**Answer**: a - by reducing the amount of force required

**Question 26**: If Mr. Jones was moved from Earth to the moon, what would change?
**Answer**: a - weight
(Note: Mass remains the same, but weight changes due to the difference in gravitational pull)

**Question 27**: Which of the following has the greatest potential energy?
**Answer**: c - a 10 kg eagle's nest full of eggs at the top of a tree
(This is because potential energy depends on the height and the mass)

**Question 28**: The faster an object moves the _____________ kinetic energy it has.
**Answer**: a - more

**Question 29**: A(n) is created by passing current through a coil of wire wrapped about an iron core.
**Answer**: c - electromagnet
