Measuring Motion
What is Force?
Friction
100
This element plays a central role in the chemistry of living things.
What is carbon?
100
These are biochemicals composed of sugar molecules.
What are carbohydrates?
100
This shows an objects change in position relative to a reference point.
What is motion?
100
In science, this is a push or a pull.
What is force?
100
This force opposes motion.
What is friction?
200
These are the three types of carbon backbones.
What is straight chain, branched chain, and ring?
200
These biochemicals consist of fats, waxes, and oils.
What are lipids?
200
This is the direction an object would move along a grid if it went to the right.
What is the positive direction?
200
This is the SI unit used to describe magnitude, or size, of force.
What is newton?
200
This is known as the friction between "moving" surfaces.
What is kinetic friction?
300
These are the three types of bonds between carbon atoms.
What is single, double, and triple?
300
These biochemicals make up the hemoglobin in our red blood cells.
What are protiens?
300
To find this you would need to divide the total distance by the total time.
What is average speed?
300
To calculate this number you would need to add or substract the combination of forces acting on an object.
What is net force?
300
This force, when applied, does not cause the object to move.
What is static friction?
400
The amount of bonds one carbon atom can form.
What is four?
400
These biochemicals include adenine, thymine, guanine, and cytosine.
What are nucleic acids?
400
This is a measurement of an objects speed and direction.
What is velocity?
400
This is a type of force in which objects are static, or standing still.
What is a balanced force?
400
This is a way we can reduce friction.
What is apply oil?
500
These are six of the elements that molecules in living things are made up of.
What is carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorous?
500
These nucleic acids carry our genic information for reproduction of cells.
What is RNA and DNA?
500
This is the rate at which velocity changes over time.
What is acceleration?
500
This is the type of force that, when applied, creates movement in objects.
What is an unbalanced force?
500
This is a way we can increase friction.
What is apply pressure?
