The frictional force caused by these collisions is known as drag, which slows the glider down. The amount of drag is proportional to the airspeed of the hang glider: The faster the glider moves, the more drag it creates (see How Gliders Work for details). How a pilot maneuvers a hang ...
In summary, to determine the instant a block overcomes static friction, you must analyze the forces acting on the block, particularly the applied force and the static frictional force. Calculate the maximum static friction using the coefficient of static friction and the normal force....
Learn what a non-conservative force is. Understand the differences between conservative and nonconservative forces and find non-conservative force examples. Related to this Question Why doesn't friction depend on surface area? Explain. Does friction depend on the area of contact? Explain?
Often, this quantity is expressed as ideal mechanical advantage, or IMA, which is the mechanical advantage the machine would enjoy if not frictional forces were present. Lever Basics A simple lever is a solid rod of some sort that is free to pivot about a fixed point called a f...
A synchro's purpose is to allow the collar and the gear to make frictional contact before the dog teeth make contact. This lets the collar and the gear synchronize their speeds before the teeth need to engage, like this image. HowStuffWorks The cone on the blue gear fits into the cone-...
The great thing about modeling physics is this: if you model the forces correctly, you’ll get objects that behave realistically. You don’t need to think about directly modeling complicated interactions. If you have a ball that you want to drop from the sky, but you also want it to reac...
Yet, such accelerations might be unavoidable: To fly at hypersonic speeds, planes might rely on specializations that render them unwieldy pigs at lower velocities; thus, they might require rocket boosters -- and the G-forces they entail -- to reach flight altitude and speed [sources: NASA; ...
How do you find the value of mu in a physics problem? To find the value of mu, you need to know the normal force acting between the two surfaces and the frictional force acting on the object. The coefficient of friction can then be calculated by dividing the frictional force by...
Three separate forces act on a plate fixed about an axis through point O that is perpendicular to the plate as shown in the figure below. The forces are F1 = 7.00 N, F2 = 5.00 N, and F3 = 5.00 N. Find the torque produced by F1, F2, and F3 about an axis ...
Why doesn't the normal force affect kinetic frictional force? How does increasing the speed of an object change its momentum? How to calculate change in momentum How are impulse and momentum related? What does friction mean in physics? What does friction depend on? What is the difference betwe...
