1: Types of energy -- The types of energy are potential and kinetic energy. When something is not moving, it is potential energy. When something is moving, it is kinetic energy.
2: Energy in collisions -- The energy in a collision is mostly kinetic energy. When two or more things collide, the energy transfers from one to another.
3: Weight -- When something has weight, it means that the object has mass. If 2 things that have mass collide, because of the force, both objects will get pushed away.
My Vehicle -- The vehicle my team and I created, had bumpers . It had bumpers so when it crashed the bumpers would protect the car. The car also had a protection tire. The car had a protection tire so when the collision happened the tire would protect the egg.
