Q4 Unit 1 Test

Question 1

On a position-time graph, what does the slope of the line represent?

Question 2

A flat, horizontal line on a position-time graph indicates that the object is:

Question 3

An object travels 120 meters in 40 seconds at a constant speed. What is the speed of this object?

Question 4

On a position-time graph, Line X has a steeper slope than Line Y. What does this tell you?

Question 5

A curved line on a position-time graph indicates that the object is:

Question 6

Two lines cross on a position-time graph at time = 8 seconds. What does this crossing point mean?

Question 7

A line on a position-time graph slopes downward from left to right. This means the object is:

Question 8

What is the correct formula for calculating speed?

Question 9

What is the SI unit used to measure force?

Question 10

When the forces on a moving object are balanced, the object will:

Question 11

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?

Question 12

A net force of 24 N acts on a 6 kg object. What is the object's acceleration?

Question 13

Newton's Second Law states that Force equals:

Question 14

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:

Question 15

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?

Question 16

In Newton's Third Law, the action force and the reaction force act on:

Question 17

A passenger in a car lurches forward when the driver suddenly brakes. This happens because of the passenger's:

Question 18

What does the term 'net force' mean?

Question 19

When two north poles of different magnets are brought close together, they will:

Question 20

If you break a bar magnet in half, what will you have?

Question 21

Which scientist first demonstrated that an electric current produces a magnetic field?

Question 22

Which of the following is an advantage that electromagnets have over permanent magnets?

Question 23

A student wants to make an electromagnet stronger. Which action will MOST LIKELY increase its strength?

Question 24

'You got a D on the last test, so your opinion about the project does not matter.' Which logical fallacy is this?

Question 25

'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?

Question 26

A straight line on a position-time graph means the object is accelerating.

Question 27

Balanced forces result in no change to an object's motion.

Question 28

According to Newton's Second Law, doubling the force on an object will double its acceleration (if mass stays the same).

Question 29

Newton's Third Law action-reaction forces act on the same single object.

Question 30

Like magnetic poles attract each other.

Question 31

An electromagnet can have its poles reversed by reversing the direction of the electric current.

Question 32

The Bandwagon fallacy argues something is true because a famous person said it.

Question 33

A Red Herring fallacy introduces an unrelated topic to distract from the original argument.

Question 34

Match each scenario to the Newton's Law it BEST demonstrates.

A hockey puck slides across frictionless ice at constant speed forever
Pushing a heavy cart requires more force than a light cart for the same acceleration
When a rocket pushes exhaust gases downward, the rocket moves upward
A sleeping cat stays sleeping until the dog pushes it off the couch
Question 35

Match each term to its correct definition.

Inertia
Net force
Velocity
Force
Question 36

Match each statement to the fallacy it demonstrates.

'Everyone on the team is doing it, so you should too.'
'This is the best plan because there is no better plan.'
'You want fewer quizzes? So you want to eliminate all testing?'
'Either you join the club, or you have no school spirit.'
