How do you know when a chemical equation is balanced?
The amount of atoms of each element on both sides of the equation are equal; the forces need to cancel each other out
Question: If each arrow is an amount of force, how would we be able to tell if the forces were balanced?
Both sides would be the same number
If anything is moving, no matter how small a distance, the forces are unbalanced.
The object will move in the direction of the greater force
If a GMS football player and a NFL football player tried to tackle one another, who would be able to move who?
The NFL player applies the greater force. Therefore, the GMS player would move in the direction he was pushed.
Math Formula: Speed = distance
Fractions mean division
If you know 2 of these, you can solve
for the third!
