What acceleration does a parachutist have when falling before opening the parachute?
A parachutist falling before opening the parachute experiences an acceleration due to gravity of approximately 9.81 m/s^2, which is the acceleration due to free fall. This acceleration causes the parachutist's velocity to increase as they fall towards the ground.
What was the acceleration of the shuttlecock during its fall?
The acceleration of the shuttlecock during its fall would be equal to the acceleration due to gravity, which is approximately 9.8 m/s^2 in the absence of air resistance. This means that the shuttlecock would accelerate at a rate of 9.8 m/s^2 towards the ground.
Does the velocity for each second of free fall increase decrease or stay the same?
The velocity for each second of free fall increases. Due to the acceleration due to gravity, the object in free fall accelerates at a constant rate of 9.81 m/s^2. This means that the object's velocity increases by 9.81 m/s every second.
Why do objects accelerate as they fall to the ground?
Objects accelerate as they fall to the ground due to the force of gravity acting on them. As the object falls, the force of gravity causes it to increase in speed, resulting in acceleration. This acceleration is a result of the unbalanced force acting on the object.
Can maximum speed at free fall decrease?
No, the maximum speed at free fall is determined by the rate of acceleration due to gravity (approximately 9.81 m/s^2 on Earth). This means that as an object falls, its speed will continue to increase until it reaches terminal velocity, when air resistance equals gravitational force and the speed remains constant.
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.

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....
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.
Does the velocity for each second of free fall increase decrease or stay the same?
The velocity for each second of free fall increases. Due to the acceleration due to gravity, the object in free fall accelerates at a constant rate of 9.81 m/s^2. This means that the object's velocity increases by 9.81 m/s every second.
