How much force is required to move an object of mass 2kg on a floor with negligible friction to a distance of 5m?
SaqibAhmad
If friction is negligible, then it requires force only to start an object moving, but no force
to 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't
take more force to move an object farther, and it doesn'ttake more force to move a heavier
object, 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 be
when you stop pushing. Also, you can keep up the force through as long or as short a distance
as you want, before you stop pushing.
The product of (force) times (distance) is the energy you put into the object. When you quit
pushing, 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.

Is an object at rest has friction?
An object can be at rest with or without friction. An object floating in outer space can be at rest. An object that is glued to the floor can also be at rest.
What is the amount of horizontal force required to start in motion an object sitting on a horizontal surface must be great than what?
multiply coefficient of static friction by object mass
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 friction prevents an object from moving when a force is applied?
The friction produced that stops an object moving when force is applied is 'static friction'.
What type of friction is the frictional force needed to start on object at rest into motion?
Static
What is significant friction?
Friction that effects the object in motion. insignificant friction is friction that is so small it is negligible.
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.
Force moving object over a distance?
friction
What is done when a force moves the object throught a distance?
friction
What force is required to push an 600N object?
The force required to overcome friction = the coefficient of friction x the reactive force (as in, the force the object exerts on the surface you want to move it over). So, you have to know the coefficient of friction, and simply times it by 600 in this case to know the force required. Oddly, once friction has been overcome, the required force drops slightly to keep it moving.
As your vehicle moves closer to an object you will be required to?
Understand that there is no relationship between the amount of steering required and the distance you are from the object
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
What kind of force is required when an object is moved at rest?
To move an object that is at rest, you must overcome all other forces that are acting on the object, such as friction.
What is the effective of using an inclined plane to lift an object?
A trade-off is obtained between the force required to move an object and the distance through which it is moved. You can use less force over a longer distance so that you can raise an object that you would not be able to lift.The efficiency of a plane depends on the work done in overcoming friction.
Can friction make object yes or no?
Friction can make object no.
What effect does friction have when you try to move a object at rest?
Sticking. An extra force is required to start the motion, above the force required to maintain motion.
What is kinetic friction and static friction?
Friction is the resistance to movement of an object pressing/resting/moving on a surface. It's not intuitively obvious but the standing still friction and moving friction are different. Assume you have a block of wood resting on a tabletop. The amount of force required to make the block begin to move (static friction) is greater than the force required to keep it moving (kinetic friction) after it has begun to move.
