What is the formula for kinetic energy? KE = mv 2 2
Why does a person standing at the top of a hill have more total energy than a person standing at the bottom? More gravitational potential energy
What is the term for the energy of moving electrons? Electrical energy
What two energy types make up total mechanical energy? Kinetic energy + Potential energy
What is the gravitational potential energy of a diver who weighs 600 N on a platform 12 m off the ground? 7200 J
What is the law of conservation of energy? Energy cannot be created or destroyed but can be changed from one form to another
What is the unit for measuring energy? Joules
Why can’t perpetual motion machines work in real live? Any time there is an energy conversion, some energy is converted to thermal energy. Friction contributes to this.
What are three main types of fossil fuels? Coal Petroleum Natural Gas
What is the term for the energy of a compound that changes as its atoms are rearranged? Chemical energy
What is the term for the energy caused by an object’s vibrations? Sound energy
What is the energy of movement called? Kinetic energy
What are fossil fuels? Thermal energy
What type of energy does a stretched rubber band hold? Elastic potential energy
What is the term for the energy generated by changes in the nucleus of an atom? Nuclear energy
What is the kinetic energy of a 5000 kg elephant running towards Mrs. B’s car at 6 m/s? 90, 000 J
What is the formula for gravitational potential energy? GPE = weight x height
What is the term for the kinetic energy due to the random motion of particles that make up an object? Thermal energy
How does a light bulb convert energy? What does it start with and what does it end up with? Electrical energy —> Light energy, Heat energy, Sound energy
What is an energy conversion? a change in one form of energy to another
What is a renewable resource? (Definition, not example) a natural resource that can be replaced at the same rate at which the resource is consumed
What is the term for the energy produced by the vibrations of electrically charged particles? Light energy
What is the total mechanical energy of a 400 N person (40 kg) who is 10 m high on a hill, moving at 4 m/s? 4320 J
What are fossil fuels? nonrenewable energy resources formed from the remains of organisms that lived long ago
How do we turn coal into electricity? Coal is burned, water is heated to steam, steam turns the turbine in a generator
Is nuclear energy a renewable or nonrenewable resource? Nonrenewable
