Which Condition Describes an Object Having Terminal Velocity

- April 13, 2022

The force of air resistance is approximately proportional to the speed of the falling object so that air resistance increases for an object that is accelerating having been dropped from rest until terminal. The velocity of a falling object when its weight is balanced by the sum of the drag and upthrust acting on it.

Object A has a velocity of 10 ms and an acceleration of 0 ms2 when it passes object B which is rest at the origin at t 0 s.

. Eventually reach terminal velocity. When the object starts its fall the speed is zero v0 so only gravity acts and it accelerates the object downward. Because model rockets do not fly very high the air density is nearly constant.

The constant velocity is called the terminal velocity. 3 on a question Which condition describes an object having terminal velocity. Using algebra we can determine the value of the terminal velocity.

Hopefully this helps. Which condition describes an object having terminal velocity. Terminal velocity is defined as the highest velocity that can be achieved by an object that is falling through a fluid such as air or water.

At terminal velocity. The formula is that you have to divide the distance by the time it takes you to travel that same exact distance then you have to add your direction. - Momentum of ball 1.

Cd r V 2 A 2 W. Vt 2W ρACd where W is the weight of the object ρ is density of the fluid A is the projected frontal area and Cd is the drag coefficient which depends. The terminal velocity is not only dependent on the speed of an object but also the density of the fluid through which the object moves the cross sectional area presented by the moving object and a drag coefficient.

If object B has an acceleration of 2 ms2 and starts moving the instant object A passes it which object crosses the finish line at x 100 m first. Answered 2 years ago Author has 49K answers and 7M answer views. Correct answer to the question Which condition describes an object having terminal velocity.

When this occurs the acceleration of the object becomes zero because forces are balanced. Where r is the radius of the sphere m v is the velocity of the sphere m s-1 η is the viscosity of the fluid Pa s. The condition of a falling object in which the upward air resistance acting on the object is equal in magnitude to the downward weight force.

Objects A and B both move with constant acceleration along the x-axis. An object at terminal velocity has zero net acceleration. The quotient of three times some number and five the product of some number and five divided by three the quotient of three and some number times five the sum of three and some number divided by five.

With no acceleration the object falls at a constant velocity as described by Newtons first law of motion. Definition of Terminal Velocity. Objects falling through a fluid.

Big rain drops fall faster than small rain drops. Therefore the speed of the object increases and so does the air resistance until a point where the air resistance becomes equal to gravity which is constant. Gravity air resistance b.

Specifically the terminal velocity is proportional to the square root of the diameter of the drop. The object then falls at a constant velocity as described by Newtons first law of motion. The constant vertical velocity is called the terminal velocity.

So the total momentum after the collision will also be zero. V sqrt 2 W Cd r A Typical values of the drag coefficient are given on a separate slide. The net force on the falling object is zero the object is in equilibrium the downward velocity is.

The cross sectional area is the area cutting across the object in a plane. But if youre talking about what determines an objects Terminal velocity then. ExplanationWhen drag is equal to weight there is no net external force on the object and the acceleration becomes zero.

So the total momentum is. Terminal velocity is achieved therefore when the speed of a moving object is no longer increasing or decreasing. Formula for Stokes Law.

Speed and Direction determines an objects velocity. The velocity of the oscillating mass can be found by calculating the derivative of the position. Which verbal expression best describes the algebraic expression 3x 5.

When terminal velocity is reached the downward force of gravity is equal to the sum of the objects buoyancy and the drag force. At terminal velocity the object moves at a steady speed in a constant direction because the resultant force acting on it is. Different objects would have different terminal speeds.

Gravity air resistance gravity air resistance gravity air resistance. The objects acceleration or deceleration is zero. - Momentum of ball 2.

Which condition describes an object having terminal velocity. And thats why the formula for velocity is similar to speed. Gravity air resistance c.

Correct answer to the question Which condition describes an object having terminal velocity. For a model rocket the value is near 075. Solving for the vertical velocity V we obtain the equation.

Assuming north as positive direction we have.
