Kinematic equations/Free fall

Kinematics

Equations that describe an object’s motion

For scenarios where acceleration changes

Break the scenario into multiple parts where each part has a constant acceleration

When velocity is constant

Acceleration is 0 m/s

Free fall

When an object is acted upon by gravity and only gravity

Magnitude of free fall acceleration on/near earth’s surface

9.80665 m/s²

As altitude increases

Free fall acceleration decreases

Latitude near the equator

Relative minimum

Latitude near earth’s poles

Relative maximum

Location near top of earth at sun/moon

Gravity is increased

Location near bottom of earth at sun/moon

Gravity is decreased

Free fall acceleration on moon

1.6 m/s²

Free fall acceleration on mars

3.7 m/s²

Free fall acceleration on jupiter

2.5 m/s², not on due to being a gaseous planet

If object is dropped

Initial velocity is 0m/s

When object is falling after being dropped

Final velocity is the moment velocity is no longer 0m/s

Initial velocity of an object thrown up

positive, up

Velocity at maximum height

0 m/s
