What else can I help you with?
Do velocity vectors combine with force vectors?
simply: No, Velocity vectors are different to force vectors. One measures velocity and one measures force so you can not simply add/subtract/multiply/divide them together and get something meaningful.
When two pr more vectors act on an object they act independently of one another?
When multiple vectors act on an object, each vector exerts its own force on the object independently of the others. The resultant force is the vector sum of all the individual forces acting on the object.
When two or more vectors act on an object they act independently of one another?
When two or more vectors act on an object, the total effect is the vector sum of each individual vector. This is known as the principle of superposition. The resulting displacement or force on the object is determined by adding the magnitudes and directions of each vector.
What is the resultant force if the first force has an upward vector and the second force has a downward vector?
If the two vectors are directly opposite each other, then subtract the smaller one from the larger one and that will be your resultant force. For example, if the force downwards is 5 N and the force upwards is 2 N, the resultant force is 3 N downwards. If the one or both of the two vectors are angled, you need to replace the angled vectors with two right-angled vectors and then add those to create the resultant vectors.
What is the relationship between an object's acceleration and the direction of the force on the object?
If an object is increasing in speed, the acceleration is positive and the force is in the direction of travel. If the object is slowing down, the acceleration is negative and the force is acting against the direction of movement.

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:

When two or more vectors act on an object, the total effect is the vector sum of each individual vector. This is known as the principle of superposition. The resulting displacement or force on the object is determined by adding the magnitudes and directions of each vector.
What is the resultant force if the first force has an upward vector and the second force has a downward vector?
If the two vectors are directly opposite each other, then subtract the smaller one from the larger one and that will be your resultant force. For example, if the force downwards is 5 N and the force upwards is 2 N, the resultant force is 3 N downwards. If the one or both of the two vectors are angled, you need to replace the angled vectors with two right-angled vectors and then add those to create the resultant vectors.
How do you calculate magnitude and direction of one object being pushed by two different forces in two different directions?
each force itself is a vector quantity, so in order to determine the net force on an object, you need to add those vectors together either using law of cosines, or breaking the vectors to its i and j components. after doing so you will end up with a new vector, which is the sum of two other vectors. the new vector will have both new magnitude and direction.
What is the relationship between an object's acceleration and the direction of the force on the object?
If an object is increasing in speed, the acceleration is positive and the force is in the direction of travel. If the object is slowing down, the acceleration is negative and the force is acting against the direction of movement.
When one object applies a force to a second we call this force the?
When one object applies a force to a second object, we call this force the action force.
Example of force that moves but does no work?
work = force . distance. Since Force and distance are both vectors (work is the dot product), when the net distance = 0 (back to the point of origin), work = 0. That is, if the force is such that it moves the object back to the point of origin, it has done zero work. A centripetal force is one example. The distance = 0 when the object finishes one complete revolution. No work has been done since the beginning of the revolution.
Is push or pull that one object exerts off another?
A push is a force applied by one object on another in the direction away from the object exerting the force. A pull is a force applied by one object on another in the direction towards the object exerting the force.
Are vectors and scalars the same?
No, scalars and vectors are not the same. Scalars are measurements in numbers. Examples: work, energy, mass, speed, and distance. Scalars measure in one magnitude. Vectors measure velocity, acceleration, force, and momentum.
When one object applies force to the second object that force is called what?
The force applied by one object to another object is called an external force. This force can cause the second object to move, accelerate, deform, or experience other changes in its motion or shape.
