A crumpled piece of paper hits the ground before a flat sheet of paper because

the acceleration of gravity is greater on the crumpled paper.

there is more air resistance against the flat paper.

the crumpled paper is more massive

the crumpled paper is less massive.

A greater applied force is required to move an object with a greater mass than one with a smaller mass.

True

False

Which one needs a greater net force to move, a kilogram of feathers or a kilogram of iron?

feathers

iron

same

depends on their friction

After a cannonball is fired into frictionless space, the amount of force needed to keep it going equals

twice the force with which it was fired

the same amount of force with which it was fired

1/2 the force with which it was fired

zero, since no force is required to keep it moving.

19.

You can move heavy boxes by sliding them over the ground, or you can put them on a dolly and then roll them over the ground. Which way makes it easier to move the boxes? Why?

Sliding the boxes on the floor is easier than using the dolly because rolling friction is less than sliding friction

Sliding the boxes on the floor is easier than using the dolly because sliding friction is less than rolling friction.

Rolling the boxes over the floor on the dolly is easier because sliding friction is less than rolling friction.

Rolling the boxes over the floor on the dolly is easier because rolling friction is less than sliding friction.
