Question

position - time graph
when time increases, what happens to the distance?
describe the object’s motion.
what is the velocity of the object?

Explanation:

Step1: Observe graph trend

Position decreases as time increases.

Step2: Analyze motion from graph

Straight line with negative slope → constant velocity downward.

Step3: Select points for velocity

(t₁=0s, x₁=20m), (t₂=10s, x₂=0m)

Step4: Calculate velocity (slope)

v = (x₂ - x₁)/(t₂ - t₁) = (0-20)/(10-0) = -2 m/s

Answer:

When time increases, the distance decreases.
The object is moving with constant velocity in the negative direction (decreasing position).
The velocity of the object is -2 m/s.
