Work is force x distance = 700 x 4 = 2800 Joules
joules is energy, not a force
The idea here is to multiply the force by the distance.
Exactly 2.6 joules for each meter that you keep pushing it.If the book doesn't move, then there's no work.
Thrust is the force that pushes something (typically a rocket) forward. The term force is more general; there are many kinds of force.

Joules is the unit of work being done. A 200 Ib man exerts 882 Newtons is not getting any work done. If 882 Newtons, which is the force, was multiplied by 0 movement, then the 200 Ib man is exerting 0 joules.
One foot-pound of force equates to about 1.355818 joules.
Depends on how much force is placed into a punch.
The formula for work done against gravity is straightforward multiplication.W= F x D (force times distance) and therefore W = m x g x dThe values are m (mass in kg), g (gravity in m/sec2), d (distance raised in meters).The work is expressed in joules, or kg-m2 / sec2.W (joules) = (20)(9.81)(.5) = 98.1 joules

It could be positive or negative. For example: Positive: someone who forces and pushes things to get done or forces and pushes to accomplish something. or Negative: someone who pushes everyone or everything to get what he/she wants out of it by force which often is not a positive thing. many kids have this personality now a days.
The answer to this question would also depend on 2 other factors, namely weight and speed. Seeming that these factors are not stated clearly in the question, one can not give an exact answer to it. But let's not get to complicated aboud it and just say that the question is ment under the terms of the most common used factors, which would give a weight of '1 kilogram' and a speed of '1 meter a second'..so then the question would be: How many Joules of work are done on an object 'with a weight of 1 kilogram' when a force of 10 N pushes it 'over' a distance of 5 m 'at a rate of 1 meter a second'? That would be: 1 kg.m/s = 1N 1 N.m/s = 1J So: 10 N x m/s = 10 J x (5 x 1m/s) = 50 J "force x distance / time"
"Newton" and "Joule" were different people, with different names and different spellings, who lived in different countries at different times, investigated different questions, and found different answers. That's a tip-off that the units named for them are completely different things, and can't be converted into each other. 'Newton' is a measure of force. If it pushes through a distance, then (energy) is produced, equal to the product of the number of Newtons multiplied by the distance in meters, and expressed in Joules. If the force pushes against a brick wall and doesn't move through a distance, there are a lot of Newtons there, but the number of Joules of energy produced is zero.
