What is the gain in speed per second for a freely falling object?
Solution 19RQ Introduction For a freely falling object, the acceleration will be same since there is no external force is applied on it. The only force is gravitational force which is acting on the body. The acceleration due to gravity is a constant and it is represented as “g”. Step 1 According to the equation of motion. The equation for the velocity in free fall would be, v = u + at Where, u - initial velocity a - acceleration t - time taken At initial condition, t = 0 and u = 0 t = 0 then v 10. If t = 1 second, v =2 + gt a = g since the acceleration is acceleration due to gravity. v2= 0 + g × 1 seconds = g m/s Therefore, the change in velocity would be, v - v = g m/s - 0 m/s = g m/s 2 1 v3= 0 + 2 g = 2g m/s So, v3 v2 2g - g = g m/s So, the gain in speed in each second would be g m/s.
