Name: Daisha Crawford Date: 1/18/2024 Lab 01 – Velocity and Acceleration Q1. Which color represents velocity? Answer: The color that represents velocity is blue Q2. Which color represents acceleration? Answer: The color that represents acceleration is green Q3. Is the red ball speeding up or slowing down when the velocity and acceleration vectors are pointing in the same direction? Answer: The red ball is speeding up when the velocity and acceleration vectors are pointing in the same direction Q4. Is the red ball speeding up or slowing down when the velocity and acceleration vectors are pointing in opposite directions? Answer: The red ball is slowing down when the velocity and acceleration vectors are pointing in opposite directions Q5. When you drag the red ball across the screen in any direction, which vector shows up first? What does this mean in terms of the motion of the ball? Answer: When you drag the red ball across the screen in any direction, the vector that shows up first is velocity. What this means in terms of the motion of the ball is that both speed and direction would have to change in order for it to have acceleration showing up first. Q6. In uniform circular motion, in which direction is the velocity vector pointing? Answer: In uniform circular motion, the direction the velocity vector is pointing is to the center of the ball. Q7. In uniform circular motion, in which direction is the acceleration vector pointing? Answer: In uniform circular motion, the direction the acceleration vector is pointing is right then left. Wherever the ball goes. Q8: What is another example of a two-body system that this circular motion could represent?
Answer: An example of a two body system that this circular motion could represent is the sun and the planets
