When the object hits the ground, the kinetic energy has to go somewhere, because energy isn't created or destroyed, only transferred. If the collision is elastic, meaning the object can bounce, much of the energy goes into making it bounce up again. In all real collisions, energy is lost...

followed by a dramatic week ‘in the dark’ as the full Moon outshone the potential impactor, ruling out further observations. As the Moon moved aside, the skies dimmed and ESA’s Near-Earth Object Coordination Centre (NEOCC) took another look, only to find the chance of impact...

A freely falling object requires 1.30 s to travel the last 21.0 m before it hits the ground. From what height above the ground did it fall? On the moon an object dropped from 3.3metres takes 2 seconds to reach the ground. What is the acceleration of free fall?. A certain freely fallin...
There's nothing like staring up at the night sky to make you feel small. But when looking out into the cosmos, you might also wonder: What is the most massive known object in the universe? In some ways, the question depends on what is meant by the word "object." Astronomers have spo...
An object is launched horizontally at a velocity of 28.0 m/s from the top of a cliff. If the object hits the ground 170.0 m from the base of the cliff, how high is the cliff? An object is thrown downward with an initial speed of 16 m/s from a height of 63 m above the grou...
If an object is dropped from a tall building and hits the ground 3.0\ \mathrm{s} later, what is the velocity of the object when it hits the ground? (Remember that the velocity is downward). For a freely falling object dropped from rest, what is its acceleration at the...
Determine the final velocity at which the object hits the ground. An object is thrown upward from a building that is 70 m high. The initial velocity of this object is 12 m/s. Find the maximum height reached by thi...
