When object 1 came into contact with object 2, object 2 got warmer. what can be concluded about the objects before they came into contact with each other?

object 2 did not have thermal energy.
object 1 had faster-moving particles
object 1 had less thermal energy
object 2 had fewer particles

Object 1 had faster-moving particles

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.
