The simplest answer is that gravity is the field created by a mass distribution in the spacetime around it; gravitational force is the force exterted by the field on a test mass in the field.
<em>Acceleration at 50m/sec² : means every second the velocity increases by 50 m/sec. In 3 seconds the velocity increases by 150 m/s. So total will be 160 m/sec.
the formula is</em>
<em> V = final velocity = U initial velocity + acceleration a * time duration t</em>
<em> V = 10 m/s + 50 m/sec² * 3 sec = 160 m/sec</em>
