What is it being When 100 percent of radiation bounces off of an object?
The radiation is being totally reflected.The object is absorbing momentum from the radiation, and is experiencinga force ... being 'pushed' ... in the direction that the radiation was travelingbefore the bounce.I'm not making that up.
What is 90 percent of Earths gravity?
8,9 m/s2 The gravitational attraction on the surface of Venus.
What determines whether or not work is being done?
Work is done when a force is applied to an object and it causes the object to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance the object moved in the direction of the force. If there is no movement or if the force is not in the same direction as the movement, then no work is being done.
Do force exist to object at rest?
There CAN be, as long as the force is being counterd by an equal and opposite force.
What are 5 examples of moving force?
1) A flag being blown by the force of the wind. 2) Iron being pulled towards a magnet. 3) Aget engine propelling an airplane forward. 4) When you write with a pen you exert a force. 5) When you peddle your bike.
What is the force that prevents all machines from being 100 percent efficient?
Friction is the force that prevents all machines from being 100 percent efficient. It produces a resisting force that hinders the machine's complete functioning. Reducing friction will enhance efficiency.
What must take place in order for work to be done?
Energy in some form must be expended, if the machine is 100 percent efficient the work done in Joules will equal the energy input in Joules, but of course machines are never 100 percent efficient, there are always some losses.
What is Force you put into simple machines?
Tension is the force being used in Simple Machines. As well as simple machines may have a little gravity used, tension is the most used.
Why does friction stops machines from not being 100 percent efficient?
Because friction causes a dissipation of heat energy and other kinetic energy. If you use the equation f = ma (Newton's law), where f= force, m= mass; a= acceleration, you can apply this to any machine and factor friction into the mass x acceleration equation. it will always decrease hypothetical force when applied with friction.
What type of simple machines is Pitch fork?
A pitchfork is classified as a type of lever, which is one of the six simple machines. Specifically, it operates as a first-class lever, where the fulcrum is located between the input force (the user's hands) and the load (the material being lifted). The design allows for the efficient transfer of force, making it easier to lift and move hay or other materials.
A measure of the amount a machine multiplies a force is its advantage?
The advantage of a machine is the ratio of the output force to the input force. It determines how much a machine amplifies or magnifies the input force applied to it. Machines with a higher advantage are more efficient at multiplying force.
How is force affect when a simple machine is used?
simple machines are used by being pulled or pushed
What kind of machines are astronauts trained on to simulate being in space?
They use centrifical force machines to duplicate high G-forces. They train underwater to simulate weightlessness.
What do simple machines do to make work easier?
Simple machines make work easier by reducing the amount of force needed to perform tasks or by changing the direction of the applied force. They achieve this by increasing the distance over which the force is applied or by allowing for a more efficient transfer of energy. Examples include levers, pulleys, and inclined planes, which can multiply force or allow for easier movement of heavy objects. By simplifying tasks, simple machines enhance efficiency and reduce effort.
What is a characteristic of simple machines?
A characteristic of simple machines is that they reduce the amount of force needed to perform work by changing the direction or magnitude of that force. They typically consist of few moving parts and include devices such as levers, pulleys, inclined planes, wedges, screws, and gears. Simple machines help make tasks easier and more efficient by allowing users to apply force over a greater distance or to gain mechanical advantage.
Work is made easier when what changes the direction or size of the force needed to do the work?
Work is made easier when machines such as levers, pulleys, wheels, and inclined planes are used to change the direction or magnitude of the force applied, allowing for a more efficient use of energy. These machines help reduce the amount of force needed to perform a task by utilizing principles of mechanical advantage.
What is the force exerted by machines?
torque
