## Which object will reach terminal velocity first?

heavy objects will have a higher terminal velocity than light objects. (Why? It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.)

## What is the first derivative of velocity?

Summary

derivative | terminology | meaning |
---|---|---|

1 | velocity | rate-of-change of position |

2 | acceleration | rate of change of velocity |

3 | jerk | rate of change of acceleration |

4 | jounce (snap) | rate of change of jerk |

**Can a ball reach terminal velocity?**

After the ball has dropped about 100 meters (around 25-30 stories for a normal building), the force of air resistance becomes large enough to balance the force of gravity; at this point, the ball has reached its “terminal velocity”, and falls at a constant rate without further acceleration.

### How is terminal velocity derived?

Terminal Velocity in Presence of Buoyancy Force When this object has obtained terminal velocity, the object weight gets balanced by the force of upward buoyancy, and the drag force. This is represented by, W = Fb + D.

### What is the terminal velocity of a ball?

Terminal Velocity Examples

Falling object | Mass | Terminal velocity |
---|---|---|

Baseball (3.66cm radius) | 145 gm | 33 m/s |

Golf ball (2.1 cm radius) | 46 gm | 32 m/s |

Hail stone (0.5 cm radius) | .48 gm | 14 m/s |

Raindrop (0.2 cm radius) | .034 gm | 9 m/s |

**Which object will hit the ground first?**

heavier object

The force due to gravitation and air resistance. In the absence of air resistance, both heavy and the lighter object will hit the ground at the same time. If the air resistance is present, the air resistance will slow down the lighter object. Therefore the heavier object will hit the ground first.

#### What is the first derivative of acceleration?

As a vector, jerk j can be expressed as the first time derivative of acceleration, second time derivative of velocity, and third time derivative of position: are sometimes called jerk equations.

#### Why does a ball reach terminal velocity?

As it gains speed, the object’s weight stays the same but the air resistance on it increases. There is a resultant force acting downwards. Eventually, the object’s weight is balanced by the air resistance. There is no resultant force and the object reaches a steady speed – this is known as the terminal velocity.

**What is terminal velocity of a golf ball?**

33 m/s. 74 mi/hr. Golf ball (2.1 cm radius)

## What is terminal velocity derive expression for terminal velocity?

STATEMENT: # The maximum constant velocity acquired by a body while falling through a viscous medium is called its Terminal Velocity. # It is attained when force of resistance of a medium is equal and opposite to the force of gravity.

## What is terminal velocity derived from?

Terminal Velocity Derivation. Terminal velocity is defined as the highest velocity attained by an object that is falling through a fluid. It is observed when the sum of drag force and buoyancy is equal to the downward gravity force that is acting on the object. The acceleration of the object is zero as the net force acting on the object is zero.

**What is the velocity at the highest point of a ball?**

If a ball is thrown vertically upwards with an initial velocity V 0 then here is a set of formula for your quick reference. 1) Maximum height reached = H = V 02 / (2 g) 2) Velocity at the highest point = 0

### What is the final velocity when a ball is thrown upward?

The height where the velocity becomes zero which is the maximum height the ball went upward, say is H. And for this upward movement, the final velocity v2 is 0 because the ball has stopped at the end of this upward traversal. Why an object thrown upwards comes down after reaching a point?

### What is the initial-value problem for the velocity of the ball?

In particular, if a ball is thrown upward with an initial velocity of ft/s, then an initial-value problem that describes the velocity of the ball after seconds is given by This model assumes that the only force acting on the ball is gravity. Now we add to the problem by allowing for the possibility of air resistance acting on the ball.
