Energy
The energy of motion
What is kinetic energy?
Tendency of an object to do nothing or remain unchanged
What is inertia?
Length of one complete cycle of a wave
SI unit for measuring the frequency of a wave
What is Hertz?
The amount of matter in an object
What is mass?
The rate velocity changes with time
What is acceleration?
This type of wave is a wave in which the particles of the medium are displaced in a direction parallel to the direction of energy transport
What is longitudinal wave?
The value of gravity on Earth
What is 9.8 m/s2 ?
This type of energy is the stored energy an object has because of its position or state
What is potential energy?
This is defined as speed with direction
What is velocity?
Type of wave in which the particles of the medium are displaced in a direction perpendicular to the direction of energy transport
What is transverse wave?
Point on a medium through which a longitudinal wave is traveling that has the maximum density
What is compression?
A rock falling off a cliff is an example of this type of energy
What is kinetic energy?
A ball rolling on a surface will come to a rest due to this force
What is friction?
This part of the wave is the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position
What is trough?
This part of the wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position
What is crest?
A stretched rubber band (right before popping it) is an example of this type of energy
What is potential energy?
20 N force moves a body with an acceleration of 2 m/s2 . What is it's mass
What is 10kg?
The maximum amount of displacement of a particle on the medium from the rest position
What is amplitude?
How much force is needed to prevent a body of mass, 10kg, from falling
What is 98N?
