Walt : we had a paper plane competition which one go's the farthest the highest and by the way we wrote about how airplanes.I find that hard is brainstorming and demonstrating .
we are learning about Forces
Balance
Balance is a force when both side are equal they balance and balance causes no motion Balance Is when two or more things are equal.when forces are balanced there Is no motion .If there is motion then it means the forces are unbalanced.
Friction
Friction is the opposition of motion, also friction is a force. If you rubs your hands together they cause friction and it makes it harder to rub them.
Movement
Movement Is when there Is Motion,Or when something changes position. Forces make movement happen.Movement needs force to happen.If you apply more force the Movement
Accelerated.
Conclusion
Each force uses motion which is movement and acceleration, friction is a force that slows down like drag which is the opposite of thrust and last but not least balance when both side are equal they balance .
