300
An object with more ________ will need a stronger magnetic force to pick it up.
What is Mass?
300
Which height of slope will allow the truck to travel the fastest? (3m, 7m, or 10m) Explain. [2]
What is ...
14 M high, because it is steeper and will allow the truck to have more more kinetic energy.
