Understanding the Constant Velocity Model
The constant velocity model is a fundamental concept in physics that describes the motion of an object moving at a uniform speed in a straight line. This model simplifies many aspects of motion and is critical in helping students understand more complex topics in kinematics and dynamics.
Key Concepts
1. Velocity: Velocity is defined as the rate of change of displacement over time. It is a vector quantity, which means it has both magnitude and direction.
- Example: A car moving east at 60 km/h has a velocity of 60 km/h east.
2. Displacement: Displacement refers to the change in position of an object and is also a vector quantity. It is the shortest distance from the initial to the final position.
- Example: If a car travels from point A (0 km) to point B (10 km) directly east, the displacement is 10 km east.
3. Time: Time is a scalar quantity that measures the duration of an event or motion. In the context of constant velocity, it helps calculate how long an object takes to travel a certain distance.
Equations of Motion
In the constant velocity model, the fundamental equation that relates these concepts is:
\[ v = \frac{d}{t} \]
Where:
- \( v \) = velocity
- \( d \) = displacement
- \( t \) = time
This equation can be rearranged to find displacement and time:
- Displacement:
\[ d = v \times t \]
- Time:
\[ t = \frac{d}{v} \]
Understanding and manipulating these equations is crucial for solving problems related to constant velocity.

Types of Problems in Worksheet 4
1. Calculation Problems:
- Example: A cyclist travels 150 meters east in 30 seconds. What is their velocity?
- Solution:
- \( v = \frac{d}{t} = \frac{150 \text{ m}}{30 \text{ s}} = 5 \text{ m/s} \) east.
2. Word Problems:
- Example: If a train moves at a constant velocity of 80 km/h for 2 hours, how far does it travel?
- Solution:
- \( d = v \times t = 80 \text{ km/h} \times 2 \text{ h} = 160 \text{ km} \).
3. Graph Interpretation:
- Students may be provided with distance-time graphs and asked to derive velocity or determine the distance traveled over a specific time interval.
