Video #1 Please watch the video and answer the following questions: 82% Q1- What does constant velocity refer to? Constant velocity refers to the motion of the car. It maintains a constant velocity throughout its duration in terms of its direction and the distance covered over the time (m/s). The slope of the line (a straight line) does not change its angle or direction, so it is constant velocity. Q2- What was the velocity of the small car during the first part of the movement (moving away from the origin)? Was the speed negative? Or positive? The velocity of the car was going in a negative direction away from the origin (going left of the origin), going in a downward slope. The speed of the car was negative at -1.335 m/s. Q3- What was the velocity of the small car during the second part of movement (moving toward the origin)? Was the speed negative? Or positive? The velocity was positive with a slope of 0.5731 m/s. The speed of the car was also positive. Although car was going backwards, it had a positive slope indicating a positive velocity. Q4- What does that mean if the car has a negative velocity or positive velocity? Explain both. If the car has negative velocity it means it's going toward the negative direction (left away from the origin), and you can see this if the slope of the line is negative. If the car has positive velocity, it is going toward the right of the origin maintaining a positive slope trend. Q5- What are your comments on the first part of the car movement (moving away from the origin) according to the video data? Did the car have a constant velocity during this part? The movement of the car had a changing velocity in the first part, it had a positive acceleration, upward sloping graph, indicating it sped up, and the velocity was changing throughout the time intervals. Q6- What are your comments on the second part of the car movement (moving toward the origin) according to the video data? Did the car have a constant velocity during this part? Toward the end it hit the wall and went backward. With this, it would seem the car had a changing velocity separate from the first part, when having to switch directions. When looking at the video analysis it starts going backward toward the origin and has a negative acceleration of -0.1363 m/s/s, indicating it is slowing down. Therefore, for the velocity to be Q7- Write down the equations that describe the velocity and the position of the small car at any time. X=mt+b, m represents the slope, the velocity, the speed of the object Vx=mt+b, m represents the slope, the acceleration of the object over time. Why is the y position vs. time constant? The y position is constant due to the cars position in motion. The slope of the line remains constant as it moves away from the origin. The velocity at which the car is moving denotes the angle of the line.

The Change velocity resters to when ation is Constant Q2- What was the acceleration of the small car during the first part of the movement (moving away from the origin)? Was the acceleration negative? Or positive? The Car was moving with a Positive Kan can't be used to keep velocity, the accleration it Constant is negative as the Q3- What was the acceleration of the small car during the second part of the movement (moving toward the origin)? Was the acceleration negative? Or positive? The accleration is keep it the case will be Constant Positive because te for is 480 to Q4- What does that mean the car has a negative or positive acceleration? Explain both. A negative occleration is when the car is Slowing down, and positive acceration will be the Car Speeding up Q5- What are your comments on the first part of the car movement (moving away from the origin) according to the video data? Did the car have a constant velocity during this part? What Positive but it is Constant while Positive but it isn't about its acceleration? The velocity is the accleration is Q6- What are your comments on the second part of the car movement (moving away and then toward the origin) according to the video data? Did the car have a constant velocity during this part? What about its acceleration? The car has a Constant accleration with the on Positive and te becomes negative because the Parabola being X vs. t graph is used velocity is and te an upside turns oround and goes back Q-7 What is the turning point according to the video (case# 2)? te car The turning Point towords the is Origin When
