The position-times graph of an object is a straight line with a positive slope.

Question

The position-times graph of an object is a straight line with a positive slope. The object has: a. constant displacement b. steadily increasing acceleration c. steadily decreasing acceleration d. constant velocity e. steadily increasing velocity Which of the following five coordinate versus time graphs represents the motion of an object whose speed is increasing? a. I b. II c. III d. IV e. V You applied a force (a push or a pull) on an object, and the object moved from one point to another. For the movement of the object a. the direction of the force is important but the magnitude of the force is not. b. the magnitude of the force is important but the direction of the force is not c. both the direction and magnitude of the force is important d. both the direction and magnitude of the force are not important e. More information is required to answer this question.

Explanation / Answer

5. If the slope of position time graph is positve and if it is straight line, then it represent the constant velocity. Hence option d.

6. First graph shows the increasing velocity, as the x coordinate increasing at the higher rate than that of time.

7. Both the direction and the magnitude are imprtant.
