Weight Fg Since the book is not moving, the forces are equal and thus balanced. The other pair of forces is the book on the table and the table on the book. In both cases – no resultant force.
Q. What tool do you use to measure wind direction?
A wind vane is a tool that identifies the direction the wind is blowing.

Q. Are normal force and weight always equal?
The normal force is usually symbolized by N . In many cases the normal force is simply equal to the weight of an object, but that’s only when the normal force is the only thing counteracting the weight. The normal force is the force that would be measured by a scale placed between the objects in contact.
Q. What are two examples of unbalanced forces?
If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it. This is an example of unbalanced force.
Q. What is a balanced force example?
Examples of Balanced Force: A game of tug of war with equally matched teams on either side is an example of balanced force. In this, the rope does not move as equal and opposite force is applied from each side. The weight of the boat is balanced by the upthrust from water.
Q. Is there any force acting on an object kept on a table?
Yes. Friction force, force of gravity and push exerted by table on object.
Q. When your notebook is sitting on your table why is it not moving?
The table surface pushes the notebook from below and prevents it from falling. (This force is called the normal force.) Gravity, or a pull from Earth, keeps the notebook from floating in the air. You just studied 34 terms!
Q. What happens to a body in free fall in a vacuum?
Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (190 km/h or 118 mph) for a human skydiver.
