Gravitational Potential Energy is the energy of a body that is placed at a certain height and that is subject to a force (its weight).]]> 2018-11-26 18:48:46 UTC https://padlet.com/e_groppi1/yn04kxxer1a0/wish/307958355 4) Kinetic Energy. e_groppi1 https://padlet.com/e_groppi1/yn04kxxer1a0/wish/307958478 What is kinetic energy  (KE) and how to calculate it.

Kinetic Energy is the energy of body that is travelling at a certain speed. It depends on the mass of the body and on the speed.]]> 2018-11-26 18:48:56 UTC https://padlet.com/e_groppi1/yn04kxxer1a0/wish/307958478 6) Mechanical Energy e_groppi1 https://padlet.com/e_groppi1/yn04kxxer1a0/wish/308177474 The Mechanical Energy of a body is the sum of the kinetic energy of the body and of its potential energy.
When there is no friction, the total amount of mechanical energy is constant.

Work done is energy transferred.
Every time there is a change in energy, there is a force exerting on a body that is moving. The force is doing a work equal to the energy being transferred. ]]> 2018-11-30 15:36:19 UTC https://padlet.com/e_groppi1/yn04kxxer1a0/wish/309821014 2b) e_groppi1 https://padlet.com/e_groppi1/yn04kxxer1a0/wish/309877381 10 minutes
