A moving company uses a 5-meter long ramp to help load boxes into a van. What will most likely happen if the company uses a ramp with a length of 10 meters to lift boxes into the same van?
The amount of work accomplished will stay the same, and it will require the same amount of effort force.
The amount of work accomplished will be doubled, and it will require the same amount of effort force.
The amount of work accomplished will stay the same, and it will require half as much effort force.
The amount of work accomplished will be half as much, and it will require twice the effort force.
What is input force?
the resistance force
the force the machine exerts on the object
the force of gravity on the object
the force you exert on the machine
Which of the following correctly identifies the output force?
A
B
C
