Why does someone who carries a 25 kg object a distance of 1 km do no work?
Aquis69
it's all in the definition of work !
the total energy of the object didn't change ... therefore.
You don't have to carry anything anywhere :
hold a rifle out at arms length for 24 hours, some people will swear that there's no work performed ... so use the rifle and make them hold out theirs until they change their mind.

Can you work out the speed of an object by using mass and distance?
An object's speed is (distance it travels) divided by (time to cover the distance). The object's mass doesn't matter at all.
When is work not done on an object?
Work = Force x Distance. so no work is done if there is no force exerted, or if the object does not move.
Is it true that moving an object a shorter distance requires more work than moving an object a greater distance?
false \
What is something done when a force moves an object over a distance?
Work is something that is done when a force moves an object over a distance.
Is it possible to do work on an object that remains the rest?
No. Work = distance x force. If distance is zero, the product is also zero.
What is the product of the force on an object and the distance through which the object is moved?
work
You do on an object when you exert a force on the object that causes the object to move some distance?
You do work

What happens when a force moves an object over a distance?
Work
When is work not done on an object?
Work = Force x Distance. so no work is done if there is no force exerted, or if the object does not move.
When do you do work?
when you exert a force on an object that causes the object to move some distance.
-True or false work is force applied over a distance?
Work = Force times displacement The work done on an object is equal to the Force (push/pull) on the object in Newtons times the distance (in meters) that the object moves. If you push or pull on an object and it does NOT move (zero displacement), then no work is done on the object.
What is something done when a force moves an object a distance?
Work is something that is done when a force moves an object over a distance.
Is it true that moving an object a shorter distance requires more work than moving an object a greater distance?
false \
What is the force to move an object over a distance is?
Work
When work is being done an object is being what?
Moved. Work is defined as a force acting on an object through a distance.
What is something done when a force moves an object over a distance?
Work is something that is done when a force moves an object over a distance.
