What happens to an object surface area as it is cut into pieces?
The object's surface area increases as extra surface which was before part of the inside of the object is exposed. If you found my answer helpful then please click recommend contributor :)
How mass affect surface area?
Mass does not directly affect surface area. Surface area is a measure of the total area of an object's external surfaces, while mass is a measure of the amount of matter in an object. However, as the mass of an object increases, its volume typically increases as well, which can indirectly affect its surface area if the shape remains constant. Objects with larger masses may have larger surface areas if their volume increases proportionally.
Is surface area an extensive property?
Yes, surface area is considered an extensive property because it depends on the amount of material or the size of the object. As the size of an object increases, its surface area also increases. Extensive properties, like mass and volume, change with the quantity of the substance, distinguishing them from intensive properties, which remain constant regardless of size.
What is the difference between surface area and radius?
surface area is the area of a 3D object radius is half of the diameter of a circle
What are the advantages of higher proportion of surface area to volume?
- A higher surface area will increase heat loss as more heat can be radiated. - It may improve an object's ability to float on water. - Increases drag or air resistance when an object is moving - this is why parachutes are used to slow people down when falling.
Why contact force between surface increases when speed increases?
As the speed increases, the force of contact between the surface and the object increases because the object has more momentum and exerts a greater impact force on the surface. This is due to a combination of factors such as momentum transfer, friction, and surface deformation, leading to an increase in the contact force.
Which type of friction exists between a surface and moving air?
The type of friction that exists between a surface and moving air is called air resistance or drag. This friction force opposes the motion of the object through the air and increases as the speed of the object increases. It is influenced by factors such as the shape and surface area of the object, as well as the speed at which it is moving.
Sliding friction increases if the of the sliding object increases.?
Surface area
Why objects move slowly on rough surfaces?
Objects move slowly on rough surfaces because there is more friction between the object and the surface. The rough surface increases the contact area between the object and the surface, which creates more resistance to motion. This frictional force slows down the movement of the object.
Investigate-how friction increases with increase of size of an object?
The force of friction on an object is equal to the coefficient of friction times the force perpendicular to the surface (normal force). When the mass of an object increases, the normal force increases, and the force of friction also increases. However, because the equation does not involve surface area, increasing surface area has no affect on the force of friction.
What is the link between air resistance and surface area?
Air resistance is directly proportional to the surface area of an object. As the surface area of an object increases, there is more contact with air molecules, resulting in greater air resistance. This resistance can affect the speed and motion of the object.
Why does the friction increase when the slope increases?
Friction increases on a slope because the gravitational force component pulling the object downhill adds to the normal force pushing it into the surface. This increased normal force results in higher friction between the object and the surface, making it harder for the object to slide or roll down the slope.
What are facts about static friction?
Static friction is the force that must be overcome to start an object moving on a surface. It increases as the normal force between the object and the surface increases. The maximum static friction force is proportional to the normal force and can vary depending on the types of materials in contact.
What is the relationship between height and potential energy?
The relationship between height and potential energy is that the potential energy of an object increases as its height above the ground increases. This is because the higher an object is lifted, the more gravitational potential energy it has due to its increased distance from the Earth's surface.

What happens to friction if the weight of an object is increased?
If the weight of an object is increased, the friction between the object and the surface it's resting on also increases. This is because the force pressing the object against the surface is greater, resulting in more resistance to motion.
How does pressure exerted by a solid object?
Pressure exerted by a solid object is calculated by dividing the force exerted by the object over the surface area on which it is applied. The formula is pressure = force / area. The pressure increases as the force increases or the surface area decreases.
