An object will continue to remain at rest or in uniform motion unless acted upon by an external, unbalanced force.
What is Newton's First Law of Motion?
This is the basic unit of length in the metric system (about 39 inches).
What is a meter?
10 millimeters equals this amount.
What is 1 cm (centimeter)?
The curved surface of a liquid.
What is meniscus?
This is a disturbance that carries energy through matter or space.
What is a wave?
In the absence of an unbalanced fore, we get this.
What is constant velocity?
Like the money system in the U.S., the metric system is based on a system of this.
What is a system of tens?
1,000 meters equals this amount.
What is 1 km (kilometer)?
Method of measuring volume of irregularly shaped-objects.
What is displacement of water method?
Light can travel from the sun to Earth across empty space because light waves do not need a medium. This is another name for light waves.
What is an electromagnetic wave?
These are the IAs for Physical Science.
Who are Spooner, Mary, Kristen, and Marianna?
A common tool for measuring length in the metric system.
What is a meterstick?
This amount is equal to 1,000 cubic centimeters.
What is a liter?
This is the basic unit of mass in the metric system.
What is a gram?
The matter through which a wave travels.
What is a medium?
Force=Mass x Acceleration
This law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
What is Newton's Second Law of Motion?
1/100 of a meter. One meter has 100 of these.
What is a centimeter?
1 milliliter is this amount.
What is 1/1000 of a liter?
An instrument used to measure mass.
What is a balance?
This means to move rapidly back and forth.
What is vibrate?
For every action force, there is an equal and opposite reaction force.
What is Newton's Third Law of Motion?
1/1000 of a meter. one meter has 1,000 of these in it.
What is a millimeter?
These waves require a medium.
What are mechanical waves?
These are the reasons ships don't sink in water.
What are buoyancy (air in the hull) and water displacement?
All of the sounds you hear are made when matter does this.
What is vibrates?
