Answer 1

The characteristic that is constant for the car as it travels around the roundabout is speed.

However, it is important to note that while the speed remains constant, the velocity (which includes both speed and direction) is constantly changing because the car is changing direction as it moves around the roundabout.

If the question is about which characteristic remains the same in terms of numerical value, then "speed" would be the most accurate answer.

change in direction

Answer 3

On a position–time graph, the value of the slope indicates the velocity of the object.

The slope represents the rate of change of position with respect to time. A steeper slope indicates a higher velocity, while a slope of zero indicates that the object is at rest.

Only object C has a constant velocity.
Only object C has a constant velocity.

Only object D has a constant velocity.
Only object D has a constant velocity.

Neither object has a constant velocity.
Neither object has a constant velocity.

Both objects have a constant velocity.

Answer 5

To determine whether either object has a constant velocity, we would typically analyze the position–time graphs or data for both objects.

• If an object's position changes at a constant rate over time, then it has a constant velocity.
• If the position changes at varying rates, then the velocity is not constant.

Without specific details or graphs for objects C and D, I cannot definitively answer whether either object has a constant velocity. You would need to assess the graphs or data for a consistent slope (for constant velocity) or changing slopes (for varying velocity).

If you can provide the graphs or describe the motion of objects C and D, I would be happy to help you analyze their velocities!

Both objects have a constant velocity.

Answer 7

To accurately determine if either object has a constant velocity, we would need information regarding the position-time graphs or the specific descriptions of the motion for objects C and D.

However, based on the response options provided, here’s how you could approach the problem:

1. Constant Velocity: If the position changes uniformly over time (i.e., the graph is a straight line), the object has a constant velocity.
2. Variable Velocity: If the position changes at different rates over time (i.e., the graph is curved or has varying slopes), the object does not have a constant velocity.

You need to determine the nature of the graphs or descriptions of objects C and D. Here is a simplified breakdown based on the response options you provided:

• If the graphs or data for Object C show a straight line, then only Object C has a constant velocity.
• If the graphs or data for Object D show a straight line, then only Object D has a constant velocity.
• If both graphs show straight lines, then both objects have a constant velocity.
• If both graphs are not straight lines or show varying slopes, then neither object has a constant velocity.

With your choices:

• Select the appropriate response based on the actual characteristics of objects C and D.

If you provide further details about the objects, I can help you interpret them!
