inertia
this property of matter causes an object to resist any change in its motion
what is inertia
This 17th-century scientist's Second Law of Motion states that force equals mass times acceleration.
who is Issac Newton
newton third law states that for every action there is one of these that is equal and opposite
what is reaction
Unlike kinetic energy, which is energy of motion, potential energy is often defined as this type of energy.
What is stored energy?
This "educated guess" is a testable prediction that often uses an "lf.. then..." format.
What is a hypothesis?
newtons first law is often referred to by the name of its property
what is law of inertia
According to the second law, if you keep mass constant and double the force, this happens to the acceleration.
What is it doubles?
to propel itself forward a rocket pushes exhaust gases in this direction
what is backwards
Gravitational potential energy depends on two main factors: the object's mass and this, its distance above the ground.
What is height
In an experiment, this is the factor that you intentionally change to see how it affects the outcome. variable?
What is the independent
This physical quantity is the primary measure of an object's inertia; the more of it an object has, the harder it is to move,
What is mass?
This is the standard metric unit used to measure force, defined as 1 kg-m/s.
What is a Newton?
these pairs of forces always occur simultaneously and never act on the same object
what are action reaction pairs
This type of potential energy is found in stretched rubber bands or compressed springs.
What is elastic potential energy?
This 11-letter word describes a state of balance or stability in a biological system.
homeostasis?
To demonstrate inertia, you might quickly pull a tablecloth out from under these items without moving them.
What are dishes
Acceleration is defined as the rate of change of this over time.
What is velocity?
if you hit a wall with 50 newtons of force this is the amount of force the wall exerts back on your hand
what is 50 newtons
This is the specific type of potential energy stored in the bonds of food molecules and gasoline.
What is chemical potential energy?
This term refers to the
"thickness" or internal friction of a fluid, like honey having more of it than water.
What is viscosity?
Because it has both magnitude and direction, force is classified as this type of mathematical quantity.
what is vector
this backwards kick of a firearm after is is discharged is a classic example of newtons third law
what is recoil
In the formula PE = mgh,
the letter "g" represents this constant value, approximately 9.8 m/s.
What is acceleration due to gravity?
Scientists use this 12-letter term for the process where a gas turns directly into a solid without becoming a liquid.
What is or desublimation deposition
