Motion
This is the distance an object travels plus the direction from the starting point.
What is displacement?
This is a push or pull on an object
What is a force?
Energy an object has due to motion
What is kinetic energy?
This is an everyday example of a transverse wave
What is light?
This is the rate of flow of electrons moving past a fixed point in an electrical circuit.
What is current?
This principle states that objects will stay in motion unless it is acted upon by an outside force.
What is Newton's first law of motion?
This force keeps the moon in its orbit
What is gravitational force?
A student pulling a rubber band back is an example of this kind of energy
What is elastic potential energy?
This is the maximum displacement of the medium from its rest position.
What is amplitude?
Each atom or molecule has a magnetic field. When all of these are aligned, what kind of magnet do you have?
What is a ferromagnet?
This is the rate at which an object is moving at a given moment in time.
What is instantaneous speed?
This force opposes the initiation (or start) of motion
What is static friction?
This is energy stored in the bonds of molecules. This differes from nuclear energy, which is energy stored in the nucleus of an atom.
What is chemical potential energy
What is intensity or amplitude?
this is a material with a high resistance, stopping the flow of electrons.
What is an electrical insulator?
This is the ratio of the total distance traveled to the total time of the trip
What is average speed?
This force holds the nucleus together
What is the strong nuclear force?
This machine changes the direction of the applied force (down) in order to pull an object up.
What is a pulley?
An increase in frequency causes these changes in wavlength and energy.
Wavelength decreases
Energy increases
Objects can become charged by these three ways.
What is friction, conduction, and induction?
Acceleration is caused by these three things.
The object speeds up
The object slows down
The object changes direction
This is the motion of an object when it is only under the influence of gravity
What is free fall?
These energy transformations occur when we eat food! (Hint: Start with one, and it can be transferred or transformed into 3 kinds of energy)
What is chemical potential energy transforming to more CPE, kinetic energy, and heat.
This effect, first described in the 19th century, explains why light from distant galaxies shifts toward red or blue depending on their motion relative to us.
What is the doppler effect?
The earth's magnetic field protects the earth from this
