Science test 10/1/16 Types of energy Flashcards
What is kinetic energy?
Kinetic energy is the energy of moving things
What are some examples of kinetic energy?
particles moving in matter (such as particles in air or water)
What are some examples of kinetic energy being transformed into potential energy?
when an elastic object such as a spring stretches out to its longest position,
What is the relationship between net force applied, mass, and change in motion of an object?
When a net force is applied to an object that has mass, the object will accelerate in the direction of the net force.
What is potential energy and what are some examples of it?
Potential energy is energy that is stored in an object and can be released at a later time. Examples of potential energy in a book resting on a table above the ground,
What are two types of potential energy?
gravitational potential energy, chemical potential energy
What is the difference between potential energy and kinetic energy?
Potential energy is stored energy while kinetic energy is the energy of motion.
How does potential energy turn into kinetic energy?
.If a book is moved to the edge of the table, it will fall to the ground. As it falls the potential energy changes into kinetic energy, which is the energy of motion.
what is the difference between heat and temputure?
Heat is energy in transit, whereas temperature is a quantitative measure of the average translational kinetic energy of the molecules of a substance.
How can energy be released or stored by chemical means?
Chemical energy is energy that is stored in the bonds of chemical compounds. When these bonds are broken during a chemical reaction, energy is absorbed from the surroundings; energy is stored in the chemical bonds. When new bonds are formed, energy is released to the surroundings, often as heat.
How is thermal energy transferred?
Heat can be transferred from one object to another by radiation, conduction, or convection.
What is the process for developing potential design solutions?
This process often begins with the open-ended goal of brainstorming ideas. From there, it moves to the generation of possible solutions that, by necessity, involve constraints and criteria. Modeling plays a crucial role in this process; the models can take numerous forms.
What is heat?
Heat is energy that is transferred from a warmer object to a cooler object.
what is temputure?
Temperature is a measure of the average kinetic energy of the particles that make up an object.
What is the particle model of matter?
The particle model of matter states that all matter is made of tiny particles that are in constant motion, have empty spaces between them and interact with each other.
