Yes I can! I shall now do so, ignoring the effects of air resistance:
During free fall, the direction of motion doesn't change. But the speed increases, steadily
and continuously.
The amount by which the speed increases each second is called the "acceleration of gravity".
On earth, the speed is 9.8 meters per second (32.2 ft per second) greater after each second
of free fall.
What else can I help you with?
Can you describe how velocity changes during free-fall?

If an object free-falls for 2.6 seconds what will be its final velocity and how far will it fall?
The final velocity of an object in free-fall after 2.6 seconds is approximately 25.48 m/s. The distance the object will fall during this time is approximately 33 meters.
Explain why parachutist and snowflakes donot fall with a constantly accelerating motion?
Parachutists and snowflakes do not fall with constantly accelerating motion because of air resistance. As they fall through the air, they experience a drag force that counteracts the force of gravity, eventually reaching a terminal velocity where the forces are balanced and they fall at a constant speed. This prevents them from accelerating indefinitely.
An object is in free fall until it reaches terminal velocity?
During free fall, an object accelerates due to gravity until air resistance balances the gravitational force, reaching terminal velocity. At terminal velocity, the object falls at a constant speed because the air resistance is equal to the force of gravity acting on it.
You drop a ball from a cliff it lands 4 seconds later what is the balls average speed during the 1st second it is in free fall?
The basic equation for average velocity is distance over time. However, if the velocity is changing uniformly, as it is in free fall, you can use initial velocity plus final velocity divided by two. That makes this problem easy. In free fall the object accelerates at 9.8 m/ss. That means every second it picks up 9.8 m/s of speed. So if is dropped from rest, then one second later its speed will be 9.8 m/s. Its average speed during that time is then initial velocity = 0 plus final velocity = 9.8 divided by 2, to get ; 4.9 m/s.

What is the rate at velocity changes?
Acceleration is the rate at which velocity changes. When velocity is decreasing, sometimes the word "deceleration" is used instead. Acceleration and deceleration describe generally how velocity can change. Keep in mind that things can get a little more complicated than just speeding up or slowing down. For example, in an elevator going up, you can feel increased G force resulting from acceleration upward, and you can also feel increased G force if the elevator is in free-fall and it decelerates.Acceleration is mathematically described as:a = dv/dtwhere dv is the change in velocity over a specific period dt.The rate at which velocity changes is either acceleration or deceleration, and it is expressed by: a = Δv/t acceleration = change in velocity / time takena = F/m acceleration = resultant force / massHowever, since velocity is a vector quantity (it has both value and direction), acceleration also is a rate at which direction changes when velocity is constantThe rate of change in velocity is known as acceleration.

How did the elevator changed?
The two big changes to elevators were the fall protection device, or velocity limiter, and variable power DC motors.
What is the greatest velocity an object reaches during free fall?
Assuming this is a free fall on the earth, the highest velocity an object in free fall can reach is 9.8 meters per second or 32 feet per second.answer 2. above is described the acceleration due to gravity on Earth.The Q asks for the Highest velocity. This is known as the Terminal Velocity.This depends upon buoyancy, air-resistance and so on. The terminal velocity of a Parachutist is much less than that of a rock. But Terminal Velocity is their greatest velocity.
What is the final velocity?
Perhaps you mean Terminal Velocity, as in a parachute fall? This is the maximum speed reached in the fall. Final velocity will be zero, assuming you arrive on the ground.
Is there a sonic boom during fall?
Usually not. Most objects have a terminal velocity that is considerably less than the speed of sound.

What are the emotional and social changes between male and female during puberty?
they fall in love.
