kinematics

Question 1

how to use graph to explain a phenomenon change with terms

Answer 1

gradient = ___(a/s/v)
graph quantity increase/decrease at a decreasing/increasing rate in which direction as gradient (changes)

when t = _ , qn quantity changes increase/decrease

Question 2

what are the 4 kinematic equations

Answer 2

1. Displacement-Average Velocity
   $$
   s = \frac{u + v}{2} \cdot t
   $$
2. Final Velocity
   $$
   v = u + at
   $$
3. Displacement with Initial Velocity and Acceleration
   $$
   s = ut + \frac{1}{2}at^2
   $$
4. Final Velocity Squared
   $$
   v^2 = u^2 + 2as
   $$

• $$ s $$: Displacement
• $$ u $$: Initial velocity
• $$ v $$: Final velocity
• $$ a $$: Acceleration
• $$ t $$: Time interval
