∙ 14y agoThough its primary purpose is to stop water from going into a swimmer's ears, (and keeps hair fairly dry), it can help a swimmer to move faster. The cap has a tiny bit less friction with the water than hair does, and this can have a measurable effect on speed, especially at the competitive level.

∙ 11y agoyes, hair is probably the main reason you get drag. By wearing a swim cap, it will decrease the chance of getting frictional drag and that will increase your speed in the water.. Shaving body would also help increase your speed (:

∙ 9y agoSwimming with a cap allows you to swim faster...but only but only slightly.
This is because without a cap your hair creates the slightest bit of drag and also soaks up the water makes you heavier

∙ 12y agoSwimmers reduce drag often by shaving, wearing swim caps, and often wearing elite swim suits that are extremly tight so there are no bumps, all of these result in reducing drag.

to increase the speed & reduce resistence of the boat
Either to increase speed and reduce torque or to decrease speed and increase torque while conserving mechanical energy.
Generally it will reduce both speed and range.
Reduce the size of the pulley on the motor
first do you reduce the voltage level or increase the load factor
You can change the chain sprockets of most motorcycles to get a higher top speed. Reduce the rear sprocket numerically, and/or increase the front sprocket numerically. A higher profile tire will also increase top speed slightly.
To increase rocket speed, you can add more propellant to increase thrust, reduce the rocket's mass by shedding unnecessary weight, or improve aerodynamics to minimize drag. Additionally, optimizing the rocket's trajectory and using efficient engine designs can also help increase speed.
That shuttle run is hard to reduce in time unless you increase in speed.
A river's speed may increase due to factors such as the gradient or slope of the land, the volume of water flowing in the river, and the presence of obstacles that reduce friction. Additionally, changes in the river's width or depth can influence its speed as well.
It usually( depending on brand) modifies the amount of fluid to the rack to increase/reduce the assistance based on the speed of the wheel.
Flaps are used on aircraft to increase the wing area of the plane and therefore increase lift and reduce speed.
Your vehicle will not grip the road as under normal conditions. You must reduce the speed, increase the safety distance from other vehicles and reduce the torque on your wheels by driving in the highest gear possible for your speed.
