How would the terminal velocity of an object falling towards earth differ than the terminal velocity of the same object falling through water?

because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity

How will the upward force of air resistance compare to the downwward pull of gravity?
Assuming that you're referring to an object that is accelerating towards a massive body by means of gravitational attraction... When the force of frictional air resistance equals the opposing force of gravity, the net force on the object equals zero, and acceleration will cease. It is called terminal velocity, and the object will remain at this velocity until some new event happens.
If the gravitational pull of the sun is the most then why doesn't it pull the planets towards it?
It does. The planets have velocity and inertia that keep them in orbit; but they really ARE continuously falling towards the Sun, their velocity makes them miss it constantly though!
What is the relationship between air resistance and the acceleration of falling objects?
As an object falls towards the earth, it accelerates due to the force of gravity acting on it's mass. As velocity increases, air resistance increases. This is in the opposite direction to the force of gravity on the object. Therefore the resultant force on the object is decreased, and the rate of acceleration is reduced. Eventually, the force due to the air resistance is equal in magnitude to the weight and the object has no resultant force acting. At this point the object will be travelling at a constant velocity, commonly referred to as Terminal Velocity.
What causes a satellite to stay in orbit rather than falling towards earth?
Its forward motion. Please understand that something in orbit IS falling towards Earth.
The displacement time graph of a body is ll to time axis what will you infer about the velocity of the body?
That the component of the velocity towards or away from the origin is zero. You can infer nothing at all about its overall velocity since it could be travelling in a transverse direction at any velocity.
What is terminal velocity and how to control it and why it occurs?
Terminal velocity is when air resistance balances out with gravity. For humans it's usually around 2000 ft of falling, gravity accelerates the person towards the ground at about 9.8m/s, as said person speeds up, air resistance increases and it becomes harder to accelerate. Terminal velocity is the point at which one may no longer accelerate. To control it: more air resistance = slower descent (terminal velocity comes sooner and is not as fast (i.e.parachutes), less air resistance = faster descent, it may take longer to reach terminal velocity as it is a much higher speed.

How do things accelerate when there is no air present?
Air is not a requirement for acceleration. Objects in the vacuum of space accelerate to other objects under the force of gravitational attraction. Rockets are propelled by escaping gases in the same manner as you are accelerated in the opposite direction when you throw an object while you are sitting on a rolling chair.Answer:Let's look at the case of an object falling from a great height towards the Earth.Once the object is released it accelerates towards the Earth due to gravity at 32ft/sec/sec. The acceleration continues until the force required to push through the air balances the force of gravity . This is known as terminal velocity.Now lets consider an airless planet the same size as Earth (to make the attraction of gravity the same). We drop the body from the same height over its surface, it accelerates downward, but does not have to push air out of the way. There is no terminal velocity ands its speed continues to increase all the way to the ground.Thus bodies falling through a gas accelerate until terminal velocity is reached, bodies falling in a vacuum continue to accelerate.
A satellite in orbit around earth is always falling towards earth?
Yes. They accelerate (change the direction of their movement) towards Earth, and this may be labelled as "falling".Yes.

How gravity and air resistance are related to an object's terminal velocity?
Gravity and air resistance (drag) are the two opposing forces acting on the falling body. Gravity causes the object to accelerate (fall faster) while the air resistance causes the object to decelerate (fall slower). At a certain velocity called the terminal velocity these two forces are in balance and there is no change in falling speed.
How is a satellite held in its orbit around earth?
Gravity and velocity vectors in the proper ratio combine to make a state of perpetual falling towards the Earth that always misses
What happens as an object falls towards the earth?
It accelerates downward at a rate of 9.8m/s2. Depending on the object and how high above the earth it started, it may reach terminal velocity at which point it will no longer accelerate, but will continue to fall at a constant velocity.
Explain the term terminal velocity?
The point at which the acceleration due to gravity is equal to the friction of the air dragging on the object (generally). When the two are equal, they cancel out and no more acceleration occurs, causing the object to have attained the fastest speed possible.
What is the relationship between air resistance and the acceleration of falling objects?
As an object falls towards the earth, it accelerates due to the force of gravity acting on it's mass. As velocity increases, air resistance increases. This is in the opposite direction to the force of gravity on the object. Therefore the resultant force on the object is decreased, and the rate of acceleration is reduced. Eventually, the force due to the air resistance is equal in magnitude to the weight and the object has no resultant force acting. At this point the object will be travelling at a constant velocity, commonly referred to as Terminal Velocity.
Why velocity of flow will decrease with increase in peripheral speed of francis turbine?
the peripheral velocity of the turbine is the around velocity. the increase in the velocity of the peripheral will decrease the velocity of the flow towards the turbine
On a 1993 Ford Ranger 3.0 which terminal on distributor cap is 1?
The # 1 terminal should have a 1 marked beside it. It is at the back , towards the firewall and towards the passenger side of the motor
