Newton’s second law Section 3.1
Warm up • What is acceleration? • How do we calculate acceleration?
Acceleration An unbalanced force causes an object to accelerate.
What type of force is represented in each of the following figures?
The acceleration of an object is directly proportional to the net force acting on the object…..…… the acceleration of an object is inversely proportional to the mass of the object.
Newton’s second law of motion Acceleration = Fnet mass
Relation between acceleration and forces • Large Force = Large Acceleration F a
Application …. 1- If the mass of a helicopter is 4500 Kg, and the net force on it is 18000N, what is the helicopter’s acceleration?
Application 2- what is the net force with a mass of 900 Kg if its acceleration is 32.0 m/s2?
Application 3- a car is being pulled by a tow truck. What is the car’s mass if the net force on the car is 3000N and it has an acceleration of 2.0m/s2?
