The Work-Energy Principle is an important idea in science. It tells us that the work done on an object is equal to the change in its kinetic energy.
But, when we apply this idea to roller coasters, things can get tricky because of a few reasons:
Friction: This is when energy is lost as heat. It makes figuring things out harder.
Height Changes: To find potential energy, we need to measure heights accurately. The formula for this is , where "m" is mass, "g" is gravity, and "h" is height.
To make things easier, here are some things we can do:
Think About Friction: We can use a friction number to guess how much energy is lost.
Measure Heights Carefully: Using tools can help us get the right height so our potential energy calculations are correct.
By solving these problems, we can better understand how roller coasters work!
