why does a car stop when brakes are applied force bro please give my answer correct it is 2 marks question I will give you like and mark you brilliant
Answers
Answer:
When we apply brakes to a vehicle, it stops because of the retarding force. This occurs in a way such that the total loss in momentum of the vehicle is equal to the gain in momentum of the brake system i.e. change in momentum of the applied force. So, the total momentum of the system remains conserved.
Correct Question:
why does a car stop when brakes are applied force?
Answer:
According to the Newton's first law of motion:-
"every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force"
So, the car in motion , remains to be be in motion unless breaks are applied and its stopped.
- This retardation happens when the breaks stops the wheel. When we apply break, a force called friction works. This works in opposite direction, that is , in the opposite direction of motion of the car, And this brings the car to rest.
Extra Information:-
- What is momentum ?
The linear momentum of a body is defined as product of mass and velocity.
- Odometer is a device used to measure the distance traveled by vehicle.
- Distance is directly proportional to time².
- If a body travels unequal distance in equal interval of time then it is aid to be non uniform motion.
- If a body travels equal distance in equal interval of time then it is aid to be in uniform motion.
- Instataneous speed is the speed in particular instance of time.
