What is the surface of an object?
surface area
An object with a large surface area has what air resistance?
An object with a large surface area experiences greater air resistance because there is more surface for the air to push against as the object moves. This can slow down the object's motion more significantly compared to an object with a smaller surface area.
Is greater force needed to move an object over a smooth surface than over a rough surface?
No, greater force is typically needed to move an object over a rough surface compared to a smooth surface. This is because the irregularities on a rough surface create more friction, making it harder to overcome resistance and move the object. Smooth surfaces offer less resistance to movement.
Why does an object take longer to slow down on a slippery surface?
On a slippery surface, there is less friction between the object and the surface, which reduces the force acting against the object's motion. This means that it takes longer for the object to decelerate and come to a stop compared to a surface with more friction.
What happens when an object is put above a rough surface and then suddenly yank it?
When an object is yanked from above a rough surface, the friction between the object and the surface will resist the motion, causing the object to slow down and possibly slide or tumble. If the force applied is strong enough to overcome the friction, the object will accelerate in the direction of the force until it is released.

What is surface area and how you can decrease or increase surface area?
Surface area refers to the total area that covers the surface of an object or structure. To decrease surface area, you can reduce the dimensions of the object or change its shape to be more compact. To increase surface area, you can add extensions, rough textures, or indentations to the object's surface.

What is the object of the preposition in the sentence you can stay here under the covers?
The object of the preposition "under" is "covers," as it is the noun that the preposition is referring to in relation to the verb "stay."
Why does a moving object eventually come to a stop on a frictional surface?
A moving object eventually comes to a stop on a frictional surface because the friction between the object and the surface creates a force that opposes the object's motion, gradually slowing it down until it stops.
Why does a large object absorb and emit radiation faster than a small object?
A large object has a greater surface area, allowing it to absorb and emit radiation at a faster rate compared to a smaller object. This is because the larger surface area provides more contact points for radiation to be absorbed and emitted.
What is total surface occupied by an object?
The total surface occupied by an object refers to the area that covers its outer surface. This measurement is typically expressed in square units, such as square meters or square inches. It encompasses all the faces or surfaces of the object, providing a comprehensive understanding of how much space the object occupies externally. This concept is crucial in various fields, including geometry, architecture, and material science.
What determines whether an object falls to Earth's surface or orbits Earth?
The object's initial velocity and height above the Earth's surface determine whether it falls to the Earth's surface or stays in orbit. If the object's initial velocity is high enough and directed perpendicular to the surface, it can enter orbit around the Earth. If the velocity is too low or the object is at a low enough height, it will fall towards the Earth's surface.
