I,think potential energy is mgh so 65*100*9,81
Designing warning and evacuation systems could be a step in a plan designed to mitigate the negative impacts of a natural hazard.
The first one is revolves
Balancing.
When the same force is applied from both sides,the forces cancel out each other.
Newtons second law of motion: "T<span>he acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object."
kinetic energy is energy that an object posses while in motion and to get that it must have potential energy.</span>
