What is the net force on a car if the force of friction is 15 N and the forward force due to the engine is 20 N?
ICE Princess25 [194]
5 newton forward because the force of the engine is greater than the force of friction so that means the car is going forward.
You can think of this: when friction is greater than the force of an object its slowing down but when the force of the car is greater than the force of friction its speeding up.
Hope this helps
