What has more mass, 1-kg of feathers or 1-kg of bricks?

The combination of all the forces acting on an object is the net force.

How does acceleration of an object change compared to its mass?

Acceleration is defined as:

Inertia states than an object:

A force can be defined as a push or pull

If a book is sliding constantly across a friction-less table, how many forces are acting on it?

Inertia can also be compared to laziness.

"How far" means you should look for what variable:

"How long" means you should look for which variable:
