Forces and Energy

Potential vs. Kinetic Energy How are potential and kinetic energy related? When one increases, what happens to the other?

Potential vs. Kinetic Energy In your notebook, draw your prediction of what a graph would look like of a rollercoaster starting at the peak of a large dip X-axis: object’s movement/distance traveled Y-axis: amount of energy

Potential vs. Kinetic Energy

Colliding Objects Car 1 is at rest – Car 2 collides into the back of car 1 What happens to the kinetic energy of car 2? What about car 1? What is the motion of the cars after the collision? * think about bumper cars * What if their masses are equal? What if they aren’t?

Newton’s 3rd Law of Motion When 2 objects collide, kinetic energy is transferred from one object to another Newton’s third law is the “action/reaction” law For every action, there’s an equal and opposite reaction

Rollercoaster Energy How are kinetic and potential energy related with regards to a rollercoaster? How much energy exists in the system at the beginning of a rollercoaster ride versus the end of a rollercoaster ride? Let’s find out…

Let’s Go Back to Our Essential Question “Could an asteroid impact with Earth cause a mass extinction?” Here’s a prediction of what it may look like
