Johnny does an experiment where he takes a balloon and rubs it on a cloth.It makes his hair stick up and stick on the balloon.What is making it do this?
Static electricity energy
thermal energy
solar energy
kinetic energy
In class Sally and her friend did an experiment.They put water on the plate and put the lemon in the water with three matches on the lemon,They then lit the matches and put the cup over it and saw the water being sucked up into the glass,Why?
The oxygen was used by the fire so then it just got sucked up
The water just went up
The oxygen was used by the fire and when it was gone the liquid rises in to the cup to fill the rest of the volume.
Idk

convection
radiation
conduction
heat transfer

Definition of compound machine:A machine that reduces the force needed but is made with two or more simple machines.Which of these is an example of a compound machine?
scissors
pulley
inclined plane
wedge
True or false: If someone was stretching a rubber band and let it go,would it be elastic potential energy to chemical potential energy?
True,because it goes from elastic and it is still so it is potential,to in motion which is kinetic to chemical.
False,because it has no motion so potential and it is a elastic energy, to in motion so kinetic and the same elastic it had.
What kind of energy does a battery have?
chemical
mechanical
electrical
potential
If someone were to go on a run would it be work?
Yes,because they are applying force and a distance is being made.
No,because they are not applying force.
What energy does a generator change and what is it after it changes?
Mechanical to Electrical energy
Electrical to Mechanical energy
doesn't change anything
If somebody were to crank a handle and spin it so the turbine would spin,what energy would they be using?
chemical
mechanical
potential
kinetic
What energy change occurs in a toaster when it is turned on?
electrical to heat and potential
electrical to heat and kinetic
heat and sound to electrical
electrical to heat and sound
True or False:The Conservation of Energy law states:Energy can not be created nor destroyed
True,because energy can only be changed from one form to another.
False,because energy can be created like when you run you create kinetic.
What energy flows threw an electrical circuit?
electrical energy
potential energy
kinetic energy
chemical energy
