What else can I help you with?
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.
What is the transfer of energy that causes an object to move in the direction of the force called?
The transfer of energy that causes an object to move in the direction of the force is called work. Work is defined as the product of the force applied to an object and the distance over which the force is applied in the direction of the force.
Explain how negative work on a system occurs?
Negative work on a system occurs when the force applied to the object is opposite to the direction of motion, resulting in a reduction in the system's energy. This can happen, for example, when a force is applied to slow down an object's movement, causing it to lose kinetic energy.
What force allows work to be done?
Any force can produce work if it causes displacement. If displacement is in opposite direction of force, work done will be negative and if displacement is in direction of force work done will be positive. If there is no displacement, work done is zero. Eg: Gravitational force pulls you down towards earth, in pulling you down it does work on you which gets stored in form of potential energy. Energy for A+
What happens when a force moves?
When a force acts on an object and moves it, work is done. The work done is equal to the force applied multiplied by the distance moved in the direction of the force. This can result in the object gaining kinetic energy or performing mechanical work.
According to the scientific definition for work what must happen in order for work to be accomplished?
In order for work to be accomplished, there must be a force applied to an object and the object must move in the direction of the force. Work is the product of the force applied to an object and the distance over which the force is applied.
Who For work to happen the only requirements for force to be applied to an object and the object must feel pressure yes or no?
No. Force must be applied and the point of application of the force must move. Work = force x distance.
What 2 things need to occur for work to happen?
For work to happen, there needs to be a force applied to an object and the object must move in the direction of the force. Work is calculated as the product of force and distance moved in the direction of the force.
If a force of 100 newtons was exerted on an object and no work was done the object must have?
If no work was done, the object must not have moved in the direction of the force. This could happen if the force was applied perpendicular to the object's motion or if the object remained stationary.
According to the scientific definition of work what must happen in order for work to be accomplished?
In order for work to be accomplished according to the scientific definition, a force must be applied to an object, causing it to move in the direction of the force. Work is done when this force causes the object to be displaced.
What must happen to an object if a force does not work on it?
If a force does not work on an object, the object will either remain at rest or continue moving at a constant velocity in a straight line, according to Newton's first law of motion.
In order to do work on an object the object must what as a result of your force?
In order to do work on an object, the object must move in the direction of the force applied. If the object does not move, no work is being done on the object.
What must be true when work is done?
When work is done, there must be a force acting on an object, and the object must move in the direction of the force. The amount of work done is calculated by multiplying the force applied by the distance the object moves in the direction of the force.
What is required for a force to do work on an object?
in the same direction as the object's motion.
What conditions must exist in order for a force to do work on an object?
The force must couple to the object. The point of application of the force must be able to move in the direction of the force.
What must occur for work to be done?
For work to be done, a force must be applied to an object, causing it to move in the direction of the force. Work is defined as force acting over a distance, so the object must be displaced by the force applied to it in order for work to be done.
What must occur in order for work to be done?
"Work is done on an object if two things happen: (1) the object moves as a force is applied and (2) the direction of the object's motion is the same as the direction of the force.".SOURCES:Dumas, Leila, and William G.
