What kind of friction must you overcome to get an object to start moving?
Static Friction
What do you must do to overcome to start an object moving that is at rest?
You must overcome static friction.
What force do you have to overcome to start an object moving?
Sticky friction.
What force must you overcome to start an object moving?
Friction. Specifically, static friction. After the object begins to move, it will still be necessary to overcome rolling or sliding friction to keep it in motion.
Of the two forms of friction you studied friction is the one that must be overcome in order to start something moving?
static
Is kinetic friction the one that must be overcome in order to start something moving?
static
When do steams deposit sediments?
When gravity and friction overcome the ability of the moving water to move them.
Static friction is the force that must be overcome in order to start something moving?
that is true
Give an example of fluid friction?
A plane moving through air. Air is causing friction, A boat moving through water .Water causes friction.
It is generally easier to push an object once it is moving than when you are getting it started this is because?
When an object is at rest, static friction is acting on it. But once it is overcome, the object moves comparatively easier due to the fact that the moving objects face kinetic friction which is always less than static friction. +++ It's not the friction you have to overcome, but its inertia, proportional to its mass. Think of an astronaut servicing something on the outside of the International Space Station. There is no friction acting on him, he is weightless and both he and spaceship are moving together through space at great speed; , but he still has mass so to move himself along the hull he still needs to push against it to overcome his inertia.
Why did you pull a sneaker that wasn't moving to test starting friction?
Why do you pull the sneaker at a slow speed for stopping friction?
Explain why objects moving in fluids must have special shapes?
When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.
