if an object of 2 kg mass at some height have 100 joule potential energy. if it released from height what will be the speed at when it strike the ground?
Answers
Answer:
When an object is dropped from a height, its gravitational potential energy is converted to kinetic energy as it falls. The loss in potential energy will be equal to the gain in kinetic energy. We can simply calculate the gravitational potential energy lost using the formula E, = m. g: h: + Ex = ((20) - (9. 81) - (10)) J = 1962 J Therefore, the maximum kinetic energy held by the object is 1962 J.
Answer:
We know that energy cannot be created nor destroyed - therefore it will still be 200J when it hits the ground
When GPE Increases = KE Decreases
When GPE Decreases = KE Increase
Draw a diagram of a ball falling and above that ball write GPE = 200J & KE = 0J (assuming its not in free fall at this point and we are holding it per say)
And beside that draw the same diagram but this time the ball touching the ground, GPE = 0J & KE = 200J
