Motion
Kinetic energy
energy that is (being used/ is in motion)
Newtons first law
An object in motion stays in motion, and an object at rest stays at rest, unless acted upon by another force
sources of energy
Solar energy
Wind energy
Geothermal energy
Hydrogen energy
how temperature affect viscosity
Increasing temperature results in a decrease in viscosity, decrease in temperature increases viscosity.
the atomic theory contributions of Dalton.
calculated the first relative weights of atoms.
Potential energy
Energy that is (at rest/ not being used/ being stored)
Newtons second law
The force on an object is equal to its mass times its acceleration.
environmental effects of fossil fuels
produces large amounts of greenhouse gases
formula for density
ρ = m/V
the atomic theory contributions of Thomson.
Discovery of the electron.
Formula to calculate the speed
S= D/T
Newtons third law
For every action, there is an equal and opposite reaction.
the importance of the safety data sheet
contains information to help you make a risk assessment as required by the Control of Substances Hazardous to Health
how weight affects buoyancy
objects heavier than liquid (water(1) will sink
the atomic theory contributions of Rutherford.
made the new atomic theory to explain the better model of atom.
Formula to calculate kinetic energy
(KE) =1/2 M V2
the force acting on a rolling ball
friction
safety equipment
goggles, apron, gloves, fire blanket, eye wash.
how do particle movements change as matter changes states
the more solid the matter is the slower the particles. the less solid an object the faster the particles.
the atomic theory contributions of Bohr.
Bohr's model introduced the quantum mechanics.
Formula to calculate potential energy
P=mgh
formula to find weight
w = m x g
what are safety symbols for
to tell you if something is flammable, toxic, poisonous, hazards etc.
three types of movements of heat
conduction
convection
radiation
the atomic theory contributions of Chadwick.
discovered the Neutron in atoms.
