1. if work stays the same and distance is increased, then ______ force

a) less
b) more
c) the same
d) no

Explanation:

Question 1

Kinetic energy is defined as the energy an object possesses due to its motion. Potential energy is stored energy (e.g., due to position), chemical energy is energy stored in chemical bonds, and magnetic energy is related to magnetic fields. So the correct answer is a.

In physics, work is defined as the transfer of energy that occurs when a force causes an object to move. Space, time, and density are not what is transferred during work. So the correct answer is c.

Potential energy is the energy stored in an object due to its position (or configuration). Kinetic energy is due to motion, chemical energy is from chemical bonds, and magnetic energy is from magnetic fields. So the correct answer is b.

Answer:

a) Kinetic
