Question

This graph illustrates the change in velocity over time of an object. What conclusion can you draw about the force acting on the object?
A)
The force is balanced.


B)
The force is unbalanced, but generally consistent over time.


C)
The force is unbalanced, and generally increasing over time.


D)
The force is unbalanced, but it is impossible to determine whether it is changing over time.

Answer 1

C) The force is unbalanced, and generally increasing over time.
Notice how the lines are becoming more steep as it goes left-->right, meaning the slope of each interval of time is increasing. And an increase in velocity over time is the definition of positive acceleration.
Therefore this force continues to increase the velocity over time.
