Does the velocity for each second of free fall increase decrease or stay the same?
Increase, because the most free fall the most velocity for second. :-) <3 Att: Alvaro y Luza (Pereira-Colombia)!
How is the acceleration of an object in free-fall related to the acceleration due to gravity?
The acceleration in free fall IS the acceleration due to gravity, since "free fall" is the assumption that no forces other than gravity act on the object.
What is the theory of the acceleration due to gravity?
During a fee fall, when there is no normal force to resist the force of gravity, the body's acceleration is the same as the force of gravity 9.8m/s-2
Why the acceleration is constant in free fall?
Because there is only gravitatinal acceleration
What is the rate of acceleration an object encounters in free fall?
acceleration encountered by an object in free fall is 'g' or 9.8 m/s2
What happens to the distance you fall during each second?
If you fall from a very considerable height then initially the distance that you fall will increase with each second that you fall. However, air resistance increases markedly with speed and this causes your acceleration to decrease so that you reach a maximum speed (terminal velocity)
Name the seven factors that determine whether supplies increase or decrease?
Supplies increase or decrease based on the availability of materials and the availability of suppliers. A fall in cost can also cause an increase in supply.
Why population increase and decrease?
Populations increase and decrease because people leave one country (emigration) and enter another (immigration). A rise or fall in either the birth rate or death rate in a country can also cause populations to increase or decrease.
When does a body has a positive acceleration during free fall?
When affected by gravity.
When earth angular velocity increase then gravitational acceleration increase?
Let's be very accurate when describing accelerations in this question. Consider a person at the equator. The gravitational force of attraction on him is constant whether or not the earth is rotating. This acceleration is called the acceleration due to gravity (ag) Now, since the earth is rotating about its axis, there has to be a centripetal force on the person. It is the gravitational force which provides the centripetal force. Thus, there is a centripetal acceleration on the person (ac) Finally, the rest of the gravitational force causes the person to accelerate towards earth. This is called the acceleration of free fall (af) This gives ag = ac + af ac is given by the equation: ac = w2r where w is the angular velocity and r is the radius of rotation If the angular velocity of the earth increases, centripetal acceleration will increase. af = ag - w2r Therefore, the acceleration of free fall will decrease.
How is free fall related to acceleration?
during free fall of body the gravity of earth tries to attract the body as it applied equally to whole body ... so body do not experience any gravitational force and there is nothing present in the atmosphere to oppose the fall which results it have maximum acceleration during free fall....

In free fall do all objects fall with the same acceleration?
yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.
