What are some common products that take advantage of knowing the coefficient of friction? Why is friction not useful for car engines? What are the different laws of friction? Why does air friction affect a car's gas mileage? What is surface tension and what does tension in surface mean?

Steve4Physics said: You are being asked to find the work done by L→, not the work done by W→+B→. Doc Al said: What's lifting the stone? That's the force that's doing the work. L=mg-rhoVg (taking g=10) W=Ld W=250 J If it was in air then the appli...
Usability Testing: Watch users interact with prototypes or early versions of your product. Notice where they get stuck or seem confused. Observing their behavior can highlight friction points that need addressing, and it often uncovers issues you wouldn’t have anticipated. ...
Creating a great on-site survey requires following some set of dos and don’ts. They are not set in stone, but they can helpavoid survey mistakesthat may affect data quality and response rates. 1. Pay Close Attention to the Context ...
Does the normal force affect the coefficient of kinetic friction? If an object is at rest, can you conclude that there are no forces acting on it? A block is at rest on a place inclined at angle \theta. The forces on it are the gravitational, normal and friction forces, shown below....
What is another way to say "the force due to gravity"? a. weight b. air resistance c. friction d. applied force e. normal force How does the mass of an object affect the outcome when an unbalanced force acts on it? What is constant acceleration?
