Blog Analysis

a. Me and Kristen's car began to move becuase of Newton's first law of motion. It would have stayed at rest unless an outside force acted on it. Example: The lighter the balloon was, the faster it would accelerate. The more momentum is caused by more mass. So, if our car was heavy, which it wasn't, it would have kept going becuase of momentum.

b. The action force was the balloon pushing out air. The reaction force was the air pushing on the balloon.

c. The first object is the car, acting on the ground. The second objectis the balloon, acting on the car.

d. The wheels create rolling friction on the ground.

e. Newton's third law relates to the first becuase if the action force causes it to go, it will keep going and if the reaction force causes it to stop, it will stay stopped unless acted on by an unblanced force.

f. The three frictions are rolling, sliding, and fluid.

g. This affects the start (which is fluid friction) becuase the air in the balloon acts on the tip of balloon to come out, causing friction. Rolling frictiontakes place while the car is rolling, becuas the wheels roll on the ground causing friction becuase the wheels come to a stop and they just  slide on the steels rods (holding the wheels) creating friction.
