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 a force that maintains motion called?
A force that maintains motion is called inertia. This is the same as to what is normally referred to as momentum.
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.
How can you turn water energy into electricity?
The energy produced by water in motion is passed through a fan or turbine. A generator attached to the fan or turbine spins with it and produces electricity.
What is the force that maintain motion?
There is no force that maintains motion by itself. Motion is maintained by Newton's Law, that objects in motion tend to stay in motion. Forces can act to stop the motion, such as the force from friction, in which case some other force, such as the force provided by a car's engine, is what keeps the car from slowing down and stopping. But, in the absence of forces acting against motion, such as friction, an object will remain in motion with no forces acting on it.

Sticking. An extra force is required to start the motion, above the force required to maintain 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 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 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.
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.
Name one way ocean waves can be helpful?
i think for tidal power (Rotech Tidal turbine), inwitch the motion of the waves rotate the turbine. the turbine is connected to a generator witch generates power.
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.
Forces that maintain motion?
momentum
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.
