When a force moves objects over a rough horizontal surface at a constant velocity the work done against friction must?
When a force moves objects over a rough horizontal surface at a constant velocity, the work done against friction must be equal to the work done by the applied force to maintain the constant velocity. This is because the force of friction opposes the motion of the object, so the work done by the applied force must overcome the work done by friction to keep the object moving at a constant speed.
What else can I help you with?
If we push a crate at a constant velocity how do we know how much friction acts on the crate compared to our pushing force?
If the crate is moving at a constant velocity, then the force of friction acting on the crate is equal in magnitude and opposite in direction to the force you are applying to push the crate. This means that the force you apply to push the crate is balancing out the force of friction acting against it. By measuring the force you are exerting and observing the constant velocity of the crate, you can infer the magnitude of the friction force.
What is steady friction?
Steady friction refers to the constant resistance that occurs when two surfaces slide against each other at a constant velocity. The friction force remains consistent as long as the relative motion between the surfaces is constant. This type of friction is important in engineering applications where precise control of motion is necessary.
What friction causes a sky divers to change as she falls?
As a skydiver falls, air resistance causes friction against her body, gradually slowing her down. This friction increases as her speed decreases, ultimately leading to a terminal velocity where the forces of gravity and air resistance balance, resulting in a constant falling speed. This friction also helps stabilize the skydiver's position during free fall.
Why a raindrop falling vertically through still air reaches a constant velocity?
The air resistance will increase to the point where it counters the downward acceleration.
How does friction always work to oppose the direction of velocity?
Friction always opposes the direction of velocity because it acts in the opposite direction to the motion of an object. This resistance is caused by the interaction between the surfaces of the object and the surface it is moving against.
A force of 320 N is required to pull a box across the floor at a constant velocity What is the force of friction between the floor and the box?
It's 320 N. Since the friction force is in the direction opposite to the motion, thepulling force and the friction force balance, the net horizontal force on the box iszero, and its speed is therefore constant.

Suppose the force of friction on a sliding object is 25 N The force needed to maintain a constant velocity is?
100 N===========================Answer #2:That depends on the direction of the pulling force.The horizontal component of the pulling force must be 100 N.So the more steeply the rope angles upward, the harder you'dhave to pull on it in order to create a 100N horizontal component.
Does rolling friction always reduce the net force acting on against an objects motion to zero?
The net force will be zero only if the velocity is constant, which means acceleration is zero.
How is an able to maintain a constant speed when friction acts upon it?
An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.
If a car is moving to the left with constant velocity are thera any forces acting on it?
When you say 'moving to the left' I presume you mean with a degree of left turn of the steering wheel rather than the car has turned into a left hand direction and is now moving straight ahead in the new direction. In which case, yes, there is force acting on it. Newton's first law dictates that there must be, otherwise it would not continue to change direction. The force comes from the ground which pushes against the tyres.

A 4kg object is moving across a friction free surface with a constant velocity of 2ms. Which one What horizontal forces is necessary to maintain this motion Explain using Newton's law?
Zero! From Newton's first law, every object continues in its state of rest or uniform motion in a straight line unless a resultant force acts on it to change its state. Thus, if it is required that the object continues in its state of uniform motion in a straight line, no net force is required.
Can an object moving at a constant speed have acceleration?
Acceleration is defined as the change in velocity over a given time period. Velocity is a vector quantity: it includes speed and direction. That being said, you can accelerate an object without changing its speed by simply changing its direction. A body moving along the circumference of a circle its speed may remain a constant, but its velocity will not be a constant since its direction of motion continuously changes, since the velocity changes it has an acceleration.
