the friction force that acts on rolling objects
question
Fluid Friction
answer
opposes the motion of an object through a fluid
question
Inertia
answer
the tendency of an object to resist a change in its motion.
question

question
Buoyancy
answer
the ability of a fluid to exert an upward force on an object placed in it
question
Thrust
answer
a force that is exerted on an object by the acceleration of mass in one direction.
question
Lift
answer
an upward force due to a pressure difference between the top and bottom of a wing
question
Bernoulli Effect
answer
as the speed of a fluid increases, the pressure within the fluid decreases
question
Drag/Air Resistance
answer
acts in the opposite direction of the motion reducing acceleration
