**Kinetic and Potential Energy**Miss Friend**What describes energy that is stored due to the height of an**object from the ground?**A roller coaster at the top of a hill is an example of which**type of energy?**ME = KE + PE**Chase pushes a toy car down a hill. After 5 seconds, the car has a kinetic energy of 100 J and a gravitational potential energy of 20 J. What is the car’s mechanical energy at that time?**Gravitational Potential Energy = mass x 9.8 m/s² x height**What is the gravitational potential energy of the book sitting on the shelf?**Which object has the most kinetic energy?**Three objects are rolling down a hill at the same speed. Object 1 has a mass of 1 kg; object 2 has a mass of 1.5 kg, and object 3 has a mass of 3 kg.**Which of the following best illustrates chemical potential**energy?**True or false**An object with a greater mass has greater kinetic energy.**Think about it…**If Tim were to jump out of a hot air balloon high in the sky, describe how gravitational potential energy changes as he falls. Then, describe how Tim’s kinetic energy changes when the parachute opens.**Think about it…**Describe the relationship between a moving object’s mass and its kinetic energy. Assume a balloon and a basketball are thrown at the same speed, which ball would have the most kinetic energy and why?**PAIR SHARE**Describe the relationship between a moving object’s mass and its kinetic energy. Assume a balloon and a basketball are thrown at the same speed, which ball would have the most kinetic energy and why? If Tim were to jump out of a hot air balloon high in the sky, describe how gravitational potential energy changes as he falls. Then, describe how Tim’s kinetic energy changes when the parachute opens.
