... 23. If an object weighs 400 N, what is its mass? Mass = Weight / g = 400 / 10 = 40 kg 24. What happens when a net force acts on an object? Its velocity or state of rest changes. The object accelerates. 25. If no net force acts on an object, what is necessarily zero (a) Velocity (b) Acceleration Acce ...
