Answer:
The slope of a position-time graph represents an object’s velocity.
Explanation:
In a position-time graph, the values on the x-axis represent the time, while the values on the y-axis represent the position of the object.
Velocity is defined as the ratio between the displacement of an object and the time taken:
However, we can see that this definition corresponds to the slope of the curve in a position-time graph. In fact:
, the displacement, corresponds to the difference in position, so the difference between the values on the y-axis:
, the time interval, corresponds to the difference in times, so the difference between the values on the x-axis:
So, the velocity is
which corresponds to the slope of the curve.
Answer:
E) The average velocity of the car is 90.0 miles per hour in the direction of motion.
Explanation:
Given;
distance covered by the car, d = 90 miles
time taken, t = 60 minutes = 1 hour
The average velocity of the car is given by change in displacement per change in time;
V = Δd / Δt
Therefore, the average velocity of the car is 90.0 miles per hour in the direction of motion.
