Question

study the following activity and answer the question take to aluminium channels of different lengths place the lower end of the channels on the floor and hold their offer ends at the same height now take 2 balls of the same size and weight and release them from the top end of the channels they will roll down and cover the same distance questions 1. at the moment of releasing the balls which energy do the balls have second at the ball roll down which energy is converted into which author form of energy Tod why do the balls cover the same distance on rolling down IV what is the form of the eventual total energy of the balls V which law related to energy does the above activity demonstrate explain

Answer 1

1448.

a) when the balls are about to be released, they are in rest. however they have undergone a change in position, so they have Potential energy.

b) when the ball starts moving down the slope, the ball attains a velocity as it goes down. It also undergoes a change in position.

Therefore at this time there is a shift of potential energy into the kinetic energy.

c) the law of conservation of energy governs the above phenomenon.

1448
