When an object’s distance from another object is changing
What is Motion
100
A push or a pull exerted against an object.
What is Force
100
The force that attracts a body toward the center of the earth, or toward any other physical body having mass.
What is Gravity?
100
A change in a scientific experiment.
What is Variable?
100
This process is the way to defend an answer. The acronym is CER
What is Claim, Evidence, Reasoning?
200
The speed and direction an object is traveling
What is Velocity
200
An unseen force causes a soccer ball to roll farther on concrete than in the grass.
What is Friction
200
If the mass of Earth doubled, what would happen to your weight?
It would increase.
200
These are the variables which a scientist attempts to keep the same during every trial.
What are controls/constants
200
The answer to the question which is typically only 1 sentence long.
What is Claim?
300
An object which can be used to determine if another object is in motion.
What is a reference point
300
The unseen force that allows a skydiver to fall to the ground safely using a parachute?
What is Air Resistance?
300
If a bowling ball and a penny were dropped inside a vacuum room at exactly the same time, in what order would they hit the ground?
They would hit at the same exact time.
300
The 1 variable which is changed on purpose. This is the variable which is being tested
What is the independent variable?
300
The data or results are included in this part of your defend.
What is Evidence
400
When an object changes speed or direction.
What is Acceleration
400
This force increases as the mass of an object increases.
What is Gravity?
400
As the mass of an object increases, what also increases.
Gravity.
400
The variable which is also the data used in the results.
What is dependent variable?
400
This is where you include scientific principles and explain why.
What is Reasoning.
500
Which of the following is NOT an example of acceleration?
a. A horse galloping 27 m/s south
b. A roller coaster coming to a stop at the end of the ride
c. A plane taking off
d. A person driving at 50 m/h along a curving road
it is A
500

Friction
Gravity
air resistance
500
He is the scientist who determined that weight does not affect how fast an object will fall.
