What is the speed/ velocity formula?
S= d/t or Speed= distance/time
What is the formula for acceleration?
a= f.v.-i.v.
--------- or f= m x a
What is the forula for momentum?
p= m x v or momentum= mass x velocity
What is the formula for work?
w= f x d or work= force x distance
What is the formula for power?
p= w/t or power= work/ time
What is the formula for kinetic energy?
k.e.= 1/2(m)x(v)
k.e.= 1/2(mass)x(velocity)
What is the formula for gravitational potential energy?
g.p.e.= (m)x(9.8)x(h)
g.p.e.= (mass)x(9.8)x(height)
What is the formula for density?
D= m/v
Density= mass/velocity
Endothermic Reaction
A chemical reaction that requires heat
Exothermic Reaction
A chemical reaction in which heat is released to the surroundings
A substance that cannot be separated or broken down into simpler substances by chemical means
A subastance that changes the rate of a chemical reaction without being consumed or changed significally
The process in which light nuclei combine at extremely high temperatures, forming heavier nuclei and relasing energy
The process by which a nucleus splits into two or more fragments an releases neutrons and energy
Beta Particles
A charged electron emitted during certain types of radioactive decay, such as beta decay
Alpha Particles
A positively charged atom that is released in the disintergration of radioactive elements and that consists of two protons and two neutrons
Electromagnetic Induction
The process of creating a current in a cirquit by changing a magnetic field
Magnetic Field
A region where a magnetic force can be detected
The distance traveled by an object divided by the time interval during which the motion occured
The speed of a object in a particular direction
A quantity defined as the product of the mass and velocity of an object
Kinetic Energy
The energy of a moving object due to its motion
Potential Energy
The stored energy resulting from the relative positions of objects in a system
Gravitational Potential Energy
The potential energy stored in the gravitational fields of interacting bodies
The maximum distance that the particles of a wave's medium vibrate from their rest position
The distance from any point on a wave to an identical point on the next wave
The bouncing back of a ray of light, sound, or heat when the ray hits a surface that it doesn't go through
The bending of a light ray as it passes from one substance to another one with a difference in density
Contrast an element, a compound, and a mixture
An element can't be broken down to anything simpler. A compound can be broken down by heating and electrolysis. A mixture can be broken down by filtration, crystallization, or distillation
What is the difference between an endothermic and an exothermic reaction?
Endothermic, energy is absorbed (cold) and exothermic, energy is released (heat)
Name two things you could do increase the counting rate of a raioactive sample held a certain distance from a Geiger counter.
Use a larger sample, or move the counter closer
What is the source of the sun's energy?
Nuclear fusion H+H= He
Where does a bar magnet exert the strongest force?
At the poles
What is the primary cause of tides on Earth?
The Moon's gravitational pull
In what phase must the Moon be in for a solar eclipse to occur?
New Moon
In what phase must the Moon be in for a lunar eclipse to occur?
Full Moon
Name the six simple machines
*lever *inclined plane
*pulley *wedge
*wheel and axel *screw
Why do we see the phases of the moon?
As the moon revolves around the Earth the illuminated side of the moon is not always fully visible from Earth
What are the phases of the moon in order begining with full moon?
Full Moon, Waning Gibbous,
Third Quarter, Waning Crescent, New Moon, Waxing Crescent, First Quarter, Waxing Gibbous
What type o nuclear reaction is used to generate electricity in nuclear powerplants?
Describe divergent boundaries
Move apart
Describe transforming boundaries
Slide apart
Descrbe convergent boundaries
Move together
List the layers of the Earth, in order, from the crust inward.
Lithosphere, asthenosphere, outer core (liquid iorn), inner core (soid iron)
What is a convection current?
Movement due to the difference in density
warm air- less dense
cool air- more dense
Why does the Earth's inner core remaian solid even though it's very hot?
Pressure do to the weight of the crust and mantle, is so great that the atoms are forced together as a solid
Convection currents occur in which layer of the Earth?
