Waves
Sound
What is a longitudinal wave?
kgm/s
What is momentum?
Energy cannot be created or destroyed. It simply changes forms
What is Law of conservation of Energy?
p = mv
What is momentum
Electromagnetic waves
What is a transverse wave?
m/s2
What is acceleration?
mass = 10 kg
height = 10m
acceleration due to gravity = 9.8 m/s/s
What is 980 J?
Directionally proportional: as mass increases, momentum also increases.
What is the relationship bewteen momentum and mass?
Water Waves
What is a transverse wave?
m/s + direction
What is velocity?
A rock resting at the top of a cliff
What is potential energy?
directly proportional: as velocity increase, momentum also increases
What is the relationship between momentum and velocity?
A wave that travels in a straight line
What is a longitudinal wave?
1kgm/s2 = 1 Newton
What is force?
a rock falling to the ground
What is kinetic energy?
more mass and more velocity
What is greater momentum?
The only wave not needing a medium to travel.
What is an electromagnetic wave?
1Nm = 1 Joule = 1 J
What is the unit for energy?
As potential energy increases kinetic energy decreases
What is the Law of Conservation of Energy
kgm/s
What is the unit for momentum
