If you have eliminated all resistance then the initial force will be enough.

How does inertia work?
It is exactly the same as momentum and covered by Newton's first law of motion. Inertia is a way of expressing the force required to get an object to move from rest, or the force required to change the velocity or direction of an object in motion. Anything that has mass will have inertia - a "resistance to move or change velocity or direction of motion".
What is the principle of inertia?
The principle of inertia No force is required to maintain motion with constant velocity in a straight line, and absolute motion does not cause any observable physical effects. In layman's terms: An object that is moving will keep moving until something stops it.
In what year did congress pass the selective service act which required all male citizens to register for military draft upon turning eighteen?
Probably during WWII; it was constant because of the cold war...and didn't end until the Vietnam War.
How much did ancient Egyptian metal workers get paid?
People didn't get paid like we do today. They got food, some got housing while working on the pyramids. Workers on the pyramids were a combination of slave labor and required work for the population. Copper tools were used and this required constant reworking and making the tools since copper is a soft metal and doesn't last long.
What was the major cause of shayss rebellion?
Taxes required of poor farmers
What are the conditions required to swing continuously in air?
absence of friction...no air resistance
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No, the force required to keep a rocket ship moving at a constant velocity in deep space is not equal to the ship's weight. In deep space, where there is no significant gravitational force acting on the ship, the force required to maintain its velocity is equal to the force needed to overcome any resistance, such as air resistance or friction. Weight is a measure of the gravitational force acting on an object due to the planet's mass, and it is not directly related to the force needed to maintain velocity in deep space.
What is the formula for horsepower needed to carry 6000 pounds at 55 mph?
I assume you want to transport this on a train, or truck, or something like that. There is no simple relationship. Basically, the only power required to transport something at constant speed is the power required to overcome friction (otherwise, with no friction, zero power would be required to maintain the speed.) However, friction on the road or rails can vary; air resistance can vary depending on the shape of the train or truck, and even on the wind.
How much power required to propel a ship while resistance is neglected?
The power to propel a ship is dependent on a number of things besides resistance. You must consider the size of the ship, its weight, and its passenger's weight before you can determine the power required to move it.
The lower the value of the coefficient of friction what is the resistance to sliding?
The lower the coefficient of friction, the lower the resistance to sliding between two surfaces. A lower coefficient of friction means that it is easier for one surface to slide past the other with less force or effort required.
What force is required to push an 600N object?
If the object is at rest, a force greater than 600N would be required to overcome static friction and start its motion. Once in motion, a force equal to 600N would be needed to keep the object moving at a constant velocity on a level surface, assuming there is no other resistance.
How do you find magnitude of force by using a constant speed?
If an object is moving at a constant speed, the net force acting on it is zero according to Newton’s first law of motion. This means that the magnitude of the force required to maintain that constant speed is equal in size but opposite in direction to any external forces acting on the object, such as friction or air resistance.
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?
The force of friction between the floor and the box is 320 N. This is because the force required to pull the box at a constant velocity is equal in magnitude to the force of friction acting against the motion.
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 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.
Where the friction is not required in sports?
Friction is not required in sports like swimming and diving because it is beneficial for athletes to move through water with minimum resistance. Additionally, in sports like gymnastics and figure skating, reduced friction allows for smoother and more controlled movements during routines.
How are static friction sliding friction and rolling friction different?
Static friction occurs when an object is at rest and resists the initial force required to set it in motion, while sliding friction is the resistance encountered when an object slides over a surface. Rolling friction is the resistance experienced when an object rolls over a surface, which is typically less than sliding friction due to the reduced contact area.
