What is the difference between distance and displacement?
What is the difference between distance and displacement?
- Distance is the speed of an object, while displacement is the velocity of an object.
- Distance is the change in position, while displacement is the total length of the path traveled.
- Distance is the total length of the path traveled, while displacement is the change in position. (correct)
- Distance is the acceleration of an object, while displacement is the deceleration of an object.

Study Notes
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.
