What is the mathematical equation for friction?
An important formula is that friction = (coefficient of friction) x (normal force).
How is friction good and bad?
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
How does friction affect shoes?
Low friction is slippery high friction has good traction. In the sport of Curling (gliding those heavy granite stones on ice towards a bullseye) one shoe has low friction (to slide on the ice) the other has high friction (to propel the player).
How can friction be positive and negative?
Friction can be negative or positive depending on the direction in which your measures are positive.
What is the metric unit for friction?
A friction is a force, so it would be measured in newtons. The coefficient of friction, on the other hand, is a ratio between two forces, so it is dimensionless.
How will an object move that is pulled with the least amount of force?
Neglecting friction, its speed will grow with the least acceleration. Considering friction, it may not move at all.
Why no building can be build without friction?
Friction provides the necessary force to keep the building materials in place and withstand external forces like wind and earthquakes. Without friction, the structure would not be stable and would be prone to collapse. Friction is crucial for ensuring the integrity and safety of the building.

What is actual damping ratio in buildings?
The actual damping ratio in buildings refers to the measure of how quickly the vibrations in a building dissipate over time due to damping mechanisms such as friction, material hysteresis, and energy dissipation systems. It is an important parameter in evaluating the structural response of buildings during earthquakes or other dynamic loads. A higher damping ratio indicates a building with more energy dissipation capacity and better performance under dynamic loads.
Is there friction in a building?
Yes, friction exists in a building when two surfaces come into contact and move against each other. Friction is present between objects like doors, floors, or furniture, which can affect how easily they can be opened, moved, or interacted with in a building.
What is the force that static friction can exert on oa object that is moving 15 kilograms west and 25 newtons is being exerted?
"Static friction" refers to objects that are NOT moving.The amount of friction depends on the so-called "coefficient of friction", which varies depending on the properties of the surfaces that are in contact.
What are the important assumptions made in helical spring experiment?
Some important assumptions made in the helical spring experiment include: linear elasticity, uniform material properties throughout the spring, neglecting the effects of stress concentration at the ends of the spring, neglecting friction between the coils, and assuming that the load is applied along the axis of the spring.
What causes friction that opposes wind?
Obstacles like buildings, trees, and mountains can create friction with the wind, slowing it down and changing its direction. This friction is caused by the wind passing over and around these objects, leading to turbulence and a decrease in wind speed.
Does a rectangular prism slide?
It will depend on the friction. A building brick - approximately a rectangular prism - does not slide easily.
What force is there on free falling body neglecting air friction?
The force acting on a free falling body, neglecting air friction, is solely the force of gravity. This force causes the body to accelerate downward at a rate of 9.8 m/s^2 (or 32 ft/s^2) until it reaches terminal velocity or impacts the ground.
What material was spread on the stones to ease friction?
Lubricants such as oil or water were commonly used in ancient times to reduce friction between stones when constructing buildings. This made it easier to move and place heavy stones into position during construction.
What considerations must engine designers take into account when building a fast-moving vehicle?
Gravity, velocity, and friction?
