Equations Flashcards
average speed, distance travelled and time taken
speed = distance travelled ÷ time taken
speed = distance travelled ⁄ time taken
force, mass and acceleration
force = mass x acceleration
F = ma
acceleration, change in velocity and time taken
acceleration = change in velocity ÷ time taken
a = (v-u) / t
momentum, mass and velocity
momentum = mass x velocity
p=mv
density, mass and volume
density = mass ÷ volume
