Newton’s Three Laws of Motion
- Inertia
- Acceleration
- Action and Reaction
acceleration is
force over mass
Newton’s Law of Universal Gravitation
- the greater the mass, the greater the force of attraction
- the greater the distance, the less force
amount of matter
mass
pull of gravity
weight
amount of space
volume
compactness; how compact the particles are; amount of matter per unit volume
density
True or False: the higher its density, the lower its volume
true
True or False: the faster, the higher the kinetic energy
true
True or False: the higher the position, the higher the potential energy
true
change in momentum
impulse
impulse = force x time
3 modes of heat transfer
- conduction (solids)
- convection (liquids and gases)
- radiation (vacuum)
Law of Conservation of Momentum
total momentum is conserved before and after collision when there is no net external force
rate of flow of charges
current
opposition to the flow of charges
resistance
potential difference that causes charges to flow
voltage
voltage =
current x resistance
all resistors connected in a line where there is only one path
series circuit
more than one path for current to travel through
parallel circuit
highest point in a wave
crest
lowest point in a wave
trough
the length of a complete wave
wavelength
the number of waves per unit of time
frequency
the height of a wave
amplitude
the time duration for a single wave
period
True or False: whichever color seen is the one reflected; all others are absorbed
true
bouncing of waves
reflection
bending of waves
refraction
spreading out of waves
diffraction
combination of waves
inetrference
true or false: mechanical energy is equal
true
