This type of energy can be transferred in three different ways: 1) direction contact through collisions (also called conduction), 2) through a fluid making a current created by less dense fluids floating and more dense fluids sinking (also called convection), and 3) by waves traveling with or without a medium (also called radiation)
this type of energy is often found in things like batteries or food
this is radiant energy from the sun; it's the only kind of energy we can see with our eyes
this has to do with the speed of an object and how much mass it has; basically how the object is moving
this is energy that is transferred by the movement of electrons through a conductor: the electrons create a current.
this can be either kinetic or potential and has to do with the energy of position and motion of an object
this is the energy found in the nucleus of an atom
this is the term used when energy changes from one form to another
this type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band
this type of energy travels through vibrations on waves

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
