Assertion: The trajectory of an object moving under the same accleration due to gravity can be straight line or a parabola depending on the initial conditions.
Reason: The shape of the trajectory of the motion of an object is determined by the acceleration alone.

Assertion :- The shape of trajactory depends on the acceleration and intial condition of motion. Reason :- Trajectory of an object moving under a constant acceleration may be a straight line.

Show that area under the velocity-time graph of an object moving with constant acceleration in a straight line in certain time interval is equal to the distance covered by the object in the interval.

Show that the area under the velocity-time graph of an object moving with constant acceleration in a straight line in certain time interval is equal to the distance covered by the object in that interval.

Assertion : An object may fall with a constant velocity. Reason : This happens when acceleration of the object is equal to acceleration due to gravity.

A : The relative acceleration of two objects moving under the effect of gravity, only is always zero, irrespective of direction of motion. R : The acceleration of object moving under the effect of gravity have acceleration always in downward direction and is independent from size and mass of object.

A : The relative acceleration of two objects moving under the effect of gravity, only is always zero, irrespective of direction of motion. R : The acceleration of object moving under the effect of gravity have acceleration always in downward direction and is independent from size and mass of object.

Assertion : The displacement-time graph of a body moving with uniform acceleration is a straight line. Reason : The displacement is proportional to time for uniformly accelerated motion.
