3Frame of reference Used to describe motion in reference to something. A fixed point
4Distance vs. Displacement Distance is the total path taken by an objectDisplacement measures the distance between starting and ending points
5Speed vs. VelocitySpeed describes how fast an object moves (called a scalar quantity)Velocity describes speed and direction (called a vector quantity)
6Speed and velocityFormula: distance/timeV=d/tUnits? ____
7Velocity PracticeFind the velocity in meters per second of a swimmer who swims 110 m toward the shore in 72 seconds.Find the velocity in meters per second of a baseball thrown 38 m from third base to first base in 1.7 sec.Calculate the distance in meters that a cyclist would travel in 5.00 hours at an average velocity of 12.0 km/h to the southwest.
8Daily Science pg. 4A car is traveling east for a distance of 890 meters. It will take the car 37 seconds to travel the distance. What is the cars velocity?A line of dominos is set up on a table. You push the first domino to make the rest fall. The dominos fall at a velocity of 0.2 m/s down the table. It takes 15 seconds for the last domino to fall. How long was the domino line?If you run with an average velocity of 2 m/s toward a goal, a total distance of 400 m, how long would it take you?
9Resultant velocity pg.1Velocities can be combined to describe the resultant velocity.Ex. You are riding a bus that is traveling 15 m/s east. You stand up and walk toward the back of the bus (now walking east) at 1 m/s. Are you still traveling at the same speed?To find the resulting velocity, just add the velocities together.
10Instantaneous Speed The speed at a given point. Car speedometers measure the speed at a given point.
