What is the law of reflection?
angel of incidence + angle of reflection
What is diffraction?
The bending of light when going around a barrier
What is a chemical change?
a change in shape, size, and identity
What is the formula for momentum?
mass x velocoty
What is refraction?
the bending of sound light due to its surrounding
“shopping cart” law
2
What is power measured in?
watts
What is reflection?
light or sound bouncing of things
What is one example of refraction?
a straw looking different in water
work
force x distance (joules or newton meters)
power
work divided by time
mass
how much matter soimehting has
velocity
speed in a given direction
whats average speed
distance divided by time
newtons 1st law
an object at rest/motion will stay at rest/motion until an unbalanced outside force acts upon it
newtons 2nd law
force =mass x acceleration, change one variable it will affect another one
newtons 3rd law
for every action theres an equal and opposite reaction
atomic mass
protons + neutrons
protons always =
electrons
key trait of a sound wave
crest, trough, wave length, amplitue, rest line
energy conversions during a H20 balloon slingshot
The balloon slingshot is mechanical energy, when the balloon is in the pouch and being pulled back it is potential energy. It is then converted into kinetic energy when it is soaring in the air.
plant adaptation
flowers become more bright to attract pollinators
chemical properties and changes
A chemical property is how a substance reacts with something else. A chemical change is a change in the physical and chemical properties
How do u find the average speed?
Distance traveled divided by the time it took
What are some examples of chemical properties?
flammable objects, and oxidation
