Motion
A straight line with an arrowhead to show direction
What is a vector?
? = force x distance
What is work?
A neutral atom has the same number of these two elementary particles
What are protons and electrons?
Radio waves and x-rays are an example of these types of waves.
What are electromagnetic waves?
An informed prediction that can be tested.
What is a hypothesis?
? = Distance/time
What is speed?
the energy of motion
what is kinetic energy?
The elementary particle that has no electric charge
What is a neutron?
The length of one complete
wave, usually in Angstroms or nanometers
what is wavelength
An explanation of why certain events take place and if they obey a certain law.
What is a theory?
? = speed/time
What is acceleration?
The energy of position
What is potential energy?
The law that relates current and voltage to resistance.
What is Ohm's Law?
The bending of light when the speed changes as it enters a new medium.
What is the refraction?
A rule that holds true at all times and places within its range of applicability.
What is a law?
An influence that can change the speed or direction of motion of an object through pushing, pulling, lifting, etc.
What is a force?
When outside forces are not present, the combined total momentum of objects in motion does not change.
What is the conservation of momentum?
? = current x voltage
What is power?
The apparent change in frequency of a wave in relation to an observer moving relative to the wave source
What is the Doppler Effect?
A simplified version of reality or a representation that can be tested to study a natural phenomenon.
What is a model?
For every action there is an equal and opposite reaction. one of three laws
Newton's Third Law
A device that allows you to do work with less force.
What is a simple machine?
What is a parallel circuit?
This type of wave causes particles in the medium oscillate in a direction PERPENDICULAR to the direction of wave propagation
What are transverse waves?
Fractional quantity relating equivalent units.
What is a conversion factor?
