gravity
the ability to do work is ....
energy
what is collision
when things hit each other
what is the energy we can see
light energy
what energy caused by vibration
sound energy
what is the force that slows object down
friction
what are the two types of energy
potential and kinetic
what is energy transfer
when energy moves from one object to another
what is the energy related to the movement of particles
thermal energy
what energy changes in a TV
from electric to light and sound
the tendency of an object in motion to stay in motion is called
inertia
a girl dancing has what type of energy
kinetic
why do we hear loud noise in a car crash
some of the energy transformed into sound energy
give example of a nuclear nergy
the sun
who is the scientist who discovered gravity
newton
what force can do to an object
make it move , stops , change direction or shape
what do we call speed with direction
velocity
true or false the bigger the object the less energy it has
false
the battery has what type of energy
chemical
what is the energy in the charged particles
electrical
a book on a table has balanced or unbalanced forces
balanced
what is potential energy
the stored energy in an object
what does the law of conservation of energy says
energy can not be created or destroyed , only changes form
list the types of energy
chemical, nuclear, light, sound , thermal, electrical
example of a non-contact force
gravity
