When a stone is thrown vertically upwards its velocity is continuously decreased Why?
When a stone is thrown vertically upwards its velocity is continuously decreased Why? Kinetic energy(K.E) is given by 1/2 mv^2 where, ‘m’ and ‘v’ are the mass and velocity of the body and Potential energy (P.E) = m×g×h where g and h are acceleration due to gravity and height attained by the body respectively. As […]
