breaking distance and kinetic energy. Flashcards
1
Q
what equation would you use when calculating the change in kinetic energy?
A
ΔEk= 1/2 mv² - 1/2 mv²
2
Q
why do the wheels on an F1 car get hot when it breaks?
A
when a car brakes kinetic energy stored by the car is transferred into the thermal energy store of the brakes due to friction when it breaks. this is the dissipated to the thermal energy store of the surroundings via heating.
