Roosevelt High School CP Physical Science Unit 9 Net Force and Motion Graphs Name_____________________ Period___ Date____/____/___ Relating Fnet to Position-Time Graphs and Velocity-Time Graphs velocity position Rest ! ! !! ! velocity velocity Decreasing Speed, Negative Direction velocity ! velocity ! Increasing Speed, Negative Direction position Decreasing Speed, Positive Direction ! Constant Speed, Negative Direction position ! ! velocity position Increasing Speed, Positive Direction position ! position ! velocity position Constant Speed, Positive Direction In order to construct a graph for a motion scenario, we need to define the positive direction. ! For the rest of this unit, up is the positive direction for the vertical component. ! For the rest of this unit, right is the positive direction for the horizontal component. Roosevelt High School CP Physical Science Unit 9 Net Force and Motion Graphs Name_____________________ Period___ Date____/____/___ For each of the following, construct a system schema, free body diagram, position vs time graph, and velocity vs time graph. velocity position 1. A disco ball hangs on a cord from the ceiling. velocity position 2. The cord in number one breaks. Analyze the disco ball after it breaks. velocity position 3. A car heading left at a constant speed slams on the breaks when a basketball rolls out into the street. position velocity position velocity 4. A hot air balloon is tethered to the ground as the owner prepares for take off. 5. The hot air balloon is released and begins its ascent.
