Does streamlining produce more or less friction?
In general it means that there will be less surface friction on the material. On vehicles this can be done by reducing the impact area at the front and by integrating smooth curves for the air to follow. Surface polishing can also increase airflow and reduce friction.
What effect will the direction of the applied force to a book have on the amount of work being done?
The work being done will be increased if you pick it up instead of dragging it due to the friction.
What can be done to reduce the effect of friction?
Friction on a moving body is dependent on two basic factors and it can be represented as follows Friction force = (Coefficient of friction between the moving surfaces)*( Normal Force between the surfaces) Reducing any or both of the two factors reduce friction. Coefficient of friction can be reduced by: 1. Making the surfaces smoother.(effective for moving bodies in gas,liquid, or on solid/semisolid surfaces) 2. Applying 'Lubricant'. (effective for bodies moving on solid/semisolid surfaces) The normal force can be reduced for bodies in gas and liquids by reducing the press of the medium. (Hence vacuum and high altitude offer less friction than sea level for space crafts). Reduction of the normal force between solid bodies is not practical for machines since this will entirely alter their usefulness. But of course friction couplings, brakes etc use variation of normal force as main criteria for their operation.
Is friction produced when work is done?
No.
What does not reduce the amount of work that has to be done?
A force machine does not reduce the amount of work that has to be done
What is done to reduce friction in ski jumping?

What should be done with non-biodegradable polymers to reduce their effect on the environment?
recycle them

Does a ramp reduce the amount of work being done in science?
No. It reduces the amount of force required, but it does not reduce the total amount of work. In fact, due to friction, it will probably increase the total amount of work.
What are two ways that friction in harmful involving a car?
its harmful to the engine, but without it your car could not move as the tires would just spin. can't have one without the other although things can be done to reduce it in the engine and increase it at the tires.

How do lubricants improve efficiancy?
Efficiency means how much work is done; efficient means less work to accompish the same task. Lubricants reduce friction, thus reducing the work that must be done to accomplish a task.
