1- Speec Forms of energy - The two main types of energy are kinetic & potential Types Kinetic Potential Mechanical s Elastic Chemical Thermal Electrical) < Sound Radiant- Nuclear > -Gravitational Motion - Motion is when an imaginary line joining the object to the reference point changes in length or direction or both. Uniform motion - Uniform motion object is traveling at a constant rate in a straight line means an - Uniform motion is hard maintain Because its hard to maintain the term to. average speed is normally used.Average speed is uniform motion that involves · traveling a distance in a specific time. Average Speed Formula d Average Speed = DistanceTravel a V + V = E SOPope of a graph can tell you something about the motion of the object Slope-rise/run Crise is distance) (run is time) 2-Velocity Scalar & Vector - Scalar means how much - Vector means how much & direction Speed is a Scalar quantity Speed symbol = V Displacements a VectorDistancesym Distance is a Scalar Velocity Velocity & Displacement - Velocity has direction speed and Displacement is distance with direction - Identifying Vectors to The 2 methods - identify vectors are the cc-axis method and the navigator method - The x-axis method uses right left up , and down ,. - The navigator method uses north east, south and ,. west go 900 2700 9001888 go 2788 Noeator x-axis Formula's j velocity displacement E + = average 3-Acceleration Acceleration - Acceleration is the change in velocity during a specific time Formula in a ↑ acceleration Change = = a it ↑ Work- Force - Force is a push pull or on an Object measured in Newtons (N) - Forces can be gravity,friction etc. - An unbalanced force on an object can either speed it up or slow it down. Work - Work is done whenever a force moves an object through a distance Formula W Work = Force Distance x FD Conditions For Work There must be movement 3 There must be a force The force & distance the object travels in must be the same direction Energy - energy is the ability to work That means and work essentially the thing - same energy are. - E W =
