Conce An object moves back and forth, as shown In the position-time graph below. 3 8 time 7 Which of the following statements are correct/incorrect? incorrect The velocity is zero at point 2. At points 1 and 3 the object is on the positive side of the origin. correct At point 3 the velocity is positive. incorrect incorrect CAt points 1 and 7 the velocities are about the same. incorrect At points 2 and 6 the object is the same distance from the origin. incorrect At point the object is farther from the origin than at any other numbered point. The velocity is negative at all of points 5, 6 and 7. Don't confuse position with velocity. Velocity is the SLOPE of the position-time graph. incorrect Submit Answer Incorrect. Tries 1/2 Previous Tries position

Answer 1

Which of the following statements are correct/incorrect?

(i) The velocity is zero at point 2.

$\Rightarrow$ Incorrect

(ii) At points 1 and 3, the object is on the positive side of the origin.

$\Rightarrow$ Correct

(iii) At point 3, the velocity is positive.

$\Rightarrow$ Correct

(iv) At points 1 and 7, the velocities are about the same.

$\Rightarrow$ Incorrect

(v) At points 2 and 6, the object is the same distance from the origin.

$\Rightarrow$ Correct

(vi) At point 8, the object is farther from the origin than at any other numbered point.

$\Rightarrow$ Correct

(vii) The velocity is negative at all points 5, 6 and 7.

$\Rightarrow$ Correct
