PS.10 The student will investigate and understand scientific principles and technological applications of work, force, and motion. Key concepts include… a. Speed, velocity and acceleration
Title: Linear Motion
Main Concepts: force, velocity, speed, and acceleration
UKDs: As a result of this lesson students will:
Forces affect the speed of an object Acceleration relates to speed
Velocity and acceleration are not the same thing Know …
The definition of speed, velocity and acceleration Velocity includes speed and direction That mass affects acceleration
How to explore motion graphically Be able to…
Calculate the velocity of an object Graphically draw the relationship between speed and direction Graphically draw the relationship between velocity and direction Describe motion in writing
Recreate a graph describing motion
How do we move from place to place? Students will most likely say by driving a car, but this lesson will focuses on how the forces helping the vehicle to move. I will ask questions about something that moves more simply, such as an cheetah. What does it mean for a cheetah to run 70 miles per hour? I will show the students a short clip of a cheetah running. The cheetah has an obvious direction and speed. But we are curious as to how the cheetah is creating the speed and how that speed is slowed down when the cheetah needs to stop. The lab will investigate further into how the relationship between speed and direction can be represented graphically.
The students will complete the...
