A gymnast performs an amazing flip! He lands on the floor and his feet put a force downwards on the floor. Newton’s Third Law reaction force is: (A)The weight of gravity on the gymnast
(B)The weight of gravity on the floor
(C)The force of the floor upwards on his feet
(D)The force of the floor downwards on his feet

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
