A graph showing distance divided by time gives information about this scalar quantity.
What is speed?
100
This term describes a quantity that is only a value/magnitude and direction doesn't matter.
What is scalar?
100
This word describes newton's first law. It is defined as the tendency of an object to resist change. If an object is moving, it will stay moving. If an object is not moving, it will stay still.
What is inertia?
100
This is the friction of an unmoving object.
What is static friction?
100
This law says that a book will stay sitting on a desk unless force is applied to move it.
What is newton's first law?
200
A graph showing displacement divided by time gives information about this vector quantity.
What is velocity?
200
This is an example of a scalar quantity.
What is speed or distance or mass or time? (and there ARE other examples too!)
200
The more force applied to an object, the more ______ it will experience.
What is acceleration?
200
This is the majority of the friction you experience when using a skateboard or roller skates.
What is rolling friction?
200
This law describes pairs of forces.
What is newton's third law? (These are action/reaction pairs.)
300
A flat line (with no slope) tells you what on a distance vs. time graph?
What is the object is not moving?
300
This is an example of a vector quantity that occurs when an object changes speeds.
What is acceleration?
300
A force is applied to a heavy object. If the same amount of force is applied to an object with less mass, it will have ______________ acceleration.
What is greater (more)?
300
This is the friction against an eraser when it is dragged across a piece of paper.
What is sliding friction?
300
This law is also called the law of inertia.
What is newton's first law?
400
A flat line (with no slope) tells you what on a velocity vs. time graph?
What is the object is moving with a steady, constant speed?
400
A slow moving heavy object can likely have the same momentum as a _____ moving light object.
What is fast?
400
In the equation f=ma, what variable is likely not going to change for an object?
What is its mass?
400
This is the friction you experience when swimming in a pool.
What is fluid friction?
400
This law says there is a relationship between force, mass, and acceleration.
What is newton's second law?
500
On a distance vs. time graph, if a line is curved and looks like a "J", its motion is...
What is speeding up?
500
If you drop a ball from the top of the school, this is how fast it was traveling when it hit if it fell for 4 seconds.
What is 40 m/s? (Actually 9.8*4=39.2m/s.)
500
This is a special name for the force needed to overcome inertia or to accelerate an object.
What is an unbalanced force?
500
This is a special type of fluid friction experienced by sky divers.
What is air resistance?
500
Using newton's 2nd law, this is the mass of an object that is accelerating at 2 m/s/s when a force of 10 N is applied.
