Back 3

scalar quantitiy because it involves just a number

Front 4

Displacement is said to be a

Back 4

vector quantity because it involves a direction

Front 5

Speed

Back 5

The rate of motion at which an object travels in a certain amount of time

Front 6

Formula for speed

Back 6

s=d/t

Front 7

speed is said to be

Back 7

scalar
No direction

Front 8

Velocity

Back 8

speed and direction
Vector quantity
V =d/t with direction

Front 9

Acceleration

Back 9

change in an object's velocity over time.
a = triangle symbol v/t
triangle symbol = final velocity-initial velocity
a= (final velocity-initial velocity)/ t

Front 10

Momentum

Back 10

P= mv
P= momentum
M=mass
v=velocity

Front 11

Impulse

Back 11

is a force (that is applied to an object over time.
Impulse can also be thought of as a change in momentum, the mass time the change in velocity. M(Vi - Vf)

Ft = m (Vi-Vf)
Ft=Impulse

Front 12

1. Newton first law

Back 12

involves inertia, a property of matter by which an object in motion tends to continue traveling in a straight line, wheras an object at rest stays at rest unless that object is acted on by a force.

Front 13

Newton's second law

Back 13

concerns the relationship between the forces applied to an object and the acceleration of the object. THe greater the force applied to the object, the greater is its acceleration. THe equation that shows this relationship is F=ma. THe unit of measure for force is the Newton (N). THis unit is a derived unit, which comes from multiplying the unit of mass, kg, by the unit of acceleration, m/s(squared). Multiplying the two, you get kg x m/s(squared). One caution: if an object is moving at a constant velocity (vi-vf) =0 then it is not being accelerated and the force needed to achieve this constant velocity is also equal to zero.

Front 14

newton's third law

Back 14

says that when one object applies a force to a second object, that second object applies an opposite and equal force to the first object.

Front 15

work

Back 15

the work done on an object is defined as the force applied to the object multiplied by the distance the object moves.
W=Fd
The unit of measure for force is the newton
unit of measure for distance is the meter,
so the unit of measure for work is the newton-meter (N x M)

Front 16

power is related to work in that power is

Back 16

the amount of work done in a certain amount of time.
P= W/t
When you divide newton meters bys seconds, you get N x m/s (or the unit called the watt, W)

Front 18

Energy can be either

Back 18

Potential-stored

Front 19

the formula for calculating gravitational PE (Potential energy)

Back 19

PE= mgh

Front 20

Formula for calculating kinetic energy

Back 20

KE=1/2mv(squared)

The unit of measure for both kinetic and potential energy is the joule (kg x m(squared)/ S (squared)
S=seconds

Front 21

conserved

Back 21

Energy is never created or destroyed

Front 22

The distance b/w two crests (or two troughs)

Back 24

wavelength (looks like ^ almost)

Front 25

frequency

Back 25

number of complete waves that pass through a point over a given amount of time

Front 26

multiplying the frequency of a wave by its wavelength gives

Back 26

the velocity of the wave
v=F ^

Front 27

Transverse waves

Back 27

have vibrations that are perpendicular(at right angles) to the direction in which the wave is moving

Front 28

Longitudinal waves

Back 28

have vibrations that are moving in the same direction as the wave

Front 29

Light can be thought of as either

Back 29

a wave or a particle. This is called the "wave-particle duality of light."

Front 30

light particles are

Back 30

photons

Front 31

diffraction

Back 31

takes place when a wave that is spreading out hits an object and as it continues to travel, bends around the object.

Front 32

Dispersion

Back 32

breaking up of white light into its colors. occrurs when light pass through a prism.

Front 33

current (I)

Back 33

FLow of charge from one terminal of a circuit to another. amount of charge that passes through a point per second. The unit of measure for current is coulombs/second or just ampers (A)
