A CAR IS MOVING AT UNIFORM SPEED OF 50 KM / HR ON A STRAIGHT ROAD . WHICH FORCES ARE ACTING ON THE CAR ? ARE THIS FORCES BALANCING EACH OTHER ? IF ONE OF THE FORCE INCREASES WHAT COULD BE THE POSSIBLE RESULTS ?
The forces acting on car are:
Weight of car (Downward)
Normal reaction (Upward)
Friction force
Driving force
Weight of car and normal reaction balance each other as they are equal.
Car that is moving with constant velocity is said to be in equilibrium or we can say that all the forces are balancing each other only if it follows following conditions:
(i) The net force acting on car is zero.i.e., ∑ → F = 0
(ii) If the car is in equilibrium, then the acceleration can be zero. i.e., → a = 0
Here the car is in uniform motion as the vector sum of all the forces acting on an object is zero(driving force = opposing friction force).
If one of the force increases, then the state of uniform motion will be changed.
