Which statement best describes the relationship between forces?

a. magnetic and electrical forces are the most alike because they are both caused by positive and negative charges.

b. gravitational and magnetic forces are the most alike because they are both types of charges that occur in nature.

c. nuclear and magnetic forces are the most alike because they are both related to mass and weight.

d. strong nuclear force is most like electric because they are both related to distance.

the device is called “ rocket engine”

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
