Study Notes
Reference Points in Motion
- Reference point for Tyler's trip is Atlanta, establishing the starting point for measuring distance.
- The diver likely used the ocean surface as a reference point to describe the squid's position.
Velocity and Speed
- The x-axis of a velocity graph is labeled "Time," while the y-axis is labeled "Velocity."
- Slope of the position vs time graph is used to calculate an object's velocity.
- Displacement must be described with both measurement and direction.
Acceleration
- Positive acceleration occurs when an object increases its speed.
- Distinctions in acceleration can be clarified by comparing velocities over time; Finley has the least, followed by Xander, then Max with the most.
Travel Time and Speed Calculations
- Koto's travel time, given her velocity of 4.5 m/s, is calculated to be 18.5 minutes based on her travel distance.
- Kai's round trip covers 200 meters in 200 seconds, yielding a speed of 2 m/s, while his velocity is 0 since he returns to his starting point.
Motion Analysis via Graphs
- Carla's velocity vs. time graph indicates she slowed down initially, stopped, and then accelerated again, illustrating changes in motion dynamics throughout her trip.
Key Concepts in Motion
- Understanding motion involves concepts of reference points, speed, velocity, acceleration, and displacement.
- Both speed and velocity are essential for analyzing an object's movement, but they differ in that velocity includes direction.
