Describing Motion & Force
When its position is changing, an object is This.
What is "the object is in motion"?
This is calculated by putting distance over time.
What is speed?
"An object at rest stays at rest; an object in motion stays in motion" is this.
What is "Newton's First Law of Motion"?
Who is Sir Issac Newton?
What are examples of "good reference points"?
No, a car would not be considered "in motion" relative to this.
What is the driver?
This is the most common unit of speed.
What is meters per second?
"For every action, there is an equal and opposite reaction", is this.
What is "Newton's Third Law of Motion"?
Correct Answers:
Rolling, Sliding, Fluid, and Static
Meters per second, squared.
What is the unit of measure for acceleration?
Answer 2: These are forces that DON'T require objects to touch each other.
What are "contact and noncontact forces"?
Speed, but with direction.
Force = Mass x Acceleration is this.
What is "Newton's Second Law of Motion"?
This is stored energy of an object based on an object's position.
What is (gravitational) potential energy?
This is resistance to change in motion.
What is inertia?
This force counteracts gravity and pushes objects upward.
What is the normal force?
This is calculated by subtracting the initial speed from the final speed of an object and putting that over time.
What is acceleration?
This is the unit that says I can move a 1 kilogram object a 1 meters per second.
What is a Newton?
One of these is the amount of matter, the other is the force of gravity.
What is the difference between weight and mass?
If a net force acts upon an object, it will do this.
How can something accelerate?
This happens when a nonzero net force acts on an object.
What is motion?
On a graph, they show distance and time respectively.
What are the x and y axis'?
What is "The Law of Inertia"?
The types of surfaces and the force on the objects.
What are the two factors that affect friction?
An offensive lineman has more inertia than a quarterback because of this.
