What Is The Relationship Between Mass And Kinetic Energy. Mathematically expressed as-KEfrac12mv2 Where m is the mass of the object measured in kg. This proportionality implies that if the mass is doubled its kinetic energy is doubled too.
Momentum is also conserved in collisions while kinetic energy. There is direct proportionlaity relation between KE and mass. It is defined as the energy required by a body to accelerate from rest to stated velocity It is a vector quantity.
The SI Unit of Kinetic Energy is Joules.
If you drop the sack the mass will accelerate due to gravity and all the potential energy will be converted to kinetic energy of motion of the mass the instant before it strikes the ground. For example if the mass is 2kg and velocity 2ms so kinetic energy as per the formula 12 m v2 is 12222 4J and if you increase the mass by 2kg the KE12 4 228 J. The velocity of a 300 kg particle is given by 800tš 300š”2š ms with time t in seconds. If you drop the sack the mass will accelerate due to gravity and all the potential energy will be converted to kinetic energy of motion of the mass the instant before it strikes the ground.
