Momentum

"Wait, so, explain this to me one more time."

Mike sighed and pointed at the rock they were standing in front of. Perhaps rock was the wrong word - boulder might have been more accurate, given that the two of them could easily both sit atop it. They had rolled it towards the edge of a cliff, stopping just moments before it would have began to roll down the hill. "The magic uncle taught us?" he asked his brother. Joe nodded. "About stopping an object's time?" Another nod. "So we're going to freeze this rock, hit it a bunch so it builds momentum, and then before the spell breaks we're going to jump up on it and ride it."

"Are you sure that that's safe, though? That seems like a pretty good way to hurt ourselves."

"Look, Joe, all we have to do is jump off before it hits the ground. We've already learned a soft landing spell, and we know that that works. This could be the next great way to travel. We could create an entire business off of this! Shooting people great distances and giving them a soft landing."

"As far as I know, soft landing only helps to cease vertical momentum, Mike," Joe said, concern still evident on his face. "And with something like this, the bigger concern is going to be horizontal momentum. Even if we do cast soft landing and don't hit the ground hard, we'll still be carried forward and stumble into the ground and go tumbling. We can't even really predict where we're going to land. We could land in the middle of a lake and be unable to get to the shore safely."

Mike sighed again and rested one hand on the boulder. "You're worrying too much about this, Joe. We're wizards. More than that, we're wizard scientists. Isn't this what we said we were going to do? To try new things with our magic, and see what kinds of advancements we can make?"

"Well, yeah, but I wasn't really anticipating hurting myself in the process. I was thinking more along the lines of combining spells and such..."

"No pain, no gain, right?"

"I really don't think this is how that phrase is supposed to be used."
