'Acceleration' means ANY change in speed or direction
of motion.
A). Acceleration. The satellite is in a curved orbit, so
its direction is constantly changing.
B). Acceleration. The person is on a curved track, so
his direction is changing.
C). Acceleration. The car is following a curve, so
its direction is changing.
D). No acceleration. Straight, at constant speed.
No change of speed or direction.
The value of constant in terms of Force, k, A, V and ρ is x = ln (F /kAρV ).
<h3>What is opposing force?</h3>
The force which tends to oppose motion of fluid in forward direction like shear stress in liquids and friction force in solids
A body moving through the air at speed V, experiences the retarding force.
Force = kAρVˣ
where A is the surface area, ρ is the density of air and k is the numerical constant.
Taking natural logarithm both sides,
ln F = ln (kAρVˣ)
ln F = x ln (kAρV)
x = ln F / ln (kAρV)
x= ln (F /kAρV )
x= ln F - ln (kAρV)
Thus, the value of constant is deduced in terms of Force , k, A, V and ρ.
