Document Summary
The study of physical quantities and the relationships amongst them. There needs to be a standardized unit that the community shares. Vectors tell you how much (magnitude) and direction (which way) Picture/graph. map/diagram: interpretation of slope of a graph and of area under a graph. All other physical quantities are derived because they are a combination of some of these 7. From point a to point b stretched out is the distance, but a straight line from point a to point b is the displacement. Total momentum before collision = total momentum after collision. Elastic - don"t stick together at all; kinetic energy is also conserved. Force times distance moved in the direction of the force. Unit = 1 joule; 1 j (1 n times 1 m) Work is equal to the change in kinetic energy. About how far you are from the center of earth (potential. Mechanical energy is kinetic plus potential energy.
