What does a machine change to make work easier? Select three options. 1) the amount of work done 2) the amount of force applied 3) the time needed to do the work 4) the direction of a force 5) the distance over which over a force is applied
Added by Kim S.
Step 1
A machine can change the force or distance, but the total work done remains the same. So, this option is not correct. 2) The amount of force applied: A machine can change the amount of force applied, making it easier to do the work. For example, a lever can help Show more…

if a simple machine reduces the strength of a force, what must be increased?
Madhur L.
Determine if the amount of POWER is MORE or LESS? 1. An engine can lift an object faster. 2. Someone takes more time to push a car. 3. You take the same amount of time to do more work. 4. Same distance, same time, more force. 5. Same distance, same force, more time. 6. Same force, same time, less distance. 7. Same force, same time, more distance. Match the units with the correct description. 1. Force 2. Work 3. Power 4. Distance 5. Time 6. Mechanical Advantage A. 4.0 B. 25 J C. 30 m D. 12 N E. 15 s F. 8 W
