What kind of energy at the top? Due to ??
What happens to height as it is released?
What happens to PE?
What happens to speed as it drops?
What happens to KE?
What kind of energy does it have at the bottom?
The pendulum has a mass of 0.80 kg.
Calculate the PE at the top.
Calculate the KE at the bottom.
PE __________ KEconverted
KE __________
to building
transferred
How does the unpacked snow do work on the skier?
Did you use these terms: force, distance, energy transfer?
Write the equation for GPE?
Calculate the mass of the skier. Use the PE at the top.
GPE =
KE =
mgh
½ mv2
How does the ball acquire KE when it is tossed in the air?
What happens to the KE as the ball moves up in the air?
Did you use the terms:
KE, PE, converted,
height, speed
Did you use the terms:
Energy transfer, work, force, distance
