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.
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.
Define power. How will you differentiate between kW and kW h? If the velocity of a ball is tripled, what will be the ratio of
Four men lift a 250 kg box to a height of 1 m and hold it without raising or lowering it.
