Which best describes the speed and velocity of the graph?
a) both speed and velocity are changing.
b) the speed and velocity remain constant.
c) the speed is constant and velocity is changing.
d) the velocity cannot be determined from the graph.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

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.
