Newton’s 1 st Law: More Practice

Newton’s 2 nd Law of Motion: Student Learning Goal The student will be able to state Newton’s 2 nd Law and apply it in qualitative and quantitative terms to explain the effect of forces acting on objects. (B3.4)

Newton’s 2 nd Law of Motion and Weight

Newton’s Second Law of Motion If the net force on an object is not zero, the object will be accelerated in the direction of the net force.

Newton’s Second Law of Motion If the net force on an object is not zero, the object will be accelerated in the direction of the net force.

Newton’s Second Law of Motion If the net force is not zero, the object will be accelerated in the direction of the net force. i.e. the more massive the object, the harder it is to change its motion (the higher its inertia).

Newton’s Second Law of Motion If the net force on an object is not zero, the object will be accelerated in the direction of the net force.

Weight The formula F = ma can also be used to calculate the weight F g of an object

Weight The formula F = ma can also be used to calculate the weight F g of an object, the magnitude of the force of gravity acting on it

Weight The formula F = ma can also be used to calculate the weight F g of an object, the magnitude of the force of gravity acting on it, if the acceleration a is...

Weight The formula F = ma can also be used to calculate the weight F g of an object, the magnitude of the force of gravity acting on it, if the acceleration a is the acceleration due to gravity, g = 9.8 m/s 2.

Weight (mass is measured in kg)

Weight Weight is therefore measured in Newtons. And the direction of the force is always [down].
