v =
d/t
d=
v x t
t =
d / v
distance is axis =
y
time is axis
x
time and distance increasing steadily together
constant speed- straight upwards sloping line
time increasing, distance not changing
stationary - straight horizontal line
steeper line (DT Graph)
higher constant speed
line curves vertically (DTG)
acceleration
line curves down (DTG
deceleration
a =
v / t
v =
final speed - initial speed
time increasing constantly with speed
constant acceleration
time increasing, speed doesn’t change
constant speed, straight horizontal line
steeper line (STG)
greater acceleration
downwards sloping line (STG)
constant deceleration
dsitance travelled STG rectangle
b x h
distance travelled STG triangle
1/2 x b x h
Force =
ma
a =
f / m
m =
F / a
Pressure
F / A
pressure units
