Question 1

What term is used to describe the tendency of an object to remain in a steady state (at rest or in uniform motion)?

Accepted Answer

inertia

Question 2

What does Newton's First Law say?

Accepted Answer

the velocity of an object will only change if a resultant force is acting on it

Answer

the speed of an object will decrease if a resultant force is acting on it

Answer

the velocity of an object will increase if a resultant force is acting on it

Answer

the velocity of an object will only change if a turning force is acting on it

Question 3

What is the resultant force on a stationary object?

Accepted Answer

$	ext {0N}$

Answer

$	ext {-10N}$

Answer

$	ext {+/-10N}$

Answer

$	ext {10N}$

Question 4

What is the resultant force on an object moving at a steady speed in a straight line?

Accepted Answer

$	ext {0N}$

Answer

$	ext {10N}$

Answer

$	ext {-10N}$

Answer

$	ext {+/-10N}$

Question 5

What will happen to an object if the resultant force on it is not zero?

Accepted Answer

acceleration

Answer

move against the strongest force

Answer

remain stationary or continue to move at constant speed if moving

Answer

no change

Question 6

What is the resultant force on an object with $	ext {20N }$ to the right and $	ext {10N }$ to the left?

Accepted Answer

$	ext {10N right}$

Answer

$	ext {0N}$

Answer

$	ext {-10N right}$

Answer

$	ext {10N left}$

Question 7

What would happen to the motion of an object with a force of $	ext {20N}$ right and $	ext {20N}$ left?

Accepted Answer

remain stationary or continue to move at constant speed if moving

Answer

no change

Answer

move against the strongest force

Answer

accelerate or change velocity

Question 8

Which of these actions is NOT an example of what can happen to an object that accelerates or changes velocity?

Accepted Answer

remaining stationary

Answer

stopping moving

Answer

changing directions

Answer

starting to move

Question 9

What forces are balanced when an object travels at a steady speed?

Accepted Answer

resistive forces = driving force

Answer

driving force = electrostatic force

Answer

resistive forces = weight

Answer

air resistance = friction
