Document Summary
Things that can be measured in the scientific sense of the word measurement. Vector quantities- have magnitude and direction picture/graph/map/diagram-interpretation of a slope of a graph and of area under a graph. Description- the distance covered per amount of travel time. Becomes 25 miles/hour x (1. 6km/1 mile)=40 km/hr. Xxxxx slope and math in written notes xxxxxx. Acceleration- is change in velocity divided by the time it takes for velocity to change. Experiment is superior to logic in uncovering natural laws. Long time after galileo proved this wrong with experimentation. Does a force keep the cannonball moving after it leaves the cannon- A force does not keep it moving after it leaves the cannon. Dynamic equilibrium- moving with a constant speed in a constant direction. Galileo"s experiments showed how things resist change. Things at rest will stay at r4est forever. You throw a ball behind you from chest level in front of you.
