Physics Concept Checks Flashcards
When calculating the sum of vectors A and B (A + B), we put the tail of B at the tip of A. What would be the effect of reversing this order (B + A)?
There would be no difference since vector addition is a commutative property
When calculating the difference of vectors A and B ( A - B), we invert B and put the tail of this new vector ar the tip of A. What would be the effect of reversing this order (B - A)?
Vector substration, like vector multiplication, is not a commutative function. The resultant will have the same magnitude but oriented in the opposited direction
What is the formula for average velocity?
What is the universal gravitation equation?
What is the mathematical relationship for static friction?
What is the mathematical relationship for kinetic friction?
What is the center of mass equation?
What is the equation for average acceleration?
What is the mathematical relationship for Newton’s first law?
F(net) = ma = 0
What is Newton’s first law?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
What is the mathematical relationship for Newtwon’s second law?
F(net) = ma
What does Newton’s second law state?
the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object
What is the mathematical relationship of Newton’s third law?
F(a on b) = -F (b on a)
What is Newton’s third law?
For every action, there is an equal and opposite reaction
What is the kinematic equation when displacement is not known?
What is the kinematic equation when final velocity is not known?
What is the kinematic equation when time is unknown?
What is the equation for centripetal force?
What is the equation for torque?
