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 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.
What else can I help you with?
What is the amount of horizontal force required to start in motion an object sitting on a horizontal surface must be great than what?
The amount of horizontal force required to start in motion an object sitting on a horizontal surface must be greater than the force of static friction acting on the object. This is because the force of static friction opposes the applied force until the object starts moving.
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 are the units of the coefficient of friction?
The coefficient of friction is a unitless value because it represents a ratio of the force required to move an object over a surface to the weight of the object. Since it is a ratio of two forces, it does not have any units associated with 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'.
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
What is significant friction?
Friction that effects the object in motion. insignificant friction is friction that is so small it is negligible.
Force moving object over a distance?
friction
Which has a maximum value kinetic friction or static friction?
The maximum value of static friction is typically greater than the maximum value of kinetic friction. Static friction is the force required to overcome the initial resistance of an object at rest, while kinetic friction is the force required to keep an object in motion.
What is done when a force moves the object throught a distance?
friction
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.
How does the speed of friction change the stopping distance?
The speed of friction affects the stopping distance by influencing the amount of resistance acting against the object in motion. Higher friction speeds can increase the stopping distance as increased speed can cause more energy to be dissipated through friction, slowing down the object over a longer distance. Conversely, lower friction speeds can decrease the stopping distance as less resistance is created, allowing the object to stop more quickly.
How does friction affect the amount of torque required to move an object?
Friction increases the amount of torque required to move an object. This is because friction creates resistance between the object and the surface it is moving on, making it harder to overcome and requiring more torque to initiate and maintain movement.
The measure of force required to move an object?
The measure of force required to move an object is known as the force of friction. Friction is the resistance that occurs when two surfaces come into contact with each other. The force of friction is influenced by factors such as the roughness of the surfaces and the weight of the object.
What is the offset of friction?
The offset of friction refers to the minimum force required to overcome static friction and set an object in motion. It represents the threshold where the object starts moving against the resistive force of friction.
What type of friction required force to start an object moving across a surface?
Static friction is the type of friction that requires force to start an object moving across a surface. Once the object is in motion, kinetic friction takes over to oppose its motion.
How to calculate the work done by friction in a given system?
To calculate the work done by friction in a system, you can use the formula: Work Force of friction x Distance. First, determine the force of friction acting on the object. Then, multiply this force by the distance the object moves against the frictional force. This will give you the work done by friction in the system.
On a flat surface the coefficient of friction is a ratio between and the weight of the object?
The coefficient of friction on a flat surface is a measure of the force required to move one object over another. It is the ratio between the force of friction and the normal force acting on the object, which is determined by the weight of the object pressing on the surface.
