What else can I help you with?
Why are cars designed with smooth surfaces?
to reduce air resistance
What are surfaces with very little friction?
Surfaces with very little friction include ice, polished metal surfaces, and Teflon-coated surfaces. These surfaces reduce friction because they have smooth textures or surface coatings that allow objects to slide over them with minimal resistance.
What is air resistance reduced by?
Air resistance is reduced by the streamlined of shapes. Because for eg. if you have two cars both weighing the same but their shape in the front are different the one with the sharper point will go faster and reduce fuel.
What is the most likely reason cars are designed with smooth surfaces?
reduce air resistance
What can reduce the effect of air resistance?
Reducing the speed of the object or increasing its surface area can help reduce the effect of air resistance. Streamlined shapes and smooth surfaces can also minimize air resistance.
What objects are streamlined to reduce friction by air resistance?
like deflectors on lorries
Which force will decrease if the surface of the ramp is made smoother?
Friction is the force that will decrease if the surface of the ramp is made smoother. Smooth surfaces reduce friction by allowing objects to slide more easily with less resistance.
What surface causes the least friction?
Teflon.
What are 2 ways to reduce the effects of fricton?
Using lubricants such as oil or grease to reduce friction between surfaces. Using smooth surfaces or materials with low friction coefficients to minimize resistance between moving parts.
How does resistance effect the shape of a rocket?
Resistance can affect the shape of a rocket by increasing drag, which can slow down the rocket and reduce its efficiency in reaching its intended destination. To minimize resistance, rockets are typically streamlined with pointed fronts and smooth surfaces to reduce drag and improve aerodynamics.
What can be done to minimize the effect of friction?
To minimize the effect of friction, you can use lubricants between surfaces, choose materials with lower friction coefficients, reduce the contact area between surfaces, and ensure proper surface smoothness to reduce frictional resistance.
What are the 3 ways of decreasing the friction?
Decreasing friction:- add a lubricant (like oil in a door hinge)- rolling objects (e.g. rollerblades)- streamlining (like making an aircraft a special shape to reduce wind resistance)Source(s):I have a good memory and listen in school
