Motion
Velocity & Acceleration
Newton's Laws
100
This changes the motion of an object.
What is force?
100
This type of force depends on the types of surfaces in contact and the force pressing them together.
What is friction?
100
Motion is relative to this object.
What is a reference point?
100
This describes an object's speed combined with the direction in which it is moving.
What is velocity?
100
This scientist stated rules that describe the effects of motion on objects.
Who was Sir Issac Newton?
200
This is the force that occurs when two unequal forces act in opposite directions.
What is net force?
200
This force prevents two objects from sliding past one another.
What is static friction?
200
This term describes how far an object has moved.
What is distance?
200
This describes the rate of change of velocity.
What is acceleration?
200
This law states that for every action there is an equal but opposite reaction.
What is Newton's Third Law?
300
This describes the tendency of an object to resist a change in it's motion.
What is inertia?
300
This is the force that opposes the motion of two objects sliding past one another.
What is sliding friction?
300
This term describes how far away an object is from it's original starting point.
What is displacement?
300
A person pushing a snowball up a hill is exhibiting what kind of acceleration?
What is negative acceleration.
300
This is the unit of measurement for force.
What is a Newton?
400
This occurs when your net forces are equal and no change in velocity takes place.
What is a balanced force?
400
This is the force that exists between an object and what it is rolling on.
What is rolling friction?
400
The formula s=d/t is used to find what?
What is speed?
400
Water falling over a waterfall has what kind of acceleration?
What is positive acceleration?
400
This Newton's Law is also referred to as the law of inertia.
What is Newton's First Law?
500
This force depends on the mass of two objects and the distance between them.
What is gravity?
500
This is the highest speed a falling object will reach.
What is terminal velocity?
500
This term describes the speed of an object at any given point in time.
What is instantaneous speed?
500
a=(vf - vi)/t vf represents this.
What is final velocity?
500
a=Fnet/m Which of Newton's Laws does this equation represent?
What is Newton's Second Law?
