High Impact

Push:
Push is the force we use when we are trying to push something open. Push, the force is when your using your energy to push something away from you. e.g when you open the door for someone that's when you use the force push! Without the force push in this world average humans couldn't move anything.


Gravity: 
Gravity is what pulled our marble run down into the centre of the Earth! e.g our marble run when from a high gravity to low gravity which meant our marble was rolling downwards towards the middle of the Earth! That helped us with speed and length.



Kinetic Energy: 
This sort of force is when it collects and gathers all of its energy while the marble is rolling down towards the bottom. It gathers a lot of force when it is going around bends or swirls because unlike straight pieces those S shaped ones should have more energy to collect only because its not as fast as a straight piece. 

Accelerate:
Accelerate is a force that means what pieces of your marble run made your marble move faster. By adding lots of pieces to our marble run it made the marble speed up, when it collected that energy rolling down.
