The american physical chemist gilbert newton lewis (1875-1946) proposed a unit of time called a jiffy. according to lewis, 1 jiffy is the time it takes light to travel 1 cm. (c= 2.998 x 10^8 m/s)
a) if you perform a task in a jiffy, how long does it take in seconds?
b) how many jiffys are in one minute?

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.
