True or False: Energy in a system can change constantly, but always the total amount is the same.
True
These are the two variables that kinetic energy is dependent upon
What are mass and velocity?
Name 2 types of kinetic energy?
what is light (radiant) energy, mechanical energy, thermal energy, electrical energy, sound energy.
This is the work done if you use a pulley system to lift a load of 500 Newtons vertically upward by pulling the rope a distance of 10 meters.
What is 5000 J?
What is kinetic energy?
On a rollercoaster, this is where your potential energy is the highest.
What is the top of the rollercoaster?

This is the potential energy of a 49 kg rock, on a ledge 138 m above the ground.
What is 66,267.6 J?
This is the type of energy a pendulum has while it's swinging at the peak of its swing and then the energy at the bottom.
Kinetic and then potential.
