eq from spec Flashcards
1
Q
eq for speed
A
av speed = distance ÷ time
2
Q
eq for acceleration
A
acceleration = change in velocity ÷ time
3
Q
eq for force (mass and acceleration)
A
force = mass x acceleration
4
Q
eq for momentum *
A
momentum = mass x velocity
5
Q
eq for density
A
density = mass ÷ volume
6
Q
eq for work
A
work = force x distance
7
Q
what is energy transferred known as
A
work done
8
Q
eq for kinetic energy
A
kinetic energy = 1/2mass x speed2
9
Q
eq for gpe
A
gpe = mass x g x height
10
Q
eq for weight
A
weight = mass x g
11
Q
eq for pressure
A
pressure = force ÷ area
12
Q
eq for moment
A
moment = force x perp distance from pivot
13
Q
eq for voltage
A
voltage = current x resistance
14
Q
eq for charge
A
charge = current x time
15
Q
eq for electric power
A
power = voltage x current
