This graph is just plain wrong. How can Tom be in two places at once!!!!
D
500
Energy in heat.
What is thermal energy?
500
The ability of capacity to do work.
What is Energy?
500
Energy cannot be created or destroyed, but it can be transformed.
What is the Law of Conservation of Energy?
500
Why is it harder to stop a four-person bobsled than a three-person bobsled?
A four-person bobsled has an extra person so it has more mass than the three-person bobsled. So the more mass the more kinetic energy the bobsled has in the race. The more kinetic energy the faster it is moving thus the harder to get stopped.
