• The pencil lead breaks

• The pencil writes on the paper

• The paper pushes back up on the pencil

• The table pushes up on the paper

Which of the following laws best describe the reason objects "fly forward" during a head on car collision.

• Newton's 1st Law (inertia)

• Newton's 2nd Law (F=ma)

• Newton's 3rd Law (Action/Reaction)

What is the definition of inertia

• The force that keeps an object moving

• The resistance to a change in motion related to mass

• The amount of forward motion an object has

What determines the amount of an inertia an object has?

• The gravitational pull

• The motion of the object

• The mass of the object

• The velocity of the object

What is true regarding forces acting on an object that is accelerating?

• The forces are balanced

• The forces are unbalanced

• The net force is zero

• More information is needed
