Calculating the velocity of an object falling due to gravity is a complicated process because gravity decreases the further above the Earth you go. There is also a terminal velocity because of the viscosity of the air.

Simply though, acceleration due to gravity at the Earth's surface is roughly 9.8m/s2. This means, after 1 second, an object will have achieved a velocity of 9.8m/s.

The equation then if the viscosity of air and height above the Earth's surface are ignored is

V = 9.8 x S

Where V is the velocity and S is the number of seconds it has been falling.

How to calculate velocity after collision in a physics experiment?

To calculate velocity after a collision in a physics experiment, you can use the conservation of momentum principle. This involves adding the momentum of the objects before the collision and setting it equal to the momentum of the objects after the collision. By solving this equation, you can determine the velocity of the objects after the collision.


What is the hypothesis of how does air resistance affect the velocity of falling objects?

The object opposes the air and while falling of the object the initial velocity will become zero , and the final velocity will have some value's this is how air will resist the velocity of falling object ...........


How can you calculate the velocity and acceleration of falling objects?

Acceleration:Always the same, doesn't need to be calculated. Acceleration of gravity = 9.8 meters (32.2 ft) per second2Acceleration of gravity is negative (points down).Velocity:(Initial velocity) + [ (acceleration) x (time) ]Positive velocity = moving upNegative velocity = moving down


How do you find the total time that on object is in the air with an initial velocity?

You can use the equation v = u + at from kinematics v = final velocity, which in this case is 0 because the object eventually hits the floor. u = initial velocity which is given to you a = acceleration which is always 9.8m/s^2 when dealing with falling objects t = time. manouver the equation and solve for time. Keep in mind that I havn't taken into account movement in the x-y direction and assumed that it is just a falling object falling in the -y direction. CG


When the only force acting on a falling object is gravity the objects is said to be?

The speed when falling objects no longer accelerates due to air resistance is?

known as terminal velocity, which is reached when the force of gravity pulling the object downwards is balanced by the upward force of air resistance. At terminal velocity, the object falls at a constant speed with no further acceleration.


What causes falling objects to reach top velocity?

Falling objects reach top velocity due to the acceleration of gravity pulling them downwards. As the object falls, the force of gravity causes it to accelerate until air resistance (or another opposing force) balances out the acceleration, leading to a constant velocity known as terminal velocity.


What is the circular orbit equation used to calculate the motion of objects in a circular path?

The circular orbit equation used to calculate the motion of objects in a circular path is called the centripetal force equation, which is F mv2/r.


When gravitational forces and air resistance equalize on an object that is falling toward earth and the objects stop accelerating its velocity is called the?

terminal velocity


What is the speed limit of falling objects called?

The speed limit of falling objects is called terminal velocity. This is the constant speed that a freely falling object eventually reaches when the resistance of the medium it is falling through (like air) equals the force of gravity acting on it.


How does air resistance affect the velocity of falling objects?

Slows an object down or speeds one up.


How do you calculate common velocity after collision?

To calculate the common velocity after a collision, you can use the principle of conservation of momentum. For two objects colliding, the total momentum before the collision equals the total momentum after the collision. The formula is given by: ( m_1 v_1 + m_2 v_2 = (m_1 + m_2) v_f ), where ( m_1 ) and ( m_2 ) are the masses of the two objects, ( v_1 ) and ( v_2 ) are their velocities before the collision, and ( v_f ) is the common velocity after the collision. Rearranging this equation allows you to solve for ( v_f ).
