Linear+Motion

> > ex. The car was moving at 20 m/s N at 6 seconds after it started moving. Eli Example: Two children of different weights attempting to balance a see-saw by along the fulcrum (board of the see-saw)
 * Important Topics **
 * definitions for: scalar quantity, average speed, vector quantity, position, displacement, velocity, average velocity, instantaneous velocity, instantaneous speed
 * the slope of the line on a position-time graph indicates velocity
 * the area under the line on a position-time graph indicates the velocity
 * average acceleration is the average rate of change of velocity
 * instantaneous acceleration is the acceleration at a particular instant
 * the slope of a line on a velocity-time graph indicates the acceleration
 * the area under the line on an acceleration-time graph indicates the change in velocity
 * there are five variables involved in the mathematical analysis of motion with constant acceleration and there are five equations, each of which has four of the five variables
 * Define and Provide a Real World Example:**
 * 1) ** scalar quantity ** - a scalar quantity is a value that is expressed only with a single number value. Energy and temperature are scalar quantities.
 * 1) average speed
 * 2) vector quantity
 * 3) position
 * 4) displacement
 * 1) ** velocity ** - A vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion. Ex. A marathon runner was running at 15 km/h [S].
 * 1) ** Average Velocity ** - It is the net distance traveled divided by time. Ex. When a car moves 50 km in 2 hours, the average velocity is 25 km/h
 * 1) ** Instantaneous Velocity ** - The velocity of an object at any given time. If its movement was graphed on a Velocity over time graph, it's instantaneous velocity would be a single point on the graph.
 * 1) ** Instantaneous Speed ** - The speed of an object at any particular time. Example. A radar gun taking the speed of a speeding car.
 * 1) ** Kinematics ** - The study of motion without the effects of forces. Example: Visitors to an amusement park; some people may walk at a constant speed in a straight line. Others, descending on a vertical drop ride, plummet at a very high speed before slowing down and stopping.
 * 1) ** Dynamics ** --In physics, dynamics is a branch of mechanics which observes and measures the forces that change or produce motions in objects. ex. If Captain Falcon were to "Falcon Kick" you ---Isaac
 * 1) ** Statics ** (Candice!)
 * "Static" means stationary or at rest (static equilibrium).
 * Follows Newton's 1st law of motion "Objects at rest will stay at rest, objects in motion will stay in motion"
 * Provided that all forces acting on the object have an Fnet of 0, the object will be in static equilibrium.
