  1. Resultants vs Equilibrants Resultant - Equilibrant- Two forces of 70N and 30N act concurrently at 0 degrees to each other… Resultant = Equilibrant = Two forces of 70N and 30N act concurrently at 180 degrees to each other… Resultant = Equilibrant =

  2. Maximizing and Minimizing the Resultant Two forces of 70N and 30N act concurrently at 0 degrees to each other… Two forces of 70N and 30N act concurrently at 180 degrees to each other… “As the angle between two force vectors of 70N and 30N goes from 0˚ to 180˚, the resultant goes from _______________ to ________________”

  3. N2L: Newton’s Second Law- Frictionless.. A 20kg box is pushed on a frictionless surface with a force of 50N. a) What is the weight of the box? b) What is the acceleration of the box? Friction.. A 20kg box is pushed on a frictionless surface with a force of 50N. The force of friction is 25N. a) What is the net force on the box? b) What is the acceleration of the box?

  4. Mathematical Relationships using N2L F = ma #1: Effects of Force on Acceleration (Constant Mass) What force is necessary to accelerate What would acceleration be if we a 50kg object on frictionless surface at doubled and tripled the force? 1m/s2? Big Idea - Force (N) Acceleration (m/s2)

  5. Mathematical Relationships using N2L F = ma #2: Effects of Force on Mass (Constant Acceleration) What is the acceleration of a What force ‘F’ is necessary to keep the 200N force on a 100kg object? same acceleration on mass of ‘2m’ and ‘4m’ ? Big Idea - Force (N) Mass (kg)

  6. Mathematical Relationships using N2L F = ma #3: Effects of Mass on Acceleration (Constant Force) What is the mass of an object if a If the force remained the same, what 25N force accelerates it at 1m/s2? acceleration would a 50kg and 100kg object have? Big Idea - Acceleration (m/s2) Mass (kg)

  7. Mathematical Relationships using N2L F = ma Check Understanding… If force ‘F’ is exerted on mass ‘m’ Force ‘F’ is exerted on mass ‘m’ giving accelerating it at ‘a’, what force acceleration ‘a’. What would acceleration would be needed to give be if force ‘F’ was exerted on mass ‘3m’ ? acceleration ‘4a’ ? An object is accelerating at 10m/s2 when Force ‘F’ is exerted on mass ’m1’ giving it the net force on it is cut in half. What is acceleration ‘a’. If force ‘4F’ gives ‘m2’ the acceleration now? an acceleration of ‘2a’, what is the ratio of m1 to m2?

  8. Expanding N2L F = ma a = Δv t • A net force of 50N is applied to a 10kg A retarding force of 75N is exerted on a • block initially at rest on a frictionless 50kg object initially traveling at +10m/s… • surface… • a) How long until the object comes to rest? • FBD • b) How far did the object go during that time? • What will be the final velocity if the • force is applied for 5 seconds? • c) sketch the v-t graph v t
