Question 1 • TN-Physical Science SC 26-27 (For Credit)
A machine can make a task easier by changing how much force you apply, changing the force’s direction, or changing the distance over which the force acts. For example, a ramp reduces the force needed by spreading the work over a longer distance. A machine does not reduce the total work in an ideal system, and changing the time is not one of these basic ways it makes work easier.
