Physics I Assignment 07: Move the dot straight from the left of the screen to the right, taking a few seconds to complete the motion. Which vector represents the velocity, and which represents the acceleration? When is the acceleration vector longest? When is the velocity vector longest? When do the vectors have the same direction, and when are their directions opposite?Repeat but move the dot as quickly as possible from left to right. Describe the behaviors of the two vectors.
Now start in the upper left-hand corner, moving at first to the right, but as you continue to move to the right gradually begin arcing downwards so that you follow a graceful (?) curve from upper right to lower left. Describe the behavior of the velocity and acceleration vectors.
Now move the dot around a circular path. Follow a slow circular path, then try to double your speed along the same path. How does the direction of the acceleration vector compare with that of the velocity vector? If you double the speed, then what happens to the magnitudes of the velocity vector and the acceleration vector?
Submit a copy of your results and insights using the Submit Work Form, with title 'Ladybug Motion'.
The green vector represents the velocity and the blue vector represents acceleration. The acceleration vector is the longest when the change in velocity is the greatest. The velocity vector is the longest when the ball is moving the fastest. The vectors have the same direction when the object is accelerating(moving faster) and they have opposite directions when the ball is decelerating (moving slower).
When moving the dot as quickly as possible, the velocity and acceleration vectors both become longer.
When I move the ball in a graceful curve downward, the velocity vector is small and I cannot see the acceleration vector.
When moving in a slow circle, the velocity vector is always changing to point in the direction of the circle, and I cannot see the acceleration vector. When I double the speed, the velocity vector gets larger and the acceleration vector becomes visible and it constantly pointing towards the inside of the circle.
