List all the forms of potential energy?
Gravitational,Elastic, and chemical
A jogger with a mass of 40.0 kg is moving forward at a speed of 4 m/s.Calculate the jogger’s kinetic energy from this forward motion
320J
Sally is using mechanical energy to chew her apple.Predict what type of energy will be converted next?
Chemical energy
Identify the dependent variables of GPE
mass and height above the ground
Contrast between kinetic energy and potential energy
Kinetic energy is possessed by an object in motion and potential energy is an object that can store energy without motion due to its position.
Arrange what the energy process: Sun, man, chicken, corn
Sun, corn, chicken, and man
Define the law of conservation of energy
The law of conservation of energy states that energy cannot be created or destroyed.Energy can only be converted from one form to another or transferred from one place to another
If the rock has a mass of 1 kg, which is the speed of the rock after it has fallen for 2 s
20 m/s
Decide which one of these balls has more potential energy and why?
The tennis ball because it has greater mass than the beach ball.
Distinguish between thermal energy and light energy?
Thermal energy is involved in temperature changes or heat transfers. Light energy is an electromagnetic radiation in the forms of visible light and invisible light.
Explain why scientists consider conservation of energy to be a la and not a theory
-Energy cannot be destroyed or created.
Name at least 5 types of energy?
Thermal, chemical, light, electric, potential,sound, kinetic, mechanical, Nuclear, Chemical potential, Elastic potential, and Gravitational. Answers will vary
Describe at least two examples of how different forms of energy can be stored
Elastic potential energy, GPE, and Chemical potential energy
Evaluate: Looking at the picture, where is the most stored potential energy located at?
At the top of the roller coaster because the earth can pull you down through the force of gravity, doing work in the process.
Identify the energy transformation of a flashlight
chemical to light.
