Drag is a type of friction will cause an extra exertion of energy while moving in the water. Swimmers shave all the hair from their bodies, and use swim caps to prevent their hair from causing drag to gain more time.

What is the force that slows a parachutte?
Drag - a form of friction and lift.
What forces act when you lift weights?
force of friction in air and force of gravity downward.
Does a person have force friction and gravitation?
Yes. -- Force when you lift something. -- Friction on the soles of your shoes when you walk. -- Gravitation all the time.
Why does the input force have to be greater than the force needed to lift the bale?
Friction increases the effect of the input force
Why does the input have to be greater than the force needed to lift the bale?
Friction increases the effect of the input force
What is the force that opposes objects through water?
Friction with the water.
How many force are there?
3300 salamander
What is the name of the force that slows a boat down?
Generally, friction will slow kinetic motion in water and air alike.Gravity will always tend to pull things down, thus slowing upward motion.Generally, friction will slow kinetic motion in water and air alike.fluid friction
Is more force is usually required to pull an object than to lift it?
Heavier (more massive) objects require more force to move than lighter objects. The formula is F = ma (force is equal to mass times acceleration). The same force applied to a more massive object will provide less acceleration (motion).
If the coefficient of static friction is 0.3 how much more force is needed to lift the object than start it sliding?
for lifting the object there is no role of friction,but of air friction.since no info,. is given about it so air friction = 0.thereby for lifting we have mg = mass * 9.8 (the wight of the object). and for sliding we have 0.3*mg . therefore 0.7mg of more force is required to lift it.
What energy changes take place when you use a boat?
Usually the water force friction takes place of the boat it pushes the gravitational force and the friction force takes place
What is an attractive force between different substances such as water and glass?
friction
