- 1What are the 2 main categories of energy that all types of energy fall into?Kinetic & Potential Energy
- 2What are the 7 types of energy?Mechanical, Thermal, Radiant, Nuclear, Electrical, Sound, & Chemical
- 3What factors determine something’s kinetic energy?Mass and velocity
- 4What factors determine something’s gravitational potential energy?Mass and height
- 5What is work as it relates to energy?Energy is transferred to an object
- 6What is the relationship between height and speed? In other words, as height increases, what happens to the speed of an object?As the height of an object increases, the speed decreases
- 7State the law of conservation of energyEnergy cannot be created or destroyed, only transformed into different forms
- 8Something can have potential energy due to two things. What are they?Position & Chemical
- 9Does energy change form?Yes
- 10How much kinetic energy does a 20kg ball have that is moving 30m/s?9000 J
