1. What will be the Acceleration of a Car if it Slows from 90 kmh��ℎ to a Stop in 10 sec?  Here, u = 90 kmh��ℎ = 90×518=25ms290×518=25��2 because initially it was moving at a speed of 90 kmph then reached zero. Final Velocity ‘v’ = 0 kmph, and t  = 10 seconds Now, applying…

If r→�→represents displacement vector and v→=dr→dt�→=d�→d� represents the velocity, then; Acceleration:  a→=dv−→dt=d2v−→−d2t�→=d�→d�=d2�→d2� In one dimensional motion, where x is the displacement, and v=drdt�=d�d� is the Velocity, then; a=dvdt=d2xd2t�=d�d�=d2�d2� Example 1: A car starts from rest and achieves a speed of 54 kmh��ℎ in 3 seconds. Find its Acceleration? Solution:  v0�0 = 0, vt�� = 54…

In Physics , Acceleration is described as the rate of change of Velocity of an object, irrespective of whether it speeds up or slows down. If it speeds up, Acceleration is taken as positive and if it slows down, the Acceleration is negative. It is caused by the net unbalanced force acting on the object,…

We already know that Velocity is a speed with direction; therefore, it is a vector quantity. The Acceleration ‘a’ is given as: a=Change in VelocityTime Taken�=Change in VelocityTime Taken This formula states that the rate of change in Velocity is the Acceleration, or if the Velocity of an object changes from its initial value ‘u’…

When a stationary car starts suddenly, we get pushed up backward, and when brakes are applied, we get pushed forward against our seat, or when our car takes a sharp right turn, we get pushed towards the left. We experience these situations because our car is accelerating. Simply when there is a change in Velocity,…
