-Overuse of a muscle dehydration
– muscle strain or simply
– holding a position for a prolonged period can cause a muscle cramp
– Inadequate blood supply.
perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision.
An inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.
(2ai) In a perfectly elastic collision, no energy is dissipated as heat energy internal to the bodies, and none is spent on permanently deforming the bodies or radiated away in some other fashion.
(2aii) In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies together.
Work is referred to as the process of energy that is transferred to an object’s motion by applying force.
OR WORK is generally represented as the product of displacement and force.
Energy can be defined by which the process of power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
Power is the amount of energy that is transferred in a unit of time.
