Motor vehicle dynamics
CENTRIFUGAL FORCE
Measured in Newtons
FC = mV2/Ry
m expressed in kilograms
V expressed in meters per second
R expressed in meters
KINETIC ENERGY
Measured in joules
EC = 1/2 mV2
m expressed in kilograms
V expressed in meters per second
To convert the result obtained in joules into kilograms,
1 kilogram-meter = 9.80665 joules
MECHANICAL STOPPING DISTANCE
Measured in meters
DA = V2/(9.81 x 2) x µ
V expressed in meters per second
µ expressed in the form of a coefficient
Speed in m/s
To convert a speed expressed in kph into m/s,
simply apply the following formula:
distance in meters/number of seconds per hour
50 kph (31 mph) = m/s ?
50,000/3600
=
13.88 m/s
Reference points
50 kph (31 mph) = 13.88 m/s
90 kph (56 mph) = 25 m/s
110 kph (68 mph) = 30.55 m/s
130 kph (81 mph) = 36.11 m/s
Note
Conversion mph in m / s : One mph = 0.44704 m/s
