forces and motion
The state in which one objects distance from another is changing
what is the definition of motion?
The product of the mass of an object and its velocity.
what is momentum?
how often a or quickly a wave passes by
what is frequency?
another form of energy that is created by the movement of electrons.
what is a magnetism?
a push or pull on an object
What is a force?
The property of a system that enables it to do work.
what is energy?
changes in speed of light/temperatures and densities of the same mediums
what is a refraction?
Metal, water, and wires
what is a open conductor?
final velocity-initial velocity/time
what is acceleration?
A collision in which the colliding objects become distorted, generate heat, and possibly stick together
what is an inelastic collision?
20-20000 hertz
what is the human hearing range?
Prevents the flow of electrical energy
what is a open circuit?
9.8 m/s
what is the gravitational pull on earth?
1/2 momentum x velocity2
what is kinetic energy?
A wave in which the particles of the medium vibrate parallel to the direction the wave is traveling
what is a longitudinal wave?
In this circuit there is only one pathway for the electrical energy
what is a series circuit?
acceleration= force/mass
what is newtons second law?
force x distance **hint: measured in joules
what is work?
what is wave speed
states that the current passing through a conductor is proportional to the voltage over the resistance.
What is ohm's law?
