Which activity describes work being done on an object?

Answer 1

A person pushing a box across a floor:

· Mass of box = 20 KG, Weight of Box = 196.2

· Distance moved in the direction of the force = 2m

· Work Done = Force X Distance ( in the direction of the force), 196.2 X 2= 392.4 Joules

Answer 2

Work being done on an object is described by the application of a force over a distance, resulting in a change in the object's energy. This can involve lifting an object, pushing it, pulling it, or performing any other action that requires energy transfer to the object.

Answer 3

You need to exert force to the object. The object has to move, if it doesn't move, there's no work done on the object.

Some of the movement of the object must be in the same direction as the force.

The force and the displacement are both vectors. Work is the "dot" product of force and displacement. When movement perpendicular to the force, the force has resulted in no work.

Answer 4

Work is done on an object by a force if the object moves in the direction of the force. Work done is defined as the integral of the force acting over the distance travelled due to that force and is the energy change of the object due to that force. For example, if a force of 2N acting on an object causes it to move 3 metres in the direction of that force, the work done is 2

Answer 5

The equation to calculate the work done is:

Work done (J) = force applied (n) x distance moved of force (m)

Answer 6

Force applied, multiplied by the distance moved in the direction of the force. Any sideways component of movement doesn't count.

Answer 7

the work done by a machine on an object is called work input!
