Vocabulary
The ability to cause change
What is energy?
energy that is possessed by an object due to its motion or due to its position
What is kinetic energy?
when energy changes forms from one type to another.
What is energy transformation?
a pendulum eventually comes to a stop when all of it's energy is converted to heat.
What is energy transformation in a pendulum?
Energy of motion
What is kinetic energy?
stored energy due to interactions between particles or objects
What is potential energy?
energy that is possessed by an object due to its motion or due to its position
what is mechanical energy?
When energy moves from one location to another
What is energy transfer?
What is the highest point?
The energy in the core of an atom.
What is nuclear energy?
the resistance force that one surface or object encounters when moving over another
What is friction?
a type of kinetic energy due to the motion of particles that make up an object
What is thermal energy?
Plugging in a phone
What is an example of energy transformation?
If a pendulum has more of this, it will cause it to slow down
What is friction?
Chemical energy is a form of this
What is potential energy?
the transfer of energy to an object by using a force that causes the object to move in the direction of the force
What is work?
a type of kinetic energy carried by an electric current, like through the motor of a fan
What is electrical energy?
A bat hitting a ball
What is an example of an energy transformation?
This is the force that pulls the pendulum down when it is dropped
What is gravity?
The factors of potential energy
What are mass and height?
The distance an object travels per unit of time; one of the factors that determines an object's kinetic energy
What is speed?
energy that cannnot be used for movement (usually thermal energy)
What is waste energy?
the mitochondria of your muscle cells break down glucose and use the energy to contract the muscle
What is an example of energy transformation
When increasing the friction in a pendulum, its kinetic energy decreases because the amount of this form of energy rises
What is thermal energy?
The factors of kinetic energy
What are mass and speed?
