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
