Work is equal to force times distance of displacement:
W = F * r (assuming the force acts in the direction of displacement)
To calculate work needed to move a car 250 m, you need to know the force that is necessary to do so.
The work done in pushing the car would be 1000 N * 10 m = 10000 J (Joules) of work. Work is calculated by multiplying force applied by the distance over which the force is applied.
Work is force exerted over a distance. If I pushed on my car really hard and it did not move, no work was done. If my car started going without any force being exerted on it, which would be miraculous, no work would have been done.
Work done is equal to force multiplied by distance in the direction of the force. In this case, work done on the car is 12000 N * 2 m = 24000 J.
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
yes it does, but it is somewhat of an art. when done correctly it can have amazing effects on the car...but if done wrong it can have amazingly bad effects
When you take you car to mechanic to have work done and the mechanic loans you a car until yours is ready, that loaned car is a courtesy car.
The work done by the two boys is zero, since the force they applied did not result in any displacement of the car. Work is defined as force multiplied by displacement, and in this case, since the car did not move, no work was done.
Some examples of work physics problems that involve calculating the amount of work done include lifting a box against gravity, pushing a car up a hill, and pulling a sled across the snow. These scenarios require calculating the work done by applying a force over a distance.
As long as it takes to get the job done.
Since the car does not move, the boy does no work on the car. Work is only done when a force causes an object to move in the direction of the force.
Ask your friends where they have their vehicles repaired and if they are satisfied with the work done and the price.
Work is calculated as force multiplied by distance. In this case, the work done to move a 10000 Newton car 20 miles would be 200,000 Joules. (Work = force x distance)
