hich of the following is true of a free-falling body?a. It moves with non-uniform motionb. It has zero velocityc. It has constant non-zero accelerationd. It has non-uniform acceleration

If ______ is the only force acting on an object, the object is said to be in free fall.Multiple choice question.accelerationdecelerationgravityfriction

Which of the following situations is true and possible?a. If the velocity of a body is zero, then the acceleration can be non-zerob. A body moving at a constant velocity can have accelerationc. The magnitude of distance and displacement are equal in a circular motiond. All of the above

The acceleration of a body cannot be zero at a point where Question 3Answera.None of these b.The average velocity is positivec.The average velocity is negatived.The instantaneous velocity is positive but decreasinge.The instantaneous velocity is zero

A moving body is covering distances which are proportional to square of the time. Then  the acceleration of the body is               (a) constant but not zero (b) increasing         (c) zero  (d) decreasing

Let we bar and bar denote the velocity and acceleration of a body respectively then option A can be non zero when we bar is zero option B A must be zero when we bar is zero option c a bar maybe 0 when we were is not equals to zero a bar must be zero where we bar is constant
