Look at the following pictures that I posted. Click on one that you like best. Then, once you looked at the picture, explain where all of the force and motion terms are being displayed. Yes, you should include balanced and unbalanced, as well as, net forces. If someone else has already completely done one of the pictures, choose a different one, but feel free to correct someone who doesn't quite have it all.

the bmx bikes are moving from one direction to another. They use their speed and drectionin the race. Also, speed to be as fast as they can. from start to finish is the the distance they coverd. At the end of the race a person tell the finisher their time at the end of the race. They use direction to know when to turn. They accelerate on straight aways to cover a lot of track faster. Their referance point is from start to finish.They use speed and force to be a better racer. The gravity keeps them on the ground. Thrust helps them move the bike where they want it to go. Air resistance puts force on the rider when hes when he's peddlingThe tires cause friction on the track. The tire and rim cause static when the wheels rolling. The riders can drit on the track which is a sliding motion. When the rider is peddlig it causes the wheels to roll.

NICE!!! Although there is one thing that isn't correct, and maybe someone could add something on balanced and unbalanced forces?

The bikes would be unbalanced because they are always changing speed and direction.

in the picture of the two guys fighting you can see a lot of force,thrusting,air resistance,and vectors. in fighting you need to use a lot of force and thrust to knock your appoint out. there is air resistance in this picture too you can really see it but its there you would have seen it while the guys fist was just about to hit the other guy you see the air resistance slowed down his punch like if you stick your hand out of a moving car you can feel it moving just a little bit but if you lifted your arm up just a little bit your arm would slam into the side of the cars door window. you can see vectors in this picture because his fist has a direction and that was the other guys side. in meaning a vector has direction in it so you can see plenty of direction in his fist. another thing i can see is speed he needs speed and lots of it to hit his appoint as hard as he can so he can win the fight. 12/16/2013 11:38:23 am
The man who is throwing the punch us an unbalanced force the ref is an balanced force watching the hit take place. The bicycle list is accelerating to have a force greater than gravity.
