
| F | Force |
| Gravity Force | F(g) = mg |
| g | Gravity acceliration (9.8ms(*-2)) |
| k | constant |
| x | Meters (extended/compressed) |
| h | height |
| a | acceliration |
| t | Time |
| c | heat capacity (water = 4.18Jg(*-1) |
