Which of the position-time graph represents negative acceleration?

A curved position-time graph indicates non-uniform motion. A velocity-time graph with a positive slope indicates an object is accelerating. A velocity-time graph with a negative slope indicates an object is negatively accelerating. A velocity-time graph with a flat line (slope of zero) indicates uniform motion.

What does negative acceleration look like on a graph?

If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration). The acceleration-time graph shows a horizontal line in the negative region of the graph (meaning a negative acceleration).

What does it mean when a position-time graph is negative?

In position and time graphs, the slope of line indicates the velocity. Therefore negative slope of a position-time graph actually indicates negative velocity. Negative velocity is defined as the velocity of the object moving in an opposite direction.

How do you calculate negative acceleration?

Negative acceleration is calculated by dividing the final velocity minus the initial velocity by the amount of time taken by the body to reduce the velocity. If the velocity is in the positive direction, negative acceleration indicates that the object is slowing down.

What indicates negative acceleration?

According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus, this object has a negative acceleration. When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, this object also has a negative acceleration.

How do you find acceleration on a position-time graph?

Method 1: Using the position data (distance versus time graph). So, 1/2 a = 1.412 so then a is 2*1.412 =2.824 – thus we have obtained the acceleration from the position graph.
