If a machine decreases the distance an object moves, it must also _____.
1 answer:
increase the force needed to move the object
Explanation:
If a machine decreases the distance an object moves, it must also increase the force need to move the object.
A machine is a device that is used to do work with a little energy input.
Work done = force x distance
We see that to do more work, a lot of force must be applied to move a body through a greater distance.
If the distance is reduced;
Distance =
More force must be applied to measure up for the distance and make the machine more efficient.
