The forces are vectors, the vectors are added together, therefore forces acting against each other will cancel each other out, forces acting in the same direction will add up.
For forces acting in different directions you can use Pythagorean theorem to add them up.
The sum is what gives the body an acceleration, depending on it's mass. ( F=m*a )
What else can I help you with?
Can a force acting perpendicular on a body cancal a force which is acting horizontally on the same body?
Yes, a force acting perpendicular to a horizontal force on a body can cancel out the horizontal force if the two forces are equal in magnitude and opposite in direction. This is known as the equilibrium condition, where the net force acting on the body is zero.
If a crate is stationary on an incline does it mean that it is in the state of equilibrium?
If a crate placed on an inclined plane is moving at constant velocity or not moving at all -- which is really a special case of constant velocity where the velocity is zero -- then the sum of the forces acting upon it is zero. We can say that it is in a state of equilibrium, where all forces acting upon it are in perfect balance and cancel themselves out. A free-body diagram is often used to represent a body and the forces acting upon it and helps us visualize the relationship of the vector forces. See this link: http://en.wikipedia.org/wiki/Free-body_diagram#Example
Explain why the polygon of forces must close when a body is in equilibrium?
The answer is in the definition: polygon of forces(plural polygons of forces) # (mechanics) A polygonal figure the sides of which are vectors representing several forces acting simultaneously upon one point, so that the vector necessary to make the figure closed is the resultant of those forces.
Can a acceleration be zero while several forces are acting on the body?
Yes, if all the forces vector sum to zero then there is no acceleration. For example if a you push on sled with 10 pounds and someone else pulls the other end with 10 pounds it does not move - no acceleartaion - net force is zero even though two forces are 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 is force acting on a body with uniform motion?
A body in uniform motion has no net force acting on it. That means that either there are no forces at all, or else that all the forces acting on it add up to zero.
What occurs when forces acting upon a body are not balance?
When forces acting on a body are unbalanced, the body will experience acceleration in the direction of the net force. This acceleration causes the body to change its velocity, resulting in motion. The body will continue to accelerate until the forces acting upon it become balanced.
What occurs forces acting upon a body are not balanced?
The body accelerates.
What are the forces acting on a roller coaster in a free body diagram?
In a free body diagram of a roller coaster, the forces acting on it are gravity, normal force, friction, and air resistance.
Is a body at equilibrium cannot be acted upon by external forces?
A body at equilibrium can still have external forces acting on it, but the net force acting on the body is zero. This means that the individual forces may cancel each other out, resulting in no acceleration or change in motion of the body.
What is net effect of two forces acting on a body?
Depe
When can a body stay at rest even though forces act on it?
A body can stay at rest even though forces act on it when the forces acting on the body are balanced, meaning they cancel each other out. This balance of forces results in no net force acting on the body, allowing it to remain at rest.
What are the force acting on a body at rest?
When a body is at rest, the forces acting on it are balanced. These can include gravitational force pulling the body downward and normal force exerted by the surface supporting the body. As long as these forces are equal and opposite, the body remains at rest.
How can free body diagrams be used to analyze the forces acting on an object?
Free body diagrams can be used to analyze the forces acting on an object by visually representing all the forces acting on the object as vectors. By isolating the object and showing the direction and magnitude of each force, free body diagrams help in understanding how the forces interact and affect the object's motion or equilibrium.
What is equilibrant forces?
The force is said to be "equilibrant" when acting with other forces it would keep the body at rest ie in equilibrium. Hence equilibrant would be equal in magnitude but opposite in direction to the resultant of all the forces acting on the body.
What Refers to the sum of all forces acting on the body?
Net force is the sum of all forces acting on a body. It is the overall force that influences the body's motion and determines its acceleration according to Newton's second law of motion.
Newton's laws of motion are deterministic.?
Yes, Newton's laws of motion describe the relationship between a body and the forces acting on it, providing a deterministic way to predict its motion based on initial conditions. This means that if the forces on a body are known, its future motion can be predicted precisely.
