Circle a machine that makes work easier by increasing the distance over which force is applied.
a car jack
pliers
a ramp
a pulley system
You use a fixed pulley system to raise a flag up a flagpole. This is an example of a machine that:
changes the direction of a force
increases the force
increases the distance
all of the above
The force you apply to the handle of a wrench is called the:
output force
input force
direction of the force
ideal mechanical advantage
Work is made easier by machines like a can opener, a ramp, and a car jack because:
the input force is greater than the output force
the output force is greater than the input force
the input distance is greater than the output distance
none of the above
The amount by which a machine can change an input force is called:
the output force
friction
mechanical advantage
an ideal machine
