100
The energy that an object has because of the position, shape, or condition of the object. Example: Gravitational, elastic, chemical
What is Potential Energy? What are the different kinds of energy?
100
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The rate of change of momentum is proportional to the imposed force and goes in the direction of the force. For every action there is an equal and opposite reaction.
What are the Newtons 3 laws of motion?
100
A motor transforms electrical energy into mechanical energy, and a generator transforms mechanical energy into electrical energy.
What is the difference between generators and motors?
100
Solids - Definite shape, definite volume, low particle movement. Liquids - no definite shape, definite volume, medium particle movement. Gases - no definite shape, no definite volume, high particle movement.
What are the shape volume, and particle motion of solids, liquids and gases?
100
Weight is a measurement of how hard gravity is pulling on an object. Mass is a measurement of how much matter is an object. W=m/g
What is the difference between mass and weight? How do you calculate weight?
200
Energy that a body possesses by virtue of being in motion. Heat energy, light energy, etc.
What is kinetic energy? What are the different types of kinetic energy?
200
A car rolling down a hill. A light car crashing into a wall creates less force than a heavy car crashing at the same speed into the same wall. When you walk, you push onto the ground and it pushes back onto to.
What is an example of each of Newton's 3 laws of motion?
200
A magnet run on electricity. You can increase the strength by increasing the number of coil turns, increasing the current, or increasing the voltage.
What is an electromagnet and how do you increase its strength?
200
It increases
What happens to the particle motion if there is an increase in temperature?
200
The standard unit for mass and weight in the metric system.
What are Kilograms and Newtons?
300
Energy can neither be created nor destroyed. A fan (electrical to kinetic), a lightbulb (electric to heat and light)
What is the Law of Conservation of Energy? What are some examples of energy transformation?
300
The tendency to remain unchanged.
What is inertia?
300
A magnet that retains its magnetic properties in the absence of an inducing field or current.
What is a permanent magnet?
300
The minor component in a solution, dissolved in the solvent. The liquid in which a solute is dissolved to form a solution.
What is the definition of a solute? What is the definition of a solvent?
300
Sour taste, turn blue litmus paper red, react strongly with metals. Orange juice, soda, milk.
What are the characteristics of acids? What are some examples?
400
The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. The transfer of heat from one place to another by the movement of fluids. Energy that is radiated or transmitted in the form of rays or waves or particles
What is conduction? What is convection? What is Radiation?
400
Forces are balanced when the forces pushing (or pulling) an object in one direction are the same size as the forces acting in the opposite direction. Any force which contributes to a non-zero net force on an object, also the force that makes an object change its motion
What are balanced forces? What are unbalanced forces?
400
A circuit having its parts connected serially. A closed circuit in which the current divides into two or more paths before recombining to complete the circuit. A circuit where the electricity flows one way. A circuit where electricity changes directions. Old Christmas lights. New Christmas lights. A battery. A microwave
What is a series, parallel, direct, and alternating current? What is an example of each?
400
Heat it, stir it, increase the surface area.
What are at least three different ways you can increase the rate of dissolving?
400
Bitter taste, turn red litmus paper blue, don't react with metals. Blood, ammonia, baking soda.
What are the characteristics of bases? What are some examples?
500
Laying on a hot rock to warm yourself. Water boiling. Heat from a fire.
What is an example of conduction? What is an example of convection? What is an example of radiation?
500
The rate at which the earth's gravity pulls on all objects.
What is 9.8 meters per second per second.
500
Static charges can occur when you shuffle your feet on carpet, rub a balloon on a sweater, comb your hair a lot on a dry day. Touch metal, touch another person, increase the humidity.
What are three ways static charges and/or discharges can occur? What are examples of each?
500
Saturated- the most a solute will dissolve at a certain temperature. Unsaturated - an amount under the amount a solute will dissolve at a certain temperature. Supersaturated - an amount more than the amount a solute will dissolve at a certain temperature.
What is the difference between a saturated solution, unsaturated solution, and supersaturated solution?
