Relation between kinetic energy and maximum height of a projectile |

Answer» K.E of a projectile at its maximum height?Still have a question? ASK your own!What is your question?15 ANSWERSShivang Verma, StudentAnswered Aug 3 2017It depends UPON whether the projectile is vertically UPWARDS or at an angle with HORIZONTAL.1: If body is moving vertically upward then it would definitely be zero at the top most point since there is only vertical velocity applied to the body (in Y direction). Thus at the top most point the kinetic energy becomes zero as “Ke=1/2mv²” and v(velocity) is zero here. Instead entire kinetic energy changes to potential energy.2. If a projectile is PROJECTED at some angle to the horizontal then the velocity wouldn't be zero at the top most point. Since Ke=1/2*mv² and here the velocity is the resultant of two velocities at horizontal direction and vertical direction which is given by the parallelogram law of vector. |
