Types of energy
The 3 main types of energy are kinetic energy, potential energy, and gravitational energy. Potential energy is when energy is stored up in an object, while kinetic energy is energy in motion. Gravitational energy is when gravity can effect collisions and other energy related thing. There is also other types of energy, such as heat, sound, etc.
Energy in a collision
When 2 cars collide, the energy from one car transfers to the other car. Both car's kinetic energy cause a big wreck. We tested 2 cars colliding in class, both cars hit and it caused both of them to spin out of control.
Weight affecting energy
When a car has more weight, the car has more kinetic energy, so it will go faster than the other car. Weight can also effect a car because it will make the car bounce back and flip over. We tested 2 cars colliding in class, one car was heavier, so when it collided, the car with more weight flipped over, while the car with much less weight bounced back and rolled back really far.
