Question

The following graph describes an aspect of an object's motion over a certain amount of time. What is being described by the graph? The object's velocity is increasing the object's velocity is decreasing The object's acceleration rate is decreasing The object's mass is decreasing Based on the following graph, how does the velocity of an object change from 1 second to 5 seconds? It increases It decreases It remains the same It Increases then decreases Based on the following graph, describe how the object is accelerating. The acceleration rate is increasing the acceleration rate is decreasing The object is not accelerating The acceleration rate is constantly changing How does the acceleration due to gravity change on Earth? The higher an object is, the higher the acceleration rate will be. The high an object is, the lower the acceleration rate will be. The acceleration rate increases the closer an object gets to the surface in freefall. The acceleration rate remains constant.

Explanation / Answer

12) as shown in the graph with time the velocity is decreasing,so the answer is b) the object's velocity is decreasing

13) since from t = 1 to t = 5 sec

accelaration is constant

i.e the velocity is increasing steadily

so the answer is a) it increases

14) As shown in the figure the velocity is constant which means that accelaration is constant

so the answer is c) The object is not accelarating

15) For any massive object ,the accelaration due to gravity is constant irrespective of mass and accelaration due to gravity = 0 m/s^2

so the answer is d) The accelaration rate remains constant
