If an object is dropped from rest at a height of 128 m, the distance it falls during its final second in the air is still 128 m.

The object distance for a convex lens is 20.0 cm and the image distance is 4.0 cm The height of the object is 10.0 cm What is the height of the image?
2 cm
Why would the final kinetic energy before impact be less the initial potential energy of an object dropped from a kilometer height?
It is easiest to think of initial potential energy as the "distance" the object is able to fall. If it has not fallen the distance yet, then of course kinetic energy would be less.
Why does 3 spherical object with different mass will hit the ground at the same time when dropped simultaneously from the same height?
Gravity.
How fast will an object be traveling when it hits the ground if it is dropped from a height of 45m?
You need the amount of time that it took to fall the 45m.
Which factors must be known to calculate an object's gravitational potential energy?
To calculate an object's gravitational potential energy, the following factors must be known: Mass of the object: The gravitational potential energy of an object depends on its mass. The greater the mass of the object, the greater the gravitational potential energy. Height or distance: The gravitational potential energy of an object also depends on its height or distance from the reference point. The greater the height or distance of the object from the reference point, the greater the gravitational potential energy. Acceleration due to gravity: The gravitational potential energy of an object also depends on the acceleration due to gravity at the location of the object. The acceleration due to gravity is a constant value on the surface of the Earth, approximately equal to 9.8 meters per second squared. The formula for gravitational potential energy is: PE = mgh Where PE is the gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height or distance of the object from the reference point.
What experiments can you do with acceleration?
You can drop an object from a certain height and time it to see how fast it goes. Make sure that you find the distance of the height from where you dropped it so that you can find out the speed by dividing the time by the distance.
How high an object bounces depends on?
the height from which it was dropped
Why does an object dropped from a certain height have more than twice the speed of an object dropped from half the height of the previous object?
Because they undergo an acceleration. Free fall velocity is the function of a square.
An object with a mass of fifteen kilograms is dropped from a building neglecting friction which is the buildings height?
It's not possible to calculate the answer with the information given.An object with a mass of 15 kg can be dropped from a building of any height.
The object distance for a convex lens is 20.0 cm and the image distance is 4.0 cm The height of the object is 10.0 cm What is the height of the image?
2 cm
When an object ids dropped from a height it accelerates when it fall down name the force which accelerates the object?
That is called gravity.
Why would the final kinetic energy before impact be less the initial potential energy of an object dropped from a kilometer height?
It is easiest to think of initial potential energy as the "distance" the object is able to fall. If it has not fallen the distance yet, then of course kinetic energy would be less.
How does the height of the object or distance from the surface affect the impact crater?
Due to height and pressure
How long will it take an object dropped from a height of 500 feet to hit the ground?
4 seconds
How do I calculate the distance between current location and a distant visible object if the only information available is the height of the object and the distance between 2 fingers at your eye?
The ratio of the spacing of the fingers and the distance from your eye will be the same as the ratio of the height of the object to its distance from you, so Hf/Df = Ho/Do and Do = HoDf/Hf
Is it true that the average speed of an object object is measured by dividing time by distance?
Yes. You can also find speed by distance divided by height
An object is dropped and is in free fall The speed of the falling object and the distance it falls are measured every second Which of the following is correct?
The speed stays thesame but the distance stays the same.
