Student Exploration: 2D Collisions Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary​:​ center of mass, cons... ervation of energy, conservation of momentum, elasticity, kinetic energy, momentum, speed, vector, velocity Prior Knowledge Questions ​(Do these BEFORE using the Gizmo​.) Gizmo Warm-up Objects collide all the time, but often with very different results. Sometimes colliding objects will stick together. Other times, they will bounce off each other at an angle. What determines how objects will behave in a collision? You can use the ​2D Collisions​ Gizmo to find out. Note the arrows, or ​vectors​, on each puck. Click ​Play​ ( ). 1. How does the direction and length of its vector relate to the motion of a puck? 2. The ​velocity​ (speed and direction) of each puck is described by components in the ​i ​and ​j​ directions. The symbol for velocity is ​v​. (Vector quantities are shown in bold.) 3. The ​speed​ (​v​) of a puck is equal to the length of its velocity vector. To calculate the speed of a puck with a velocity of ​a​i ​+ ​b​j​, use the ​Pythagorean theorem​: Reproduction for educational use only.

Which component represents movement in the east-west direction? i comp. B. Which component represents movement in the north-south direction? j comp. Set the velocity of the blue puck to 12.00​i​ + 5.00​j​ m/s. What is its speed? v= [Show More]
