## What do you call the force present between the ball and table?

Answer: static friction. Explanation: Static friction is the force present that is keeping the balls on the table from moving or beginning to slide in the first place.

## What normal force does a horizontal table exert on a 3.5 kg book that sits at rest?

The normal force in this case is acting in an opposite manner but equal magnitude to the force of gravity. Hence, the normal force acting on the object is 34.3N.

## When you place the ball on top of the table what force was exerted by the ball and the table?

Answer. Explanation: If a ball is kept on a table then there is gravity acting on it as well as a normal reaction force by the table on the ball. This is correct.

## How would it change if the box were sliding up the plane after an initial shove?

How would it change if the box were sliding up the plane after an initial shove? The force of friction would be a static frictional force, and the normal force would act in the opposite direction to that shown in the diagram. There would be no frictional force.

## When applying a force to a book on a desk the force must be greater than the force of?

Question | Answer |

When applying a force to a book on a desk, the force must be greater than the force of ___ in order for the book to move. | Friction |

True | True or False? A rocket launched into space and a balloon accelerating upward are both examples of Newtons Third Law. |

## Why is a book on a table not a third law pair?

And: If you have a book on a table the book is exerted a force on the table (weight due to gravity), and the table reacts with an equal and opposite force. So one is a gravitational, and the other is not. Therefore this is not Newton’s Third Law as the forces must be of the same type.

## What is the reaction force of a book is pushed down on a table?

Being a reaction to the deforming force that the book exerts on the table, it is, indeed, equal and opposite to it. As long as the normal force exerted by the table on the book does not balance the book’s weight, the book will experience a net downward force – and it will continue to accelerate downwards.

## Is a book sitting on a table an example of Newton’s third law of motion?

DESCRIPTION: A set of mathematics problems dealing with Newton’s Laws of Motion. The book lying on the table is exerting a downward force on the table, while the table is exerting an upward reaction force on the book. Because the forces are equal and opposite, the book remains at rest.
