Kinematics

Question 1

Kinematic formula missing acceleration (a)

Answer 1

x = x_i + vt

Question 2

Kinematic formula missing distance (x)

Answer 2

v_f = v_i + at

Question 3

Kinematic formula missing time (t)

Answer 3

v_f² = v_i² + Δx

Question 4

Kinematic formula missing final velocity (v_f)

Answer 4

x = v_it + ½at²

Question 5

What are the two kinematic Trigonometry equations and what is the equation of the sum of those two equations?

Answer 5

v_x = vcosθ , v_y = vsinθ ; sum v =√v_x² + v_y²

Question 6

Equation for Force (F) and what are the units?

Answer 6

F=ma (N) (kg·m/s²)

Question 7

What is the equation for Force (F) far from earth’s surface?

Answer 7

F = Gm₁m₂/r²

F σ 1/r²

α (proportional)

Question 8

What are the forces on the block sliding down an incline plane?

What are the equations for both x and y for acceleration and force?

Answer 8

a_x = sinθ and a_y = cosθ (exception for incline planes)

sum F = ma_x = mgsinθ-F_f

Question 9

What is the equation for centripetal motion?

acceleration and force equations

Answer 9

a_c = mv²/ r

F_c = mv²/ r
