Representing Motion: Freefall and Projectile Motion

Flashcards covering the concepts of freefall, acceleration, and projectile motion discussed in the lecture.

Freefall

When gravity is the only significant force acting on an object, and other forces like air resistance are negligible.

Freefall Acceleration on Earth

On Earth, objects in free fall experience a downward acceleration of approximately 10 meters per second squared.

Freefall on the Moon

In the absence of air resistance, all objects fall with the same acceleration, regardless of their mass or other properties.

Constant Acceleration

The rate at which the velocity of a falling object changes over time, remaining constant in free fall.

Freefall Acceleration on the Moon

On the moon, downward acceleration is approximately 1.6 meters per second squared.

Freefall on Earth (with negligible air resistance)

The effects of air resistance are negligible, and the downward acceleration is approximately 10 meters per second squared.

Freefall Acceleration on Mars

On Mars, the acceleration due to gravity is approximately 3.7 meters per second squared.

Average Speed of a Projectile on the Way Up

The average of its speed at the top (0 m/s) and its speed at the bottom, multiplied by the time spent going up yields maximum height.
