Physics Final: Ch. 2 Newton's Laws of Motion

Inertia is defined as a

property of matter

An object tends to remain in motion

without the need of a force

If the mass of an object does not change, a constant net force on the object produces constant

acceleration

Newton's second law focuses on

acceleration

If an object's mass decreases while a constant force acts on it, the acceleration

increases

When an apple that weighs 1-N is held at rest above your head, the net force on the apple is

0 N

Action and reaction forces are parts of

a single interaction

A quick jerk on a sheet of paper beneath a box of cereal doesn't topple the box, which best illustrates that

the box has inertia

The emphasis of the orange-and-apple sequence in your text is

to define systems

You cannot exert a force on a wall

unless the wall simultaneously exerts the same amount of force on you
