KINETIC ENERGY NSS TRAINING COLLEGE OTTAPALAM- ICT WORKSHOP DIGITAL TEXT Name of the teacher :PRAVEENA K    Date  :  20/5/22                                  Department : Physical Science        Class       : 9th                    Subject    : Physics  Duration  : 40 minutes Unit         : Work, Energy and Power  Topic      : Kinetic Energy Objectives:  The study of kinetic energy helps  To understand the energy possessed by objects due to its motion and define it. To give examples of objects having kinetic energy. To analyse situations and distinguish if objects possess kinetic energy or not. To understand the two factors affecting kinetic energy. To give the equation of kinetic energy for solving numerical problems.  Energy is defined as the capacity to do work.  Work is done to displace the box from position1 to position2 shown in the figure.  Work,   W= Force * Displacement If F is the force and d is the displacement, W=F*d Unit of work is Joule or Newton second.  There are differ

Laws of motion

 Sir Issac Newton formulated the three laws of motion in physics.  Newton's first law - Every body continues in its state of rest or of uniform motion unless an unbalanced external force acts on it.  Newton's second law - The rate of change of momentum of a body is directly proportional to unbalanced external force acting on it.  F=ma, m is the mass and a is the acceleration  Newton's third law- For every action  there is an equal and opposite reaction.  For detailed description  click here
