Free Fall and Motion

A set of flashcards summarizing key vocabulary and concepts related to free fall and motion from the lecture notes.

Free Fall

The motion of an object experiencing only the force of gravity, with no air resistance.

Initial Velocity

The speed of an object when it is first released or dropped.

Constant Acceleration

An object in free fall accelerates at a consistent rate due to gravity.

Acceleration due to Gravity (g)

The rate of acceleration experienced by an object in free fall, approximately -10 m/s².

Velocity at the Highest Point

At the highest point of its trajectory, a thrown object has zero velocity but gravitational acceleration is still acting on it.

Displacement

The distance an object travels in a specific direction during its motion.

Motion of an Object Thrown Upward

An object thrown straight up will slow down, stop briefly at its peak, and then speed up as it falls back down.

Formula for Final Velocity (V)

V = V₀ + gt, where V₀ is the initial velocity, g is the acceleration due to gravity, and t is time.

Distance Formula for Free Fall

d = V₀t + 1/2gt², used to calculate the distance fallen by an object.

Highest Point Motion

At the highest point of projectile motion, the object's velocity is 0 m/s but it still has acceleration due to gravity.
