Energy
This is the ability to cause change.
What is energy?
This is energy due to motion.
What is kinetic energy?
This states that energy cannot be created or destroyed.
What is the law of conservation of energy?
This is the sum of the kinetic energy and the potential energy of all the particles that make up that object.
What is thermal energy?
This is the transfer of thermal energy by collisions between particles that make up matter.
What is conduction?
This is the transfer of energy?
What is work?
This is energy that is stored due to the interactions between objects.
What is potential energy?
This is the sum of the kinetic and potential energy of the objects in a system.
What is mechanical energy?
This is the measure of the average kinetic energy of the particles that make up the object.
What is temperature?
This is the transfer of thermal energy in a fluid by the movements of warmer and cooler fluid.
What is convection?
This is anything around which you can imagine a boundary.
What is a system?
This is a type of potential energy where energy is stored by compressing or stretching an object.
What is elastic potential energy?
In a projectile motion, as there is a high KE there is a low _______.
What is GPE or gravitational potential energy?
This is energy that is transferred between objects due to a temperature difference between the objects.
What is heat?
This is the transfer of energy by electromagnetic waves, such as light and microwaves.
What is radiation?
A tennis ball and racket or a shelf and a vase are considered to be examples of this.
What is a system?
This type of potential energy is energy that is due to the gravitational forces between objects.
What is gravitational potential energy?
In order to keep a swing going on Earth, you must constantly put energy into the system. The reason is because of this....
What is friction or air resistance?
This is how mass and thermal energy are related.
When the mass of an object increases, the thermal energy increases?
This is a material in which thermal energy moves slowly.
What is a thermal insulator?
Both energy and work are measured in this.
What are joules?
Gravitational potential energy is calculated by this equation.
What is: GPE = mgh?
The rate at which energy is converted is power. It can be found by this equation:
What is: P = E/t?
When the material is the amount of heat needed to raise the temperature of 1 kg of that material by 1 degree Celsius it is finding this.
What is specific heat?
Give an example of each type of energy transfer.
