Chapter 3 Kinematics Quiz

Displacement is the change in position from the initial position to the final position. It is calculated by subtracting the initial position from the final position.

The equation for average velocity is v = (r - ro) / (t - to), where v is the average velocity, r is the final position, ro is the initial position, t is the final time, and to is the initial time.

The instantaneous velocity represents the speed and direction of motion of an object at a specific moment in time.

The equation for average acceleration is a = (v - vo) / (t - to), where a is the average acceleration, v is the final velocity, vo is the initial velocity, t is the final time, and to is the initial time.

The equations of kinematics in two dimensions are: v = vo + at, x = (vo + v) t / 2, v = vo + 2ax, x = vot + at^2, v_x = vox + ax t, x = (vox + vx) t / 2, v = v + 2a x, x = (vox + vx) t / 2.
