What are two factors that affect friction?
The friction force depends on two factors:
- a) The materials that are in contact. The two materials and the nature of their surfaces.
- b) The force pushing the two surfaces together. Pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other.
What are the two factors on which the force of friction depends Class 8?
Friction depends on two factors: (i) Nature of the surfaces in contact i.e. whether surface is rough or smooth. Friction depends on the smoothness or roughness of the two surfaces which are in contact. A rough surface produces greater friction as compared to a smooth surface.
What are the two factors that determine the strength of the force of friction?
The strength of the force of friction depends on two factors; the type of surfaces involves and how hard the surfaces push together, What is one way you could reduce the friction between two surfaces? Ball bearing are one way of reducing friction between two surfaces.
What is a force and what are the factors that determine its effect?
Two major factors, mass and distance, affect the strength of gravitational force on an object.
What two factors describe force?
Answer: To fully describe the force acting upon an object, you must describe both the magnitude (size or numerical value) and the direction.
What are the two factors that affect the magnitude of force?
Factors that affect the magnitude of the force The angle between the conductor and the external magnetic field. This is what determines the conductor’s effective length, or the vertical component of the length.
What are the four factors that affect the magnitude of the force?
1) Strength of Magnetic fields = force is directly proportional to strength of Magnetic fields. 2) Strength of Electric field = force is directly proportional to strength of Magnetic fields. 3) Length of conductor = force is directly proportional to length of Magnetic fields.
What are the factors affecting the magnitude of force?
Factors Affecting the Magnitude of the Force on a Current Carrying Conductor. (a) The current in the conductor, (b) The strength of the magnetic field. A larger current in the conductor will result in a larger force acting on it if the strength of the magnetic field is kept constant, as shown in Figure.
Which factors affect the magnitude of the Lorentz force?
The direction of the electric field. The velocity of the moving particle. The strength of the magnetic field. The strength of the electric field.
Which of the following factors affect the strength of force experience by a current?
Force experienced by a current carrying conductor placed in a uniform magnetic field depends on the following factors: i) Magnetic field strength. ii) Current through the conductor. iii) Length of the conductor.
What are the various factors affecting the magnetic effect of electricity?
Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core.
Where is the magnetic effect of current used?
When current flows in conductor, it behaves as temporary magnet due to its magnetic effect, this type of magnet are termed as electromagnet and electric motor is used torque due to current in magnetic field . Bulb uses heat energy due to current.
What is meant by magnetic effect of current?
1. The term ‘magnetic effect of electric current’ means that an electric current flowing in a wire produces a magnetic field around it . Magnetic field is a quantity that has both magnitude and direction ; as such it is a vector quantity.
What is the meaning of effect of current?
When the current is passed through an electric circuit it produces some magnetism which can be detected with the deflection in compass needle. this phenomena is known as magnetic effect of electric current.
