Description : What is the acceleration of a moving object ? Explain. ?
Last Answer : An object moving at the same speed there is no change in the initial velocity ( u) and the end velocity ( v) at any given time. We know that the rate at which an object changes over time is called acceleration. Acceleration , a = v-ut = u-ut = 0t = o So there is no acceleration of a moving object.

Description : can average speed of a moving object be zero -Physics 9th
Last Answer : Answer : No Explaination Speed is the distance travelled in the given time. Distance can never be zero. Therefore, average speed will always be a positive value and will not be zero. Speed is a scalar quantity and has only magnitude.
Description : Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between 4th and 5th seconds -Physics 9th
Last Answer : Uniform acceleration in the interval between 4th and 5th seconds = = (5u + 1/2 * a * 5^2) - (4u + 1/2 * a * 4^2) = 5u + 1/2 *a * 25 - 4u + 1/2 * a * 16 = u + 1/2 * a * (25-16) = u + 1/2 * a * 9 = u + 9/2 * a If it starts from rest then the displacement will be 9/2a. hope this helps!
Description : The distance moved and the magnitude of displacement are equal in ? (a) The earth is revolving around the Sun (b) Object moving in circular path (c) The pendulum is moving to and fro (d) Object moving on straight road -Science

Description : What is the velocity of an object moving in equilibrium and velocity ?
Last Answer : In case of velocity, the velocity of the object does not change with time. Because , the object moves at the same speed. Again , as the object moves at a balanced acceleration, its velocity changes in a linear way over time.
Description : What is the nature of velocity versus time in the case of an object moving at a steady acceleration from a stationary position ?
Last Answer : In the case of an object moving at a steady acceleration from a stationary position, the velocity versus the time line will be a straight line to the point.
Description : Why is there no acceleration of an object moving at equal speed ? Explain ?
Last Answer : The rate of change of velocity is zero because the value of velocity of a moving object does not change. Due to this the acceleration is also zero. That is `a = (vu) / t = (vv) / t`
