Amazing Facts about Force and Weight

What is the weight of a calculus book resting on the floor of a classroom?

The weight of the calculus book is 20 N.

Answer:

The weight of the calculus book resting on the floor of a classroom is 20 N.

Weight is a force that is exerted on an object due to gravity. In this case, the calculus book has a weight of 20 N, which means that the force due to gravity acting on the book is 20 N. This weight is what causes the book to stay on the floor of the classroom.

It's important to note that weight is different from mass. Mass is a measure of the amount of matter in an object, while weight is the force exerted on that object due to gravity. The weight of an object can vary depending on the gravitational pull of the environment it is in.

So, the weight of the calculus book resting on the floor of a classroom is 20 N, which is the force of gravity acting on the book in that particular environment.
