Motion: Units and Concepts

Motion Key Concepts

• Distance is the total length of the path traveled by an object.
• Displacement is the change in position of an object in a particular direction.
• Position is the location of an object relative to a reference point.
• Time is the duration during which motion occurs.
• Speed is how fast an object is moving, or the rate of change of distance with time.
• Velocity is the speed of an object in a specific direction.
• Acceleration is the rate of change of velocity with respect to time.

Types of Motion

• Uniform Motion is motion at a constant speed in a straight line.

Graphs

• Distance-Time Graph: shows how distance changes over time.
• Position-Time Graph: displays how position changes over time.
• Velocity-Time Graph: illustrates how velocity changes over time.

Calculations

• Calculate slopes of graphed lines to determine:
  • Speed (from distance-time graph)
  • Displacement (from position-time graph)
  • Acceleration (from velocity-time graph)

Equations

• Know and use equations for:
  • Time interval
  • Position
  • Displacement
  • Speed
  • Velocity
  • Acceleration

Word Problems

• Apply understanding of graphs and equations to solve problems involving motion scenarios.
