Mother pushes a baby stroller 50 meters by applying 10 newtons of force. How much work was done?
A mother pushes a baby stroller 50 meters by applying 10 newtons of force. How much work was done?
A worker applies a 200-n force to a create that he pushes 10m how much work was done?
According to the formula, Work done = Force . Displacement So, 200(10) 2000 joules. Hence, the work done by the person will be 2000 joules.
A rock moves in a straight path in space with a constant speed.is there any force acting on the rock.is there any work done when the rock moves?
There is no force acting and therefore no work done.
How much work is done on a 50 newton rock that you lift 10 meter?
500 Joule.
You exert a force of 75 newtons on a rock. You push and you push, but you can’t budge it. You are exhausted! How much work did you perform?
Unfortunately, 0. The rock has 0 displacement, so despite force being exerted no work was done (at least in physics terms).
What is the science meaning of work?
In physics, "work" is the product of a force upon an object. If a man pushes on a rock and it moves, then work has been done. If the rock does not move, then no work has occurred even though force has been exerted.

There is no force acting and therefore no work done.
How can strain energy do work?
It can do alot of work. Eg. When you use a cannon launcher or slingshots. We pull it using the rubber and the stored energy pushes the cannon ball or rock and attacks.
Is physical work requiring energy being done if a person pushes on a locked door?
Yes because work is using energy to move something. Anytime we push-pull, work (energy) is used.
Can work be done in space?
No, because a force is not being exerted either on the rock or by the rock. It has momentum in a friction free enviroment.
Is work done if a person pushes against a car and it doesn't move?
yes didnt you pay attention in physics? Actually this answer is wrong. You only do work if the car moves according to the laws of chemistry.
