The discussion focuses on calculating the loss of kinetic energy during braking and the power dissipated as heat in the brakes. The primary formula used is KE = 1/2 mv² for kinetic energy, while the work done is calculated using the formula Work = Force x Distance. In cases of non-constant braking force, integration of the dot product of the force vector and the differential x-vector is necessary. To determine power generation, one must calculate the energy dissipated per unit of time.
PREREQUISITESPhysics students, automotive engineers, and professionals involved in vehicle dynamics and braking system design will benefit from this discussion.
Yes. The braking force x stopping distance (assuming constant braking force) is equal to the loss of kinetic energy of the vehicle.xto said:What formula should i use to calculate
the loss in kineti energy during braking and
the power dissipated as heating in the brake
do i just use ke=1/2mv^2 and work done =force x distance ?
And if it's not constant, you can integrate the dot product of the force vector and the differential x-vector.Andrew Mason said:Yes. The braking force x stopping distance (assuming constant braking force) is equal to the loss of kinetic energy of the vehicle.
