Think of Einstein’s theory of general relativity. If a wide receiver making a catch collides in midair with the defender, the defenders often fair little better in these situations because they tend to run a little larger than receivers. But it is not a matter of force. Newton’s third law of motion (“to every action there is an equal and opposite reaction / the mutual actions of two bodies upon eachother are always equal and directed to contrary parts”) implies that this issue has to do with momentum, the product of mass and velocity. A force between two objects is an interaction that changes momentum. If the momentum of one increases, the momentum of the other will decrease by a substantial amount. All that is needed to be thought about is is the momentum right before the two come into contact and the momentum right after they stop interacting.
Assuming that you are asking for help identifying the keys, the items are asking for you to draw either a flat or sharp sign in front of the note (depending on the question) and to identify what letter note it represents. The letter notes of the treble clef (starting from line 1, the bottom line) are E, F, G, A, B, C, D, E, and F. The line acronym is Every Good Boy Does Fine, and the space acronym is FACE. The letter notes of the bass clef (starting from line 1, the bottom line) are G, A, B, C, D, E, F, G, and A. The line acronym is Good Boys Do Fine Always, and the space acronym is All Cows Eat Grass. For example, on the second note of question three, you would draw a flat sign in front of the note, and write its letter note, A, on the line below it. If you would like the answers directly, please don't hesitate to ask.
