What else can I help you with?
What do you get when you subtract the force of air resitance from the force of gravity?
First of all, gravity is not a force, it is an acceleration. What you mean is the force of weight, which is the acceleration of gravity multiplied by mass (all forces are vectors, and gravity is not a vector.) When air resistance is subtracted from weight, you have the net force on a falling object (assuming those are the only forces acting on it.)
When can forces be added together to find the net force upon an object?
Yes, when all the forces acting on a body have been resolved, the final force is known as the 'net force' acting on that body.
What does it mean that forces can be added or subtracted?
Forces can be added or subtracted when they act in the same or opposite directions, respectively, on an object. When forces are added, their magnitudes combine to produce a net force on the object. When forces are subtracted, their magnitudes are compared to determine the resultant force acting on the object.
When are force said to be added and when are they subtracted?
if two forces act in same direction they r added and if they act in opposite direction they r subtracted
What are the arrows called on a force diagram?
The arrows on a force diagram are called vectors. Vectors represent the magnitude and direction of a force acting on an object. The length of the arrow corresponds to the strength of the force, and the direction of the arrow indicates the direction in which the force is acting.
Is force a vector quantity if so why?
Yes, force is a vector quantity, because it is exerted in a specific direction (even in the case of a symmetrical explosion, in which force is exerted in all directions, that is still a type of vector).
What are the good and bad things about vector?
Good: Vectors are versatile and can represent quantities such as force, velocity, and acceleration with both magnitude and direction. They can be added and subtracted geometrically. Bad: Vectors can be complex to work with in higher dimensions, and their geometric representation may not always translate well into numerical computations. Understanding vector operations and their properties can require a solid mathematical foundation.
What is the sum of to vectors?
A variety of mathematical operations can be performed with and upon vectors. One such operation is the addition of vectors. Two vectors can be added together to determine the result (or resultant). This process of adding two or more vectors has already been discussed in an earlier unit. Recall in our discussion of Newton's laws of motion, that the net force experienced by an object was determined by computing the vector sum of all the individual forces acting upon that object. That is the net force was the result (or resultant) of adding up all the force vectors. During that unit, the rules for summing vectors (such as force vectors) were kept relatively simple. Observe the following summations of two force vectors:
Can velocity vectors be combined with force vectors?
No
What is muscle force and its vector representation?
Muscle force is the force produced by the contraction of a muscle. Force vectors, torque vectors, and difference vectors can all be used to help describe this force.
What is the difference between a ray and a vector in terms of their properties and applications in mathematics and physics?
A ray is a line that starts at a point and extends infinitely in one direction, while a vector has both magnitude and direction. In mathematics, rays are used to represent lines in geometry, while vectors are used to represent quantities like force or velocity in physics. Vectors can be added and subtracted, while rays cannot.
When two forces act on the same object in opposite directions is the smaller force subtracted from the larger force?
yes, result is called the net force
