Definition: Maximum height (hmax) in vertical projection is reached when the vertical velocity component becomes zero.

Highlight: The time of ascent equals the time of descent in vertical projection, making the motion symmetrical.

Example: Rolling wheel motion combines two components: rotational motion around its axis and translational motion of its center.

Vocabulary: Rolling without slipping occurs when the point of contact has zero velocity relative to the ground.

Definition: Angular velocity (ω) represents the rate of angular displacement and is measured in radians per second.

Vocabulary: Period (T) is the time taken for one complete revolution.

Highlight: The relationship v = ωr connects linear velocity $v$ to angular velocity (ω) and radius $r$.

Example: Centripetal acceleration (a₍) is always directed toward the center of the circle and equals v²/r.

Definition: Horizontal projection combines uniform horizontal motion with accelerated vertical motion.

Example: The trajectory forms a parabola due to constant horizontal velocity and accelerating vertical motion.

Highlight: Final velocity can be calculated using v = √$v₀² + 2gh$, combining both motion components.

Vocabulary: The range (R) of horizontal projection depends on initial velocity and height, calculated as R = v₀√$2h/g$.

Definition: Average velocity (Vśr) represents the overall rate of position change over a given time interval.

Vocabulary: Relative velocity (v₁) describes motion with respect to a reference frame.

Example: In free fall motion, the displacement equation h = $1/2$gt² shows how height changes with time under gravitational acceleration.

Highlight: The relationship between final velocity and height in free fall is given by v = √(2gh), a crucial equation for practical calculations.
