What is a single force that has the combined effect of all the forces acting on an object called?
Resultant
Similarity between balanced and unbalanced forces?
If the vector sum of forces on an object is zero, the forces are said to be balanced. Otherwise they are said to be unbalanced. Unbalanced forces will cause an acceleration, according to Newton's Second Law (a = F/m, where F is the net force, that is, the vector sum of all forces acting on the object).
What are the similarities between balanced and unbalanced forces?
An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.
Proof of parallelogram law of forces?
The parallelogram law states that when two concurrent forces F1 &F2 acting on a body are represented by two adjacent sides of a parallelogram the diagonal passing through their point of concurrency represents the resultant force R in magnitude and direction
What are the conditions of lami's theorem?
Lami's theorem states that if three forces are in static equilibrium, then the magnitude of each force is proportional to the sine of the angle between the other two forces. Since the forces are in static equilibrium, they sum to zero. This means that if the force vectors are put end-to-end, they form a triangle. The "law of sines" applies to any triangle, and states that the length of each side is proportional to the sine of the opposite angle. Interpreting the sides as force vectors, we get a statement of Lami's theorem.
A crate is at rest on the ground what force or forces are acting on the crate?
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
What do you have to do get forces acting on an object to get you net force?
a girl and a boy are pulling heavy crate at the same time with 10 units of force each . what is the net force acting on ythe object?
If balanced forces are acting on an object it will seem as if a net force is acting on the object?
If the forces are balanced this means that there is no net force acting
Pull horizontally on a crate with a force of 140 N and it slides across the floor in a dynamic equilibrium How much friction is acting on the crate?
If the crate isn't accelerating ... i.e. sliding at a constant speed, not speeding up or slowing down ...then the forces on it are balanced. The pseudo-force of friction is 140N in the direction opposite toits speed.
The is the combination of all forces acting on an object?
that is called the net force; it is a vector sum of all the forces acting on it
Are the force acting on the pen?
Yes there are forces acting on a pen.
If the net force On an an object is zero what do you know about all of the forces acting on the object?
Net force is a combination of all the foces acting on an object.If two forces are acting in the same direction you add the forces to calculate the net force
A crate remains at rest on a factory floor while you push on it with a horizontal force F How big is the friction force exerted on the crate by the floor?
Friction force = -F The crate is at rest, so all forces must be balanced
What is the combined total of all forces acting on an object?
that is called the net force; it is a vector sum of all the forces acting on it
when all of the forces on an object cancel one another out the forces are?
When the 'net' force on an object is zero, then either there are no forces acting on it, or else all the forces acting on it are 'balanced', and they have the same effect on it as if there were no force.
What are structures acting on forces?
Gravity is a force acting down on it. A normal force is acting perpendicular to the ground at the base of the structure.
