Why do jet streams flow parallel to isobars?
Because jet streams are above the friction layer, they have a negligible effect. The wind is balanced by the Coriolis effect and the pressure gradient so that the winds flow parallel to isobars.
What is your sentence for effect?
The effect was negligible.
What is the force that always opposes motion?
The first law of Newton suggests that an object will keep moving until an equal or opposite force reacts onto it changing its speed or direction of momentum. A force that would ALWAYS oppose motion would be friction because we are surrounded by air and anything in motion will always have air molecules bumping against it causing it to slow down. Even the road causes friction on the wheels of a car; pavement causes friction on your shoes and so on. The only place friction can be negligible (not in all cases) is in a vacuum where no air is present and that is only if the object is not rubbing against anything else. i.e. the outer space So the answer to your question is pretty vague unless you specify WHERE this object would be. Depending on the surroundings, there is almost always something that opposes motion even if it doesn't seem like there is any friction present. i.e. hockey puck on ice may seem like it has no friction but that is not true!
What are 5 types of friction?
1. Static2. Sliding3. Rolling4. Air5. Fluid
As soon as an object starts moving what replaces static friction?
Kinetic Friction replaces Static Friction when an object is in motion.
Which surface gives the least friction?
Plane surface with negligible friction.
What is significant friction?
Friction that effects the object in motion. insignificant friction is friction that is so small it is negligible.
Does a rollercaoster have greater kinetic energy if it fall from 25 meters instead of 10 meters?
yes as long as friction is negligible.
How do object charged by friction?
how objects become charged by friction
When you rub your hands together they become warm what is this due to?
Friction
How much force is required to move an object of mass 2kg on a floor with negligible friction to a distance of 5m?
If friction is negligible, then it requires force only to start an object moving, but no forceto keep it moving. You could barely touch it, so that it just begins to creep imperceptibly,and then back off completely ... if friction is negligible, the object keeps going. It doesn'ttake more force to move an object farther, and it doesn'ttake more force to move a heavierobject, if friction is negligible.Where friction is negligible, force causes an object to accelerate. When the force is removed,the object continues moving at a constant speed.Where friction is negligible, you can push on the object as hard or as lightly as you want ...the harder you push, the greater its acceleration will be, and the greater the speed will bewhen you stop pushing. Also, you can keep up the force through as long or as short a distanceas you want, before you stop pushing.The product of (force) times (distance) is the energy you put into the object. When you quitpushing, all of that energy you gave the object will show up as the object's kinetic energy.It will be equal to (1/2 x the object's mass) times (its speed).The quantities are all up to you.
What are four ways to increase the acceleration of an object?
Apply a larger force. Make the object less massive. Decrease air resistance acting on the object. Decrease the coefficients of friction by using a 'smooth' surface, where friction is negligible.
Sitting on a chair is an example of friction?
without friction most things become impossible.
What happens to friction when objects become wet?
you die
Why does a nail become hot when hammered into a piece of wood?
Friction
How do material become charged?
by rubbing(or friction) by contact by induction
How can you determine charge for an unknown material?
One can determine the charge for an unknown material by using negligible friction. One will then be able to compare reactions between different charges that are brought near the unknown material.
