    1))) According to Newton’s laws, an object will remain stationary or move at constant velocity unless acted by a force. If a force (F) is applied, the object will accelerate according to F=m·a, where “m” is the mass of the object and “a” is its acceleration. The unit of force is the Newton (N), N is kg·m/sec a) Consider a stationary object with a mass of 5 Kg, acted on by a force of 10 N. What is its acceleration?...
