This term means a push or a pull.

What is force?

100

Give the reaction to hand hits ball

What is ball hits hand?

100

This property of matter keeps an object at rest or in motion unless acted upon by an external force.

What is inertia?

100
This states that an object in motion remains in motion unless an unbalanced force acts upon it.
What is Newton's First Law of Motion?
100

This variable is intentionally changed by the scientist to observe its effect.

What is the independent variable?

200
This law states that the mass of an object is inversely proportional to the acceleration that is undergoes.
What is Newton's Second Law of Motion?
200

Give the reaction to dog pulls boy

What is boy pulls dog?

200
Because of inertia, a resting object will remain at ________.
Rest
200
This states that an object at rest remains at rest unless an outside force acts upon it.
What is Newton's First Law of Motion?
200

This variable is measured or observed as a response to changes in the experiment.

What is the dependent variable?

300
True or False: If an object is pushed with more force, it will move faster, or have a greater acceleration.
What is true?
300
This type of diagram represents all of the forces acting on a single object.
What is a free-body diagram or force diagram?
300

Because of inertia, a moving object will keep ________.

Moving

300
This law states that forces come in pairs.
What is Newton's Third Law of Motion?
300

These variables are kept the same throughout the experiment to ensure the test is fair.

What are control variables?

400
This is one form of the equation that represents Newton's Second Law of Motion.
What is F=ma, a=F/m, or m=F/a.
400
This is one particular everyday situation in which we see Newton's Third Law of Motion occuring.
What is (answers vary-must demonstrate forces acting in pairs and equal and opposite to one another).
400
True or false: All objects have inertia, whether they are moving or not.
True
400
This law describes the need for an unbalanced force in order for an object to undergo an acceleration (aka, a change in speed).
What is Newton's Second Law of Motion?
400

In an experiment testing how sunlight affects plant growth, this variable is the amount of water given to the plants.

What is a control variable?

500

This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to this property.

What is mass?)

500
What are the four types of forces that can be represented by arrows on a free-body diagram?
What are the F(w), F(n), F(a), and F(f)?
500
Inertia can best be described as _____.
The tendency of any object to resist change and keep doing whatever its doing
500
This law states that for every force that object A applies on B, object B pushes the same amount of force back, but in the opposite direct, of object A.
What is Newton's Third Law of Motion?
500

In an experiment testing the effect of temperature on ice melting, this variable would be the time it takes for the ice to melt.

What is the dependent variable?
