100
A testable explanation?
What is a hypothesis?
100
This is when an object changes position with respect to a point of reference.
What is motion?
100
The type of force that is occurring when a bike is leaning against a tree?
What is a balanced force?
100
It measures the speed at a given point in time.
What is instantaneous speed?
100
By dividing distance by time.
How is speed calculated?
200
It is the variable usually plotted on the x-axis.
What is the independent variable?
200
The rate at which velocity changes over time.
What is acceleration?
200
A push or pull
What are two examples of forces?
200
The force that opposes motion between two surfaces.
What is friction?
200
The units acceleration is measured in.
What is m/s²?
300
This is what you measure in the experiment and what is affected during the experiment.
What is the dependent variable?
300
This is when an object is traveling equal distances in equal amounts of time.
What is constant speed?
300
The larger the mass of the object, the greater the gravity.
How is gravity affected by mass?
300
It is the part of the experiment that stays the same.
What is the constant?
300
By using lubricants such as motor oil, wax and grease.
How can unwanted friction be lowered?
400
It is the type of graph that is best used to show changes in data over time.
What is a line graph?
400
This is the type of acceleration when an object's velocity is decreasing; the object is slowing down.
What is negative acceleration?
400
What is unwanted friction?
400
It is acceleration that occurs in circular motion.
What is centripetal acceleration.
400
It is where the constant velocity of falling object whe the force of air resistance is equal in magnitude and opposite in direction to the force of gravity.
What is terminal velocity?
500
The steps for the scientific method.
What is observation, research, hypothesis, experiment, analysis and conclusion.
500
This is the change of an object's position relative to its starting position and always includes direction.
What is displacement?
500
This is what Newton's Second law of Motion is called and how it is defined.
What is the Law of Acceleration and the force of an object is equal to its mass multiplied by its acceleration?
500
It is the Newton's Law represented here:
What is Newton's Third of Law of Motion?
500
They are the two components of projectile motion.
What are horizontal and vertical?
600
This is the combination of all forces acting on an object.
What is net force.
