MULTIPLE SELECT QUESTION
45 sec • 1 pt
Gravitational Potential Energy can be increased by increasing the ________ of the object. (Choose all that are correct. May be more than 1 answer)
mass
height
speed
volume
temperature
Answer explanation
The formula for gravitational potential energy is PE = mgh
m is the mass of an object
h is the height of an object
g is a constant for Earth's gravity that doesn't change (9.8 m/s/s)
so increasing mass or height would make the PE larger
