What are 2 situations were friction can be helpful?
Friction can be helpful in everyday situations such as when walking to prevent slipping on surfaces. It is also critical for the operation of brakes in vehicles, where friction between brake pads and rotors helps to slow down and stop the vehicle.
When would you want less friction?
There are many applications that would benefit from less friction. Any kind of motion where heat is produced but not intended would benefit from less friction. Some examples: 1. the contact point between the piston and wall in an engine produces less heat and more power with less friction 2. air flow over a car's exterior, over a plane's exterior, over a rockets exterior results in reduced drag (air resistance) with less friction 3. the space shuttle could definitely use less friction with the atmosphere during re-rentry 4. electrical conductors are more efficient as friction decreases 5. if friction were 0, the perpetual motion machine would be possible
How is friction reduced on modern cars?
Friction is reduced on modern cars by using low-friction materials for components like engine parts and tires. Additionally, advancements in lubricants and oils help reduce friction between moving parts. Aerodynamic design also plays a role in reducing drag, which can decrease friction as the car moves through the air.
What 2 things create lots of friction?
Different opinions and beliefs between individuals or groups often lead to friction as they try to assert their perspectives. Poor communication and misunderstandings can create friction in relationships and situations due to confusion or lack of clarity.
The amount of friction between 2 objects?
The amount of friction between two objects depends on their surface roughness, how much force is pushing them together, and the type of materials they are made of. Friction opposes the motion of the objects and can be reduced by using lubricants or by increasing the smoothness of the surfaces in contact.

What are types of friction?
There are 2 types of frictions: 1. Rolling friction 2. Static friction 3. Fluid friction

What are some examples of good friction?
The friction between the tires of a car and the road surface helps the car to grip the road and not skid. The friction between your shoes and the ground helps you to walk or run without slipping. The friction between the strings and frets of a guitar allows you to play different notes by pressing down on the strings.
2 examples of sliding friction?
1) If you push an eraser across a desk, the eraser will move for a short distance and then stop. 2) When you move a heavy dresser by pushing it along the floor.
What is 2 contact forces?
Two examples of contact forces are friction and normal force. Friction occurs when two surfaces are in contact and resist an object's movement, while normal force is the force exerted by a surface to support an object resting on it.
2 types of friction?
There is static friction, and dynamic (also called kinetic) friction.
