What else can I help you with?
A magnetic field is described by magnetic lines of?
force that represent the direction in which a magnetic object would move if placed in the field. These lines form a pattern that helps to visualize the strength and direction of the magnetic field. The density of the lines indicates the strength of the magnetic field at a particular point.
How do you know that a force is negative or positive in relation to magnetic field?
It depends on what direction is considered positive and what direction is considered negative. For this case, I'll assume that up, right, and outward are positive and down, left, and inward are negative. Since the force is perpendicular to the magnetic field, the sign for the force depends on the direction of the current. If the current is inward and the magnetic field is to the left, then the force is upward and thus positive. If the current would be outward and the magnetic field would be still to the left, then the force is downward and thus is negative. The best way to think of this is to use the "right-hand" rule. Use your index finger to represent the direction of the current, your thumb as the direction of the force, and the other three fingers as the direction of the magnetic field direction.
What is it called when a force is equal in strength but opposite in direction to an action force?
It is called a reaction force. The question you have asked is paraphrase of Newton's third law of motion. Action and reaction are always equal but opposite in direction.
A fixed pulley changes the blank of a force?
changes the direction of a force
What are forces equal in strength but opposite in direction?
It happens when 1 force is having larger magnituge and the other is less in magnitude ........ and then the forces does not balance each other Take the example of weight and tension of a body connected by string . weight and tension are always opposite in the direction if the weight is suppose 12 newton and tension is 10 newton , then same thing will happen , they can't balance each other ...... as the strength of weight is more than tension
Can be used to represent the direction and strength of a force?
A vector can represent the direction and strength of a force.
What can be used to represent the strength and direction of a force?
A vector can represent the direction and strength of a force.
What can be used to represent the direction and strengh of a force?
A vector can be used to represent the direction and strength of a force. The magnitude of the force is indicated by the length of the vector and the direction of the force is represented by the orientation of the vector.
What can be used to respesent the direction and strenght of a force?
A vector can be used to represent the direction and strength of a force. Vectors have both magnitude (strength) and direction, making them ideal for representing forces in physics calculations and diagrams.
What do the length and direction of a force arrow represent?
The length of a force arrow represents the magnitude or strength of the force, with longer arrows indicating a stronger force. The direction of the force arrow represents the direction in which the force is being applied on an object.
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.
What do you need to represent a force graphically?
To represent a force graphically, you need to indicate the magnitude (strength) and direction of the force using a vector arrow. The length of the arrow corresponds to the magnitude of the force, and the direction of the arrow indicates the direction in which the force is acting. It is also helpful to include labels or coordinate axes to provide context for the force.
When an arrow is used to show a force what two things do the arrow about the force?
An arrow used to show a force indicates the direction of the force and its magnitude relative to other forces in the system. The length and direction of the arrow represent the strength and direction of the force, respectively.
How does an arrow represent a force vector?
An arrow represents a force vector by indicating the direction and magnitude of the force. The length and direction of the arrow correspond to the strength and direction of the force being applied. It provides a visual representation that helps in analyzing and understanding the effects of forces in a system.
A magnetic field is described by magnetic lines of?
force that represent the direction in which a magnetic object would move if placed in the field. These lines form a pattern that helps to visualize the strength and direction of the magnetic field. The density of the lines indicates the strength of the magnetic field at a particular point.
How do you indicate the direction and strength of a force?
The direction of a force can be indicated using arrows, with the length of the arrow representing the strength of the force. Alternatively, numerical values or angle measurements can be used to specify direction and magnitude.
Do force vectors have direction only?
No, force vectors have both magnitude (strength) and direction. The direction of a force vector indicates the way in which a force acts, while the magnitude represents the strength of the force. Both aspects are important when analyzing the effects of forces on objects.
