Gravity and Resistance
Under free fall, the only force acting upon an object is the force of gravity. But realistically, there is also the force of friction from the air (Air Resistance) that opposes the force of gravity.
Large dense objects, and the closest objects.
The gravitational forces of the Sun and Moon, effect the earths oceans by forming tides.
The atmosphere affects objects by exerting pressure on them, causing drag and resistance. It can also cause objects to heat up or cool down depending on the conditions. Additionally, the atmosphere can impact the movement and behavior of objects through factors like wind and turbulence.
Yes, forces such as gravity still work in space. Objects in space are subject to gravitational forces from other objects, such as planets and stars. Additionally, forces can be generated by propulsion systems to move spacecraft and satellites in space.
All objects on Earth experience gravitational force to a certain degree. Earth's atmosphere grants it's objects a great gravitational force.+++"All objects throughout the Universe experience gravitational force... " Not just on Earth. The Earth's orbit around the Sun is a function of the Earth's velocity and the Sun's gravity.The Earth's atmosphere does NOT "grant" any gravitational force of its objects (whatever those may be), but is itself subject to the gravity of the planet; hence both it still being here, and exerting a mean pressure of I Bar (by definition) or 100kPa at sea-level.
Mainly gravity, and air resistance.
The two main forces acting on a falling object in Earth's atmosphere are gravity, which pulls the object downward, and air resistance (also known as drag), which opposes the object's motion and slows it down as it falls.
2 is the answer
falling objects.
GravityGravity is the attraction between two objects. Since the earth is huge we are attracted to the earth and so are most things that we live with today. There are certain gases that are not held by the earths gravity. These gases are very light and float out of the atmosphere. A balloon would be a good example... its filled with Helium.
The main forces acting on a falling object are gravity, which pulls the object downwards towards the center of the Earth, and air resistance, which opposes the motion of the object as it falls through the air.
False. Free falling objects accelerate at a rate of 9.8 m/s^2 due to the force of gravity acting on them. The force of friction and air resistance do not significantly affect the acceleration of free falling objects in a vacuum.
terminal velocity
Free falling objects are those that are only under the influence of gravity, with no other external forces acting on them. As a result, these objects accelerate towards the ground at a rate of 9.81 m/s² (on Earth) and do not experience air resistance. The motion of free falling objects can be described using the equations of motion.
On any planet with an atmosphere, gravity is counteracted by the force of air friction with the object that is falling. This is known as terminal velocity - the point at which the forces of air resistance and gravity balance.
Assuming you mean "falling": the main forces are gravity (downward), and friction (in the direction opposite to the object's movement - for example, if the objects falls straight down, that would be upward).
Exogenous forces are forces that work above the earths surface and break down landforms. Endogenous forces are forces that work below the earths surface and build up land forms
