When an object changes position over time when compared with a reference point.
What is motion?
100
A push or pull.
What is a force?
100
A force of attraction between objects that is due to their masses.
What is gravity?
100
An international system of measurement.
What is metric system?
100
The acceleration of an object depends on the mass of the object and the amount of force applied.
What is Newton's 2nd Law of Motion?
200
The object that appears to stay in place.
What is a reference point?
200
The force that results from combining all the forces exerted on an object.
What is net force?
200
The amount of matter in an object.
What is mass?
200
Identify a problem
Form a hypothesis
Create an experiment
Perform an experiment
Analyze data
Communicate results
What is the Scientific Method?
200
An object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
What is Newton's First Law of Motion?
300
Speed = Distance/Time
What is the equation to determine average speed?
300
When the net force on the object is greater than zero.
What is an unbalanced force?
300
A measure of gravitational force.
What is weight?
300
Grams
What unit do you use when measuring mass?
300
The tendency of all objects to resist any change in motion.
What is inertia?
400
The speed of an object in a particular direction.
What is velocity?
400
Then the forces applied to an object produce a net force of zero.
What is a balanced force?
400
The unit of newtons.
What is how forces are expressed?
400
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
What is Newton's Third Law of Motion?
500
The rate at which velocity changes.
What is acceleration?
500
Sliding, rolling, fluid and static.
What are four types of friction?
500
When the net force is zero and a falling object stops accelerating.
What is terminal velocity?
500
The circumference of a bubble.
What is what we measured during the Chewing Gum Lab?
500
(a = F/m) or (F = m x a)
What is the expression of Newton's second law mathematically?
