To determine which graph represents an object with negative acceleration, we need to understand how acceleration is represented on a graph.
Acceleration is the rate at which an object's velocity changes over time. When the velocity is decreasing, the object is experiencing negative acceleration. On a position-time graph, negative acceleration is represented by a decreasing slope, while on a velocity-time graph, negative acceleration is represented by a decreasing line or a line with a negative slope.
Since there is no image provided, I am unable to refer to the graphs directly. However, to identify the graph representing an object with negative acceleration, look for a decreasing slope or a line with a negative slope on a velocity-time graph (or a decreasing slope on a position-time graph).
To determine which graph represents an object with negative acceleration, we need to understand the concept of acceleration first.
Acceleration is the rate at which an object's velocity changes over time. It can be positive, negative, or zero.
If the velocity of an object is increasing, the acceleration is positive. If the object's velocity is decreasing, the acceleration is negative.
Now, let's analyze the given graphs (A, B, C, and D) and identify which one represents an object with negative acceleration.
Graph A: If the object is moving uniformly with a constant velocity, there is no acceleration, so this is not the graph we're looking for.
Graph B: If the object is moving with an increasing velocity, the acceleration is positive, so this is not the correct graph.
Graph C: If the object is moving with a decreasing velocity, the acceleration is negative. Therefore, this graph represents an object with negative acceleration.
Graph D: If the graph shows the object at rest (constant velocity of zero), there is no acceleration, so this is not the graph we're looking for.
Hence, Graph C represents an object with negative acceleration.
