Waves
A slinky; like a sound wave is considered
longitudinal
Stored Energy due to height
potential energy
Gravitational force is stronger when objects are
closer; less distance between them
A wave that goes up an down like a string or ocean wave is
transverse wave
Law of conservation of energy states
energy can't be created or destroyed just transferred
What types of waves can travel through empty space ( example; light )
electromagnetic
energy of motion
kinetic energy
3 forces that act at a distance
magnetism, electricity and gravity
Object A is 5 meters high and object B is 2 meters high, which will have more kinetic energy when they start to move
object a
law of conservation of mass
matter can't be created or destroyed just changed
What two properties of a wave affect color
frequency and wavelength
potential and kinetic energy combined
mechanical energy
these two types of forces are used in an electromagnet
electricity and magnetism
heat always flows from ______ to _________ untill everything is same temperature
newtons 1st law of motion
law of inertia
A signal that uses on or off or 1 and 0 is what type of signal
digital
the ability to do work
What are magnetic field lines
Magnetic field lines are lines we can not see and are where the magnetic field is flowing. We can use iron filings to show us where the lines lay so that we can see how magnetic fields interact.
the faster the particles of an object move the greater these two types of energy
kinetic and thermal
newtons second law of motion
force = mass times acceleration
Barry White has a low pitched voice because
energy is measured in
joules
What is created when a bar magnet is moved through a wire coil
electricity
describe one thing you learned in 5th grade science
answers may vary
newtons 3rd law of motion
