This is Newton's First Law of motion.
What is "An object in motion stays in motion and an object at rest stays at rest unless acted upon by an external force"?
This is the resulting Net Force from a 4N Northwestern Force and a 4N Southeastern force.
What is 0 N?
These are the two most often used trig functions to relate angled components to horizontal and vertical components of a force vector.
What are sine and cosine?
Net force is equal to this, as shown by Newton's Second Law.
What is mass times acceleration?
This is the direction that a force would have to act on this box to make the box's acceleration 0.
What is to the left?
This is the value of the x-component of a 10 N force vector acting 45 degrees above the horizontal.
What is 7.07 N?
This is the net force acting on an object with constant velocity.
What is no net force?
This is the free body diagram of a box being pulled up an incline, where the string pulling the box is parallel to the incline surface.
What is see slides?
What is 31 degrees?
These are the individual accelerations of a 1kg and 10kg box each experiencing 5N of force.
What is 5 m/s^2 and 0.5 m/s^2?
This is the acceleration a 4kg block would experience under a tension force of 80N at 10 degrees with a coefficient of static friction of 2.
What is 19.7 m/s^2?
This is the angle where the magnitude of Tx is double the magnitude of Ty.
What is 27 degrees?
This is the acceleration of a 2.5 kg box experiencing 6 7 N of force.
What is 26.8 m/s^2?
This is what the coefficient of static friction has to be to stop a 5kg block being pulled at 4N at 30 degrees from moving.
What is 0.08?
This is the angle where a 5kg block being pulled with 30N (and no friction) moves with an acceleration of 2.34 m/s^2.
What is 67 degrees?
