How do you calculate the work done on an object when you push it?(1 point)
You subtract the force you apply from the distance over which you are pushing.
You multiply the force you apply by the distance over which you are pushing.
You divide the force you apply by the distance over which you are pushing.
You add the force you apply to the distance over which you are pushing
You multiply the force you apply by the distance over which you are pushing.
120 joules
The total amount of force is less, although the distance traveled is greater.
It allows objects to be lifted with less force and applied in a downward direction.
the amount of energy used to move an object
to change the direction of the force needed to move the block
A lever is a type of simple machine made of a bar that pivots on a fixed point called a fulcrum, which reduces effort needed while producing more work to move a load.
force = work / distance
the point where a lever pivots
a car that traveled 25 kilometers on 1 liter of gas
Machines must overcome forces of friction.
