00 Equations deck- 3rd Flashcards
1
Q
average speed, distance and time
A
speed = distance ÷ timespeed = distance⁄time
2
Q
force, mass and acceleration
A
force = mass x acceleration
3
Q
acceleration, change in velocity and time taken
A
acceleration = change in velocity ÷ time taken
4
Q
density, mass and volume
A
density = mass ÷ volume
5
Q
weight, mass and gravitational field strength
A
weight = mass x gravitational field strength
6
Q
pressure, force and area
A
pressure = force ÷ area
7
Q
wave speed, frequency and wave length
A
wave speed = frequency x wave length
8
Q
efficiency, useful energy output and total energy input
A
efficiency = useful energy output ÷ total energy input
9
Q
pressure difference, depth, density and g
A
pressure difference = density x g x depth
