Im still confused on how to describe motion. Like how do I describe it using velocity, speed, distance,etc. The question that I need to answer is:
How would you describe the motion of a vehicle or groups of vehicles using (CER)?
Please help
To describe the motion of a vehicle or groups of vehicles using the CER (Claim-Evidence-Reasoning) framework, you can follow these steps:
1. Claim: Start by making a claim or stating your overall observation about the motion of the vehicle(s). For example, you might claim that the vehicle(s) are moving at a constant speed.
2. Evidence: Support your claim with specific evidence. To describe motion, you can utilize different concepts such as velocity, speed, and distance. Here's how you can use each of these concepts to gather evidence:
a) Velocity: Velocity is a vector quantity that considers both the speed and direction of an object's motion. You can measure the velocity of a vehicle(s) by analyzing its change in position with respect to time. For example, if you calculate that the vehicle(s) are moving at a constant velocity of 60 km/h towards the west, you can provide this as evidence.
b) Speed: Speed is a scalar quantity that measures how fast an object is moving. It only considers the magnitude of the motion, disregarding its direction. To determine the speed of the vehicle(s), you can divide the total distance covered by the time taken. For instance, if you find that the vehicle(s) traveled 100 kilometers in 2 hours, you can mention this value as evidence.
c) Distance: Distance is a scalar quantity that represents the total path length covered by an object without considering its direction. You can measure the distance traveled by the vehicle(s) by summing up the lengths of all the individual segments of the journey. If you determine that the vehicle(s) covered a distance of 300 kilometers, you can present this value as evidence.
Remember, the evidence you provide in the CER framework should be accurate, relevant, and based on reliable data or measurements.
3. Reasoning: Finally, support your claim and evidence with reasoning. Explain how the evidence you provided confirms or supports your claim. In this case, you can reason that the consistent velocity, speed, and distance measurements indicate that the vehicle(s) are moving at a constant speed, which suggests a stable and predictable motion.
By using the CER framework, you can effectively describe the motion of a vehicle or groups of vehicles, explain how you obtain the information, and give a logical reasoning for your claim based on evidence.
