Flashcards do conjunto (53)

  1. 1Frame of ReferenceA framework that is used for the observation and mathematical description of physical phenomena and the formulation of physical laws.
  2. 21. Dynamics 2. Kinematics1. explains the causes of motion
    2. Describes motion
  3. 3DistanceHow far an object moves/total ground it covers (scalar quantity)
  4. 4Scalar QuantityDefined by magnitude or volume
  5. 5Displacement(x) Distance and direction with respect to the origin
  6. 6Vector QuantityRequires magnitude and direction
  7. 7Average SpeedDistance per time
  8. 8Equation for speedS=(d/t)
  9. 9Average Velocity (v)Displacement per time
  10. 10Change in Displacement Formula∆x=(xf)-(x0)
  11. 11Equation for VelocityV=((∆x)/t)
  12. 12Constant Displacement∆x=0, v=0
  13. 13Constant VelocityLinear relationship where x changes with respect to time. Positive velocity moves forward, up, or right. Negative velocity moves backward, down, or left.
  14. 14Displacement Formula∆x=v*t
  15. 15Acceleration (a)A change in velocity over a time interval.
  16. 16When is an object speeding up?When velocity and acceleration have the same sign.
  17. 17When is an object slowing down?When velocity and acceleration have opposite signs.
  18. 18Equation for Accelerationa=((∆v)/t)
  19. 19Equation for Change in Velocity∆v=(vf)-(v0)
  20. 20Constant AccelerationThe velocity changes regularly with respect to time. Since the velocity is changing, the slope must change, causing for a curved line (parabolic relationship).
  21. 21What does the slope of a velocity graph tell you?The acceleration of that object.
    *remember that you can solve by using the units to figure out the relationship
    (velocity vs time graph: v=m/s t=s thus, acceleration is v/t = m/s^2)
  22. 22What does the area under the curve of a velocity graph tell you?The displacement of an object.
  23. 23A graph that is concave up has (...) accelerationPositiveA graph that is concave up has (...) acceleration
  24. 24A graph that is concave down has (...) accelerationNegativeA graph that is concave down has (...) acceleration
  25. 25What equation uses... V0 ∆x 1/2 Vf t∆x=.5((v0)+(vf))t
  26. 26What equation uses... V0 t a t^2 ∆x .5∆x=((v0)t) + .5at^2
  27. 27What equation uses... a Vf t V0Vf=(v0) + at
  28. 28What equation uses... V0^2 2 Vf^2 ∆x aVf^2=(v0^2)+2a∆x
  29. 29Free FallObject acts under the influence of gravity alone. Assumes air resistance is negligible. Gravity is a constant force.
  30. 30What is the acceleration due to gravity?g=-9.8 m/s^2
  31. 31For free fall, what can you do to the equations to constant acceleration?Substitute -9.8 in for a. Substitute ∆y in for ∆x (height).
  32. 32What is always important to remember of the x and y planes?They are independent of each other.
  33. 33Horizontal Component (x)Constant Velocity
  34. 34Vertical Component (y)Constant acceleration due to the force of gravity
  35. 35Why is the path of a projectile always a parabola?∆x remains constant (constant velocity) while ∆y changes exponentially (due to acceleration)
  36. 36Constant Velocity Trigonometric EquationVx=(V0)*cos(Θ)
  37. 37Initial Velocity Trigonometric EquationV0y=(V0)*sin(Θ)
  38. 38X-MotionConstant velocity. Definition of Velocity Equation: ∆x=(Vx)t
  39. 39Y-MotionConstant acceleration due to gravity. Free fall equations.
  40. 40What is the only similar thing between the x and y planes?time
  41. 41Range (∆x)Horizontal displacement. It is dependent on the launch velocity and angle (Vx)
  42. 42What angle allows for maximum range?45º
  43. 43Complimentary AnglesSum of two angles is 90º.
  44. 44Velocitydisplacement over time
    dis/time
  45. 45AccelerationChange in velocity / Time
    a = Δv/Δt
    simple ex.: a= Vf-Vi/t
  46. 46Horizontal VariablesHorizontal Variables
  47. 47Horizontal Kinematic EquationsHorizontal Kinematic Equations
  48. 48Vertical VariablesVertical Variables
  49. 49Vertical Kinematic EquationsVertical Kinematic Equations

  52. 52TrajectoryThe path an object follows
