●● What is kinematics?
Answer: The study of motion without considering the forces causing it.


●● What is kinetics?
Answer: The study of motion using the forces and moments causing it.


●● How is position defined in rectilinear kinematics?
Answer: By its coordinates with respect to the origin O.


●● What is displacement?
Answer: The change in position of a particle.


●● How is velocity defined?
Answer: v = lim(∆t→0) ∆s/∆t = ds/dt.


●● How is acceleration defined?

, Answer: a = lim(∆t→0) ∆v/∆t = dv/dt.


●● What is the kinematic equation for velocity with constant
acceleration?
Answer: v = v0 + at.


●● What is the equation for displacement under constant acceleration?
Answer: s = s0 + v0t + 1/2 at².


●● What relation does v² = v0² + 2a(s − s0) describe?
Answer: It relates velocity to displacement without explicit dependence
on time.


●● What is required for changing rectilinear motion?
Answer: A series of functions or graphs to specify motion at different
time intervals.


●● What does the slope of the s(t) graph represent?
Answer: The velocity, v = ds/dt.


●● What does the slope of the v(t) graph represent?
Answer: The acceleration, a = dv/dt.
