what is work done?
what is force?
koi thanks dedo plz
Answers
Answer:
answer 1: Work is done when energy is transferred from one store to another. Work is also done when a force causes an object to move. When work is done against frictional forces acting on an object, the object's temperature increases.
answer 2: In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
Answer:
please mark me brainlist I will thanks your all ans.
Explanation:
1st Ans.
Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. If the force is constant, work may be computed by multiplying the length of the path by the component of the force
acting along the path.
2nd Ans.
Any action which causes pull,hit or push on a body is called force.
