(V) Suggest three ways to reduce and three ways to use the friction.
Answers
Answer:
Methods for decreasing friction:
Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
Lubrication is another way to make a surface smoother. ...
Make the object more streamlined. ...
Reduce the forces acting on the surfaces. ...
Reduce the contact between the surfaces.
Answer:
ways to reduce friction
1.For objects that move in fluids such as boats, planes, cars, etc, the shape of their body is streamlined in order to reduce the friction between the body of the objects as the fluid.
2.By polishing the surface, as polishing makes the surface smooth and friction can be reduced.
3.Using lubricants such as oil or grease can reduce the friction between the surfaces.
4.When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings
ways to use friction
Friction is responsible for many types of motion
1.It helps us walk on the ground
2.Brakes in a car make use of friction to stop the car
3.Asteroids are burnt in the atmosphere before reaching Earth due to friction.
4.It helps in the generation of heat when we rub our hands
hope so this helps you...
