Question
The graph below shows the velocity of an object of mass 1 g. Each line on the time axis represents 3 s and each line on the velocity axis represents 1 m/s. Which of the following statements, describing the graph below are true? (If A and E are true, and the others are not, enter TFFFT).
A) In section C, the force is constant and non-zero.
B) In section C, the force is negative.
C) In section D, the displacement is negative.
D) In section A, the force acts in the direction of the velocity
E) In section D, the force changes sign.

In section A, the force acts in the direction of the velocity In section D, the force changes sign.Explanation / Answer
TFFTT
1. rate of change of v is constant.. so acceleration is constant , so forece is contant.
2.speed is incresing , so force is on positive direction
3. Displacement is positive beause the body is always moving forward and not going back at any point of time
4.True
5. true bacause speed first increases and then decreases. So force first increses and then decreases to negative direction
