Answer 17

speed

Question 18

the amount of matter an object has in it

Answer 18

mass

Question 19

the quantitative relationship between two amounts

Answer 19

ratio

Question 20

the sum of potential energy and kinetic energy. ME = KE + PE

Answer 20

mechanical potential energy

Question 21

what is the equation for mechanical potential energy
