how velocity can be negative too??? And how it can increase with time????
Answers
Answer:
the velocity can never be in negative as velocity means distance divided by time and distance is never negative and time too.
Explanation:
the velocity decreases with time because of the friction produced it only increases with time when an pressure or a flow is provided in regular interval interval of time
Velocity can be negative
Assuming rightward is positive, the velocity is positive whenever the car is moving to the right, and the velocity is negative whenever the car is moving to the left. The acceleration points in the same direction as the velocity if the car is speeding up, and in the opposite direction if the car is slowing down.
Velocity and Time
The object's velocity increases as it accelerates at the beginning of the journey. It remains the same in the middle of the journey (where there is no acceleration). It decreases as the object decelerates at the end of the journey.
