Question

Which of the following best describes the motion of the object in this p-t graph? please answer quickly i'm giving 40 points.

The object is accelerating.
The object is decelerating.
The object has positive velocity.
The object is moving to the left.

Answer 1

Explanation:

A position time graph gives the velocity of an object. Its slope gives the velocity of an object.

In the given figure, the distance covered by an object decreases with respect to time. It means the speed decreases uniformly. So, the object is decelerating. Hence, the correct option is (b).

Answer 2

Answer:

The object has positive velocity

Explanation:

The steeper the slope, the greater the velocity. For example, an object moving 50 m/s, east, will have a steeper slope than an object moving 25 m/s, east. The shape of the line also describes the object's motion. A straight line indicates an object with no acceleration. The object is moving at a constant velocity. A curved line indicates an object with a changing velocity. In other words, a curved line indicates acceleration. A completely horizontal line represents an object with zero velocity. The object is not moving.
