Q4 Unit 1 Test
On a position-time graph, what does the slope of the line represent?
A flat, horizontal line on a position-time graph indicates that the object is:
An object travels 120 meters in 40 seconds at a constant speed. What is the speed of this object?
On a position-time graph, Line X has a steeper slope than Line Y. What does this tell you?
A curved line on a position-time graph indicates that the object is:
Two lines cross on a position-time graph at time = 8 seconds. What does this crossing point mean?
A line on a position-time graph slopes downward from left to right. This means the object is:
What is the correct formula for calculating speed?
What is the SI unit used to measure force?
When the forces on a moving object are balanced, the object will:
A book is sitting still on a desk. No one touches it. Which of Newton's Laws BEST explains why the book remains at rest?
A net force of 24 N acts on a 6 kg object. What is the object's acceleration?
Newton's Second Law states that Force equals:
When you push on a wall, the wall pushes back on you with an equal force in the opposite direction. This is BEST explained by:
Two balls are pushed with the same 10 N force. Ball A has a mass of 2 kg and Ball B has a mass of 8 kg. Which statement is correct?
In Newton's Third Law, the action force and the reaction force act on:
A passenger in a car lurches forward when the driver suddenly brakes. This happens because of the passenger's:
What does the term 'net force' mean?
When two north poles of different magnets are brought close together, they will:
If you break a bar magnet in half, what will you have?
Which scientist first demonstrated that an electric current produces a magnetic field?
Which of the following is an advantage that electromagnets have over permanent magnets?
A student wants to make an electromagnet stronger. Which action will MOST LIKELY increase its strength?
'You got a D on the last test, so your opinion about the project does not matter.' Which logical fallacy is this?
'If we allow students to retake one test, soon they will want to retake every assignment, and eventually no one will study at all.' This is an example of which fallacy?
A straight line on a position-time graph means the object is accelerating.
Balanced forces result in no change to an object's motion.
According to Newton's Second Law, doubling the force on an object will double its acceleration (if mass stays the same).
Newton's Third Law action-reaction forces act on the same single object.
Like magnetic poles attract each other.
An electromagnet can have its poles reversed by reversing the direction of the electric current.
The Bandwagon fallacy argues something is true because a famous person said it.
A Red Herring fallacy introduces an unrelated topic to distract from the original argument.
Match each scenario to the Newton's Law it BEST demonstrates.
Match each term to its correct definition.
Match each statement to the fallacy it demonstrates.
