The inertia of the book is equal to the inertia of gravity
The table pushes back up on the book with an equal and opposite force of 20N

Alex pushed against two grocery carts with the same amount of force. Cart A moved but Cart B remained stationary. Which statement best describes why Cart B didn't move?
The more force applied to an object, the harder it is to accelerate the object.
The more mass an object has, the harder it is to accelerate the object.
The less mass that an object has
The less force applied to an object, the easier it is to accelerate the object.
What is defined as a push or pull on an object?
Inertia
Force
Mass
Friction
Newton's 1st Law
Newton's 2nd Law
Newton's 3rd Law
All of Newton’s Laws
Speed can be defined as _____
The speed of an object in a particular direction
distance / time; The rate at which an object moves.
The force applied = the object's mass times the acceleration; F=ma
The constant velocity after which an object stops accelerating
This graph shows that as an object’s mass increases its
inertia increases
inertia decreases
acceleration increases
acceleration decreases
The law of inertia states that a body in motion will remain in motion and a body at rest will remain at rest unless acted upon by a(n) ________________ force.
balanced
unbalanced
equal
strong
