Webno, we assume that friction is given by the equation (coefficient of friction)*normal force. That doesn't vary. also the formula works as long as you use average force. Doesn't have to be constant ( 6 votes) Hafsa Kaja Moinudeen 7 years ago How does energy change into heat? Heat is something physical, that which we can feel but energy isn't,right? WebApr 12, 2024 · Work Done in Physics When we give a thrust to a block with some force ‘F’, the body travels with some acceleration or, also, its speed rises or falls liable to the direction of the force. As the speed surges or declines, the kinetic energy of the system alters.

WebFeb 20, 2011 · In this problem, work done by friction will be negative because the force is applied in the opposite direction as the motion, and will decrease the initial energy, giving us a Final Energy result that is less than the initial energy because energy is lost to friction. Since cosine of 180 is negative 1, the work done by the force of friction is negative … however i used both methods: the kinematic way and the energy way. For … WebJun 4, 2013 · The coefficient of friction varies for different combinations of materials.The work done is the force multiplied by the distance.
