What effect does friction have when you try to move a object at rest?
Friction opposes the motion of an object at rest, making it more difficult to start moving. The force required to overcome static friction and initiate motion is typically higher than the force needed to maintain constant motion.
What kind of energy is produced by a turbine?
A turbine typically produces mechanical energy by converting the flow of a fluid (such as steam, water, or wind) into rotational motion. This rotational motion can then be used to drive a generator to produce electrical energy.
How does the wind cause a turbine to spin?
turbines spin when there is a cause of wind..!!
What is the force required to maintain an object at a constant velocity in free space equal to?
Newton's 1st Law of Motion states that an object will maintain its speed when there is no net force acting on it. The question refers to free space and constant velocity -- the net force has to be zero. =========================
Why it is difficult to start motion than to maintain it?
To start with we have to change the speed right from zero to some value. So force is required and with that force work is to be performed. Hence energy is needed. After attaining that speed thereafter we need energy just to compensate the loss due to friction. Hence maintenance of the uniform motion is easier than attaining that uniform speed right from rest. If v is the speed attained for a mass m, then 1/2 m v^2 is the energy required. There after just frictional force x displacement is energy required to maintain the motion.

Is it true that a turbine turns kinetic energy to electrical energy?
No. A turbine turns linear motion of a working fluid (which can be a liquid or gas) into rotational motion. No electricity need be involved.You can hook a turbine to a generator and use the rotational motion produced by the turbine to make electricity. But the turbine itself does not do this.
What is the source for mechanical motion supplied to a generator called?
The source for mechanical motion supplied to a generator is called a prime mover. This prime mover can be in the form of a steam turbine, gas turbine, water turbine, wind turbine, or internal combustion engine, which converts mechanical energy into electrical energy through the generator.
What is the minimum amount of knee flexion required to effectively ride a bike?
The minimum amount of knee flexion required to effectively ride a bike is typically around 25-30 degrees. This allows for proper pedaling motion and power generation while maintaining comfort and efficiency.
How heat energy can be converted into mechanical?
One common method is for the heat to be used to generate steam in a turbine. The steam is allowed to escape from the turbine in specific directions. The force of the steam leaving in one direction causes an equal force which will move the turbine in the opposite direction. The rotational motion of the turbine is [rotational] mechanical energy. This energy can be used to drive machines which can convert the rotational action into linear action - if required.
What is idle speed for Ohio boating laws?
It is essentially the same as headway speed, or "no wake" speed. The minimum speed necessary to maintain forward motion and steering control.

How does the wind cause a turbine to spin?
turbines spin when there is a cause of wind..!!
What is a wind turnbind?
A wind turbine is a form of electric generation. On top of a tall pole there is a turbine (fan thing) and the wind spins it around. The turbine is connected to a motor which generates an electromagnetic flow from the motion.
What is meant by axial displacement in steam turbine?
Axial displacement is the motion along the shaft of the turbine caused by the force exerted by the steam or by the thermal expansion of the shaft and casing.
Is force required for displacement of an object?
No. Force is required for accelerated motion, but not for uniform motion.
How does a turbine pump electrons around a circuit?
A turbine is often used to spin the rotor of a generator. The generator converts this kinetic (energy of motion) energy into electric energy. A turbine does not directly push electrons around.
