Kinetic Energy
Give 3 examples of an object with Kinetic Energy
objects should have energy of movement
Give 3 examples of an object with Potential Energy
Energy stored in an object (Elastic or Gravitational)
What is the definition of the Law of Conservation of Energy
Energy is not created or destroyed, only transferred.
A baseball mid pitch
kinetic energy
What is the charge of an electron? What is the charge of a proton?
electron = negative , proton = positive
What two things affect Kinetic Energy?
Mass and Speed
What two things affect Potential Energy?
Height and Mass
Describe the energy transfer of a rock thrown straight up from the surface of the earth
Kinetic energy (transfer) increases and Potential energy decreases (start)
A battery before its used
Potential and Chemical Energy
What does the atomic number of an element tell us?
The number of protons and electrons
Which would have more kinetic energy?
A car going downhill or a person going downhill
a car
How much Potential Energy do you have if you are jumping on a trampoline and you are in the air?
Max potential energy
Describe the energy transfer of Food being digested and used to regulate body temperature
chemical energy to heat/thermal energy
What type of Energy does water rushing out of a dam have?
Kinetic Energy
How do the molecules in a solid, liquid and gas move?
solid = very slow and close together
liquid = more fluid movement and space between but close together
gas = very rapid movement and spread apart
What is the Equation for Speed?
Speed = Distance/Time
Which has more Potential Energy?
bowl of pasta with marinara sauce or a salad with no meat or dressing
pasta
Describe the energy transfer of a solar powered calculator when its used
Solar (Light energy) to Potential Energy to Electric Energy
What is the definition of Friction
a force that opposes motion between two surfaces
Name 5 types of Energy
kinetic, potential, solar, electric, mechanical, chemical, nuclear, heat/thermal
Describe HOW mass and speed are related to KE
more mass = more kinetic energy
more speed = more kinetic energy
Give 3 examples of Elastic Potential energy
spring, rubber band, shocks, frog anything that stretches or compresses
Describe the energy transfer of batteries being used in a flashlight
chemical and potential energy to electric energy to light energy
