-- You say to yourself "Work is force times distance".
-- Then you ask "What's the force ?", you look at the question, and you say "47 N".
-- Then you ask "What's the distance ?", you look at the question, and you say "0.25 m".
-- Then you remember that "Work is force times distance", and you calculate (47 N) x (0.25 m) = 11.75 joules . -- As you hand in the test, you say to yourself "The mass of the pencil and
the resisting force of friction were only there to confuse me, but they failed."
--Then you smile :)

How to calculate the normal force acting on an object held against a wall given mass and force?
Force of horizontal normal to the wall reaction on the object will be exactly equal to the force you're pushing it against the wall with.
What are the forces act on a retaining wall?
Outward Force: dirt pushing against retaining wallInward Force: atmospheric pressure, the retaining wall pushing against the dirtDownward Force: gravity, atmospheric pressure, the retaining wall pushing against the earth.Upward Force: The earth pushing against the retaining wall.
Normal force is supplied by what?
A surface pushing up, equal and opposite to a force pushing against it
What does lift do to the airplane?
Lift acts against the force of gravity, pushing the aircraft up.
How friction is useful in pushing a car?
If you are behind a car, about to push it forward from a resting position, you will need to exert a force on the car to accelerate it from resting position. While you are pushing against the car, however, there will be a reaction force pushing back at you. In order to produce a large net force against the car without being pushed backward yourself, you need to increase the friction of your feet against the ground...so that the frictional force between your feet and the ground prevents you from sliding backward. The combinations of the frictional force and your force pushing forward against the car will cause the car to move forward. The frictional force of the car being moved from resting position also has to be overcome, of course.
How do you calculate the net force when two people are pushing in the same direction?
You just add the forces in this case.
When you push against a wall with your fingers they bend because they experience a force. What is this force?
It is the force of the wall pushing against your fingers. This is related to Newton's Third Law.
There are 2 forces acting on Gary the goat one force is his weight and the other is the rock pushing against his feet What is force A and what is force B?
gravity
What is a good example of input force?
Someone pushing against a lever.
What provides the centripetal force for a car driving on a circular track?
The road, pushing against the tyres.
When airplane is moving in circular motion in the sky which force act as necessary centripetal force?
That would be the air pushing against the airplane's wings.
A sailboat is traveling at a steady speed of 13 mph. The force of the wind pushing against the sail is the opposing force of the water resistance.?
Equal to.
