See lessDefine positive work.
Positive work occurs when the force applied to an object causes it to move, and the angle between the force and the displacement is less than 90°.
Positive work occurs when the force applied to an object causes it to move, and the angle between the force and the displacement is less than 90°.
See lessExplain negative work.
Negative work occurs when the application of force causes the point of application to move in the opposite direction to the action of the force or if the displacement has a negative component in the direction of the force.
Negative work occurs when the application of force causes the point of application to move in the opposite direction to the action of the force or if the displacement has a negative component in the direction of the force.
See lessWhat is meant by single work?
Single work occurs when a unit force is applied to an object, and the amount of work done is called unit work if the object moves along the line of action of the force.

See lessWhen is zero work done?
Zero work is done if the force does not cause the object to move or if the point of application of the force moves perpendicular to the direction of the force.
Zero work is done if the force does not cause the object to move or if the point of application of the force moves perpendicular to the direction of the force.

See lessExplain the concept of work.
Work is the displacement of an object due to the application of a force, and it is the product of the force applied and the fraction of the displacement in the direction of the force.
