Newton’s law’s Newton’s first law ■ if the resultant force acting on a stationary object is zero then the object will remain stationary. Newton’s first law ■ if the resultant force acting on a moving object is zero then the object will continue moving in the same direction at the same speed in other words with the same velocity. Newton’s second law F (N) a (m/s ² ) M (kg) ■ The acceleration of an object is proportional to the resultant force acting on the object and inversely proportional to the mass of the object. Newton’s second law 1-The object has a mass of 1kg 2-The object has a mass of 2kg calculate acceleration 20N 20N 1kg 2kg The acceleration is inversely proportional to the mass of the object In the other words: (If the mass is larger than the acceleration will be smaller) Newton’s third law ■ whenever two object interact the forces they exert on each other are equal and opposite.
