increasing its speed
what is the way of increasing the kinetic energy of an object?
conduction, convection, radiation
what are the 3 types of thermal energy
This machine use gravitational energy to pull up heavy weight.
What is a gravity battery
True or false, the higher an object is above the ground the more gravitational potential energy it has.
true
What type of energy transformation occurs in the following scenario: turning on a flashlight
Kinetic energy depends on mass and this.
What is temp?
The movement of heat from one object to another
What is conduction?
this machine uses a wheel and axle (hint: you use it everyday)
what is a doorknob?
Elastic potential energy
type of energy is stored in a stretched rubber band
What type of energy transformation occurs in the following scenario: A windmill spinning
What is mechanical to electrical?
car driving, falling ball, spinning wheel
What is a everyday examples of everyday situations where kinetic energy is present?
Steam rising
What is convection?
This machine uses mechanical energy to move.
What are car engines?
a ball rolling
potential energy is converted into kinetic energy
What type of energy transformation occurs in the following scenario: eating an apple and the going to work out.
What is chemical to mechanical and thermal?
They can be converted into each other
what is the relationship between kinetic and potential energy?
Everything has this type of energy
What is thermal energy?
Uses thermal energy to make its engine move
what is a heat engine?
When a battery powers a lightbulb
where chemical potential energy is converted into other forms of energy
joules
What is the unit of kinetic energy?
Can not be created nor destroyed, only transferred.
what is energy?
uses kinetic energy to rotate blades which makes it move
What is a windmill?
The position of an object with the system changes relative to object
how does the potential energy of a system can choose without any work being done?
