Heat Transfer
energy from the sun reaches Earth through the process of:
radiation
energy stored in food and fossil fuels (oil, gas)
chemical
define speed:
distance traveled over time
what is kinetic energy?
energy of motion
Every action has an equal and opposite reaction describes which one of Newton's law of motion?
Law #3
heat transfer between solids due to CONtact is known as
conduction
energy that travels through wires and powers your appliances
electrical
define: motion
change in position relative to a fixed point
what is potential energy?
stored energy
What is the formula for calculating force?
F=mass(acceleration)
f=m(a)
what is the heat transfer in liquids and gases?
convection
ice cream melting is a form of what type of energy
heat energy
define: Newton's 1st Law
inertia
potential energy relies on ...
weight and height
A car speeding up, slowing down, or making a turn describes
acceleration
what are convection currents?
transfer of heat in liquids and gases due to differences in density
the energy stored in the nucleus of an atom is
nuclear energy
Define: vacuum
space
kinetic energy depends on :
mass and velocity (speed)
A change in velocity over a certain amount of time describes:
acceleration
what is an example of radiation?
what is an example of conduction?
roasting marshmallows
frying an egg in a pan
this energy is able to travel through space
electromagnetic
define: Newton's 3rd Law
action and reaction forces
potential and kinetic energy are forms of what type of energy
mechanical energy
this is a property of all moving things
momentum
