Meenu observed that as a stone of mass 1kg falls freely from a height 1m, its potential energy gets converted into kinetic energy. Therefore, its potential energy decreases and kinetic energy increases. As the stone touches the ground, all its potential energy is converted to the kinetic energy.
Renu observed that as a stone of mass 1kg falls freely from a height 1m, its potential energy gets converted into kinetic energy. Therefore, its potential energy decreases and kinetic energy increases. As the stone touches the ground, all its potential energy is converted to the kinetic energy.
Differentiate between kinetic energy and potential energy with relevant formulas and examples.
Define kinetic energy and provide its formula.
A cyclist travels along a straight path with a constant acceleration of 2 m/s². If the cyclist's initial velocity is 5 m/s, what is the cyclist's velocity after 4 seconds? Also, calculate the total distance covered in this time.
A ball is dropped from a height of 10 m. If the energy of the ball reduces by 40% after striking the ground, how much high can the ball bounce back?
