Aim: How do we use the kinematics formulas? Do Now: What is the difference between average velocity and instantaneous velocity? Quiz Tomorrow.

Speed & Velocity. Speed Anything that is in motion has speed. Speed is a scalar quantity—a measurement that does not include direction.

Speed, Velocity & Acceleration. Speed (s) – rate at which an object is moving Does not depend on direction speed = distance ÷ time (s = d/t) Constant.

Physics of Motion Poster Speed VOCAB 1. Motion is a change in position VOCAB 2. Motion is measured by finding the distance something has moved or an objects displacement Speed : is the distance an object travels over time Math Formula : S= d/t Example: A car drives 100 meters in 5 seconds what is its speed VOCAB: Distance: How far an object has moved Displacement: How far from a starting point(reference point) an object is VOCAB D= 100 meters T= 5 seconds S= 100/5 = 20 m/s METRIC UNITS Distance: Kilometers or meter METRIC UNITS Speed(s): Meters(m)/ second(s) Acceleration VOCAB Velocity: Speed in a given direction VOCAB Acceleration : Any Change in velocity Example of Speed: The rocket flew at a speed of 1000 meter/sec Example of Velocity: The rocket flew at a velocity of 1000 m/s towards the Northeast Three Types of Acceleration Speed Up ( positive acceleration) Slow Down (negative acceleration) Change direction Math Formula Accleration= Final Velocity- Initial Velocity/time A= Vf-Vi/t Example: A car drives goes from a speed of 0 m/s to 200 m/s in 10 seconds. What is the cars acceleration a=Vf –Vi/ t - 200-0/ 10 = 20 meters per second per second METRIC UNITS Velocity(V): Meters/ second METRIC UNITS acceleration(a): meters/ second/second
