Question 1: which of the following graphs is traveling at a constant speed? graph e graph f graph g graph h question 2: which line represents the constant acceleration? a, b, and d a only c only b and d only question 3: the following displacement graph was created from a toy cart's travel around a small track connected to a computer for data graphing. which statement below is true based on the graph? line segment ab is showing the cart travelling at 10 m/s. line segment bc is showing acceleration as the cart is increasing its speed. line segment de is showing the cart is travelling at a constant rate. line segment cd is showing acceleration as the line has a straight increasing slope. question 4: study the two graphs. use your knowledge of speed and velocity to determine if they are representing the motion of the same object and why. no, the speed graph shows an object (1) at a steady speed, (2) slowing down, (3) stopping and rolling back. the velocity graph shows the object (1) speed up (2) slow down, and (3) stop completely. yes, the object moves (1) at a steady rate (2) speeds up (3) stops and then rolls back, slowing down. yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up. no, the speed graph shows an object (1) speeding up and then (2) slowing down. the velocity graph shows the object in (1) constant motion and then (2)stopping. (graphs are uploaded in order of the questions)

(1) At constant speed, the change in distance per time is constant, Graphs G represents constant speed

(2) graph B and D represents constant acceleration.

(3) The increase in speed over time indicates acceleration as the line has a straight increasing slope.

(4) yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up.

(1)

At constant speed, the change in distance per time is constant.

Graphs G represents constant speed

(2)

Constant acceleration occurs when the change in velocity is uniform over equal time interval.

graph A represents constant deceleration

graph B and D represents constant acceleration

(3)

The line segment CD represents increase in speed over time. The increase in speed over time indicates acceleration as the line has a straight increasing slope.

(4)

From the fourth graph, the object started at constant rate, slows down, stops and finally speeds up.

Thus, we can conclude that, yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up.

1. Graph G shows constant speed.

2. C is constant speed and A is deceleration. So the answer is B and D only.

3. AB distance is same so car is not traveling. CD car is at constant speed. DE car is decelerating. So the answer is Line segment BC is showing acceleration as the cart is increasing its speed.

4. Yes, the object moves (1) at a steady rate (2) slows down (3) stops and then rolls back, speeding up.
