<span>So what happens when there is more than one force? I like to think of net force as if two people were pulling on ropes attached to a big crate. If they pull the crate in the same direction, the crate will accelerate twice as quickly.

If one person pulls northwards and the other pulls eastwards, the crate will move to the north-east.
