What does an object need before it can perform work?
In order for work to be done on an object, the object must move some distance as a result of your force.
What is the resistance force or the work a machine dose to move an object over some distance?
Resistance force is the force that an effort force must overcome to work on an object by way of a simple machine.
Which activity describes work being done on an object?
A person pushing a box across a floor:· Mass of box = 20 KG, Weight of Box = 196.2· Distance moved in the direction of the force = 2m· Work Done = Force X Distance ( in the direction of the force), 196.2 X 2= 392.4 Joules
Why the output force exerted by a rake must be less than input force?
because you need the force to move it over some distance
What is a examples of forces?
Some exmples of forces are- an object begining to move an object speeding up an object begining to slow down or stop moving an object changing direction an object remaining still
You do on an object when you exert a force on the object that causes the object to move some distance?
You do work
When do you do work?
when you exert a force on an object that causes the object to move some distance.
In scientific terms when do you do work?
When you exert a force on an object that causes the object to move some distance .
What is the definition of work'?
Is done when a force exerted on an object causes that object to move some distance; equals to force times distance; measured in joules (j)

What does a force have to be than friction?
If you wish to actually move an object, some other force on the object has to be greater than the force of friction.

How much work is done with 200N of force in unsuccessful effort?
Work = force x distance. If the object doesn't budge, no energy is transferred (no work is done). Some energy may be wasted, but no work is transferred.Work = force x distance.

The force that is needed to move somethimg is proportional to what?
The force needed to accelerate an object at some rate is proportional to the object's mass.The object may be moved by as small a force as you want. It just won't accelerate at a very high rate.
