What compares the amount of energy before and after a conversion is it a aerodynamic shape b energy efficiency or friction?
Energy efficiency compares the amount of energy input to a system with the amount of useful energy output after a conversion. It looks at how much of the initial energy is being utilized effectively. Friction, on the other hand, represents the force that opposes the motion and can lead to energy losses in a system. Aerodynamic shape can impact energy efficiency by reducing friction and improving the overall performance of a system.
What else can I help you with?
Is there friction on a aeroplane nose?
Yes, there is friction acting on the airplane nose as it moves through the air. This friction is known as aerodynamic drag, which is caused by the resistance of the air against the motion of the airplane. Aircraft designers work to minimize this drag to improve fuel efficiency and performance.
What is the relationship between friction and efficiency of a machine?
The relationship between friction and the efficiency of a machine is when friction increases, efficiency decreases, and vice versa. That is why you can never have 100% efficiency, because there is always at least a little friction. They are inversely proportional, meaning, higher friction equals less efficiency.
Why does streamlining reduce air friction?
Streamlining reduces air friction because it shapes an object in a way that allows air to flow smoothly over it, minimizing resistance. This design feature helps to decrease turbulence and drag, ultimately improving the object's aerodynamic efficiency.
How does friction effect effiecency?
Friction reduces efficiency by converting some of the energy input into heat. This results in a loss of energy, making the system less efficient. Minimizing friction through lubrication or using materials with lower friction coefficients can improve efficiency.
How a plane reduces friction?
A plane reduces friction through several means, including the use of aerodynamic shapes to minimize surface contact with the air, smooth surfaces to reduce drag, and lubricants on moving parts to decrease friction. Additionally, landing gears are designed to absorb the impact of landing and reduce friction during takeoff and landing.

Why is the efficiency of a machine is always less than 100 percent?
Some work is lost due to friction. This energy is normally released as heat.

What features will your car have to reduce the forces of friction and drag?
A car will have aerodynamic features to reduce forces of friction and drag. A sleek body style will help do this.
How is friction and mechanical efficiency related?
Friction affects mechanical efficiency by reducing the amount of useful work output compared to the input work. High levels of friction can decrease efficiency by causing energy losses due to heat production and surface wear. By reducing friction through proper lubrication and design, mechanical efficiency can be increased.
