What else can I help you with?
True or false A screw is a simple machine?
True. A screw is a simple machine that converts rotational motion into linear motion. It is typically used to hold objects together or lift loads.
Friction changes the useful work of a machine into mechanical energy true or false?
False. Friction typically reduces the efficiency of a machine by converting some of the input energy into heat, rather than converting it into mechanical energy.
A pulley system always causes the direction of the output force to be the opposite of the input force true or false?
False. A pulley system can change the direction of the force applied, but it does not always result in the output force being in the opposite direction of the input force. The direction of the output force depends on the configuration of the pulleys in the system.
True or False Finding the ratio of input force to output force gives you the mechanical advantage of a machine?
True. The mechanical advantage of a machine is determined by the ratio of output force to input force. A mechanical advantage greater than 1 indicates that the machine amplifies force, making it easier to do work.
Friction is not related to the efficiency of a machine true?
False. Friction can significantly affect the efficiency of a machine by causing energy losses and reducing its overall performance. Minimizing friction through proper lubrication and design can help improve the efficiency of a machine.
True or false A screw is a simple machine?
True. A screw is a simple machine that converts rotational motion into linear motion. It is typically used to hold objects together or lift loads.
What is true of a real machine that enables a person to move a heavy object with little applied force?
I'd go with simple machines. Specifically, probably a pulley (or pulley system).
A computer is a man-made machine true or false?
A computer is a man made device true or false
IS a rowing machine is not a good selection for warm up?
false.
Is a very simple energy conversion device true or false?
False
What are some true or false questions for the time machine?
Here are a few true or false questions related to H.G. Wells' "The Time Machine": True or False: The protagonist in "The Time Machine" is known as the Time Traveler. True or False: The Time Machine allows the Time Traveler to travel both forward and backward in time. True or False: The Eloi are the dominant species in the distant future. True or False: The Morlocks live above ground while the Eloi live underground. These questions can help assess comprehension of the novel's key themes and characters.
A toboggan is used for sliding in the snow true or false?
True!A toboggan is a simple sled that originated in Canada.Read all about toboggan at:toboggan
Kelsey is asked to find the probability of rolling a composite number on a die. She states that this is a simple event. True or false?
False
True Or False. Can horses learn to do simple tricks?
True, if u teach them.
Friction always makes the effiency of a machine less than 100 true or false?
True.
Is a wheel and axle a simple machine consisting of two wheels of different sizes that rotate together?
no its a grooved wheel with a rope running along the groove the above answer is wrong because it is the definition of a pulley. Yes that is true. A wheel and axle is a simple machine consisting of two wheels of different sizes that rotate together.
Is it true a simple machine is one that always gives a mechanical advantage of 2?
Oh, what a lovely question! A simple machine is a device that helps make work easier by either changing the direction or amount of force needed. While some simple machines, like a lever or pulley, can provide a mechanical advantage of 2 or more, not all simple machines will have a fixed mechanical advantage. Each simple machine is unique and can provide different levels of mechanical advantage depending on its design and how it is used. Just like how every brushstroke on a canvas adds to the beauty of a painting, each simple machine plays its own special role in making tasks easier and more efficient.
