When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
How does liquid soap affect the surface tension of water?
it affects the surface tension because of its temperture
What physical factors control the rate of chemical reactions?
Physical factors that control the rate of chemical reactions include temperature, pressure, concentration of reactants, and surface area of the reactants. Temperature influences the kinetic energy of particles, pressure affects the collision frequency of molecules, concentration determines the number of reactive collisions, and surface area determines the contact area between reactants.
How does an active volcano effect earths surface?
an active volcano affects the surface because of where the place is located
How does surface tension influence your daily life?
Surface tension plays a crucial role in everyday activities, such as the ability of water to form droplets and the way it interacts with various surfaces. For example, it allows insects like water striders to walk on water without sinking. In cooking, surface tension affects how liquids behave, influencing the way ingredients combine and react. Additionally, surface tension is important in processes like cleaning, where it impacts the effectiveness of soaps and detergents.
Is Kinetic friction is affected by the weight of the object?
Kinetic friction is independent of the weight of the object. It is determined by the nature of the surfaces in contact and the force pressing them together. The weight of the object affects the normal force, which in turn affects the frictional force, but the coefficient of kinetic friction remains constant for a given surface.
What is the term for microscopic scratches on the surface of bullets?
ballistics
What is kinetic energy in chemistry?
In chemistry, kinetic energy refers to the energy associated with the movement of particles. It is related to temperature, with higher temperatures leading to greater kinetic energy and faster particle movement. This energy is important in chemical reactions as it affects the rate at which reactions occur.
When an object rolls across a surface?
When an object rolls across a surface, its kinetic energy is a combination of translational and rotational kinetic energy. The object's centre of mass moves in translational motion while it also undergoes rotational motion about its axis, resulting in a combination of both types of energy. Friction between the object and the surface affects its rolling motion by either slowing it down or aiding it, depending on the direction of the forces involved.
When an electron is ejected from the surface what type of energy does the electron possess?
The ejected electron possesses kinetic energy as it moves away from the surface.
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
What role does texture play in determining the effectiveness of primer?
Texture plays a crucial role in determining the effectiveness of primer because it affects how well the primer adheres to the surface. A smooth texture allows the primer to create a strong bond with the surface, ensuring better coverage and durability. On the other hand, a rough texture may prevent the primer from adhering properly, leading to poor coverage and potential issues with the paint job.
What causes particals to evaporate and leave the surface of a liquid?
Molecules at the surface of a liquid absorb kinetic energy (kinetic energy used to disrupt intermolecular forces) and evaporate. (vapor pressure is exerted)
Why kinetic friction is less than sliding friction?
there is more surface area contact with kinetic friction as opposed to sliding friction
How the surface temperature affects the year?
The time of year it happens to be affects the temperature not the other way round.
Where does kinetic energy go when a marble stops?
When a marble stops moving, its kinetic energy is converted into other forms of energy such as sound and heat due to friction with the surface it stops on. Some of the kinetic energy may also be transferred to the surface of the marble and the surrounding air molecules as vibrations.
Why evaporation is called a surface phenomenon?
Evaporation can only take place on the surface of liquids because that is where the molecules with the highest kinetic are found. Only molecules with high kinetic energy are free to escape into the atmosphere.
