This time, we had created a projectile which can shoot the farthest. We got materials and we need to build it. My group was won the competition because we had shoot the farthest. After that we gather together to talk about why some projectile can shoot far and some not and also about the friction around it. But before we could make the projectile, we have to read about the instruction and learning about velocity, gravity, trajectory and parabola. Here is what I got in my notebook with my team
- Velocity: Speed that moves in particular direction
- Gravity: When we throw the ball, the gravity pull downward to let the ball rest on the ground
- Trajectory: The trajectory is a path for the projectile launcher to travel in.
- Parabola: When you throw the ball in less force, it becomes curve shape. The curve shape called “parabola” which observed in geometric equations (travel in a horizontal line and vertical line)
We also had created a MIND MAP for the projectile launcher and you can see the picture below about what I wrote in the book.
