What else can I help you with?
True or false work is done only when an object moves in the direction of the applied force?
False. Work is done whenever a force is applied to an object and there is a displacement in the direction of the applied force, whether the object moves in that direction or not. In cases where the object does not move, work is still done as long as there is a force applied over a distance.
How can one determine the work done by friction in a given scenario?
To determine the work done by friction in a scenario, you can calculate the force of friction acting on an object and multiply it by the distance the object moves in the direction of the frictional force. This will give you the work done by friction in that scenario.
When can you say that work is done on an object?
when a force acts to move an object,we say that work was done on the object
When is work not done on an object?
Work is not done on an object when there is no displacement of the object in the direction of the force applied. In other words, if the force and the displacement are perpendicular to each other, no work is done. Additionally, if there is no force acting on an object, no work is being done on it.
Is work done if an object does not move?
No, work is defined as the force applied to an object multiplied by the distance the object moves in the direction of the force. If the object does not move, then work is not done on the object.
Where do you say that work is done an object?
Work is done on an object when a force is applied to the object and the object moves in the direction of the force. The work done is calculated as the product of the force applied and the distance the object moves in the direction of the force.
Is work done when holding object still?
No, work is not done when holding an object still. Work is defined as force applied over a distance, so if the object is not moving, no work is being done.
How does doing work on an object change its energy?
When work is done on an object, energy is transferred to or from the object, changing its energy. If work is done on an object, its energy increases; if work is done by an object, its energy decreases. The change in energy of an object is equal to the work done on it.
Work done against gravity work done against friction?
The work done against gravity is given by the force applied multiplied by the vertical distance lifted. The work done against friction is given by the force applied multiplied by the horizontal distance over which the object moves against the force of friction. Both types of work involve overcoming resistive forces to move an object.
If work done on an object is equal to object's change in kinetic energy this the state of?
If the work done on an object is equal to the object's change in kinetic energy, then the object is in a state of work-energy theorem. This theorem states that the work done on an object is equal to the change in its kinetic energy.
What is the scientific definiton of work?
In physics, work is done when a force applied to an object causes that object to move in the direction of the force. Mathematically, work is calculated as the force applied multiplied by the distance over which the object moves in the direction of that force.
How can work be done?
Work done when force moves an object.
