   Normal Force. Weight (also called force of gravity) is a pervasive force that acts at all times and must be counteracted to keep an object from falling. You definitely notice that you must support the weight of a heavy object by pushing up on it when you hold it stationary, as illustrated in Figure(a).

   Mar 12, 2024 · The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity. The acceleration due to gravity is constant, which means we can apply the kinematics equations to any falling object where air resistance and friction are negligible. This opens a ...

   What is a force in physics?

   • is a push or a pull that acts on an object. There are two types of forces: or non-contact force - objects do not have to touch each other to exert a force. Force is measured in newtons (N). can be calculated. The size and direction of the resultant force enables us to describe how the motion of the object changes.

   Why does the weight of an object remain constant during a fall?

   • The weight of the object remains constant throughout the fall. The weight of the object is the force due to the mass being acted on by Earth's gravity. The air resistance is a frictional force which acts against the movement of the object. However, if an object is falling in a vacuum there is no air resistance.

   Can a normal force be less than the object's weight?

   • The normal force can be less than the object’s weight if the object is on an incline, as you will see in the next example. In this section we have introduced the quantity normal force, which is represented by the variable \ (\mathbf {ext {N}}\). This should not be confused with the symbol for the newton, which is also represented by the letter N.

   What happens if an object falls without air resistance or friction?

   • For the ideal situations of these first few chapters, an object falling without air resistance or friction is defined to be in free-fall. The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity.

   What is an example of a force?

   • A force is a push or a pull. For example, when you push open a door you must apply a force to the door. You also must apply a force to pull open a drawer. You cannot see a force but often you can see what it does. When a force is exerted on an object, it can: Forces can be contact forces, where objects must touch each other to exert a force.
