the number of moles of a particular particle or molecule in one liter of another substance

Question 17

velocity

Answer 17

an objects speed AND direction

Question 18

acceleration

Answer 18

rate at which the velocity of an object changes with respect to time

Question 19

force

Answer 19

a push or a pull

Question 20

balanced forces

Answer 20

forces that combine to produce a net force of zero

Question 21

zero net force

Answer 21

there is no net force and therefore no acceleration

Question 22

non-zero net force

Answer 22

there is a net force, so acceleration is possible

For every action there is an equal and opposite reaction

Question 25

linear momentum

Answer 25

the mass of an object times its velocity

Answer 27

energy that is being used or converted; results in the displacement of an object in the direction of an applied force

Question 28

law of conservation of energy

Answer 28

the law explaining that energy cannot be created or destroyed; it can only be transferred or converted from one form to another

Question 29

Oscillation

Answer 29

a repetitive motion that usually occurs about a center point

Question 30

electromagnetic wave

Answer 30

a combination of an oscillating electric field and an oscillating magnetic field; electromagnetic waves can travel through both the vacuum of space and a medium

Question 31

equilibrium

Answer 31

a position or state to which an oscillating object eventually returns after a disturbance is gone

transverse wave

Answer 34

a wave where the oscillation is perpendicular to the direction the wave is traveling

Question 35

longitudinal wave

Answer 35

a wave where the oscillation is parallel to the direction the wave is traveling

Question 36

equilibrium position

Answer 36

the center point of a wave where no movement is occurring

Question 37

crest

Answer 37

the highest point of a transverse wave

Answer 38

vertical distance from the equilibrium to the crest or the equilibrium to the trough of a transverse wave

Question 39

wavelength

Answer 39

the horizontal distance after which the wave repeats itself in space

Question 40

period

Answer 40

an interval in time after which the motion of a particle on the medium starts to repeat

Question 41

frequency

Answer 41

the number of oscillations the wave makes in a given amount of time, typically a second

Question 42

trough

Answer 42

the lowest point of a transverse wav

Answer 43

when particles of matter are pushed closer together

Question 44

expansion

Answer 44

when particles of matter are pulled away from each other
