1 Newtons Second Law unit 6.4 year 10

2 Newtons Second Law Newton's second law of motion pertains to the behaviour of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables -the net force acting upon the object and -the mass of the object.

3 Newtons Second Law Unbalanced forces There is an acceleration Acceleration depends directly on the NET FORCE Acceleration depends inversely on the objects mass

4 Newtons Second Law Definition: An object will accelerate if an unbalanced force is applied to it. Its acceleration will depend on the size of the force and the mass of the object.

5 Newtons Second Law Definition: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

6 Newtons Second Law Equation: a = F net / m or F net = ma unit equivalency 1 Newton = 1 kg x 1 m/s/s

17 the BIG misconception The most common misconception is one that dates back for ages; it is the idea that sustaining motion requires a continued force.

18 the BIG misconception Newton's laws declare loudly that a net force (an unbalanced force) causes an acceleration; the acceleration is in the same direction as the net force. To test your own belief system, consider the following question and its answer.
