Free Fall and Kinematics

Free Fall

• when the only force acting on an object is gravity

• when a falling object experiences air resistance

• the horizontal notion of an object across a surface

• the final velocity a falling object achieves

The maximum velocity an object can achieve when falling through air

• terminal velocity

• final velocity

• initial velocity

• acceleration

Equations that quantify motion of an object without respect for cause

• kinematics

• kinetic energy

• potential anergy

• distance/time

Energy of an object in motion

• kinematics

• kinetic energy

• potential anergy

• distance/time

A falling object moves along the _________axis

• y

• x

Distance can be found by

• W = m x g

• terminal velocity

• air resistance

In a vacuum, all objects fall

• at the same rate

• at a different rate

Final velocity at time t can be determined by

• F = m x a

• m x v

• m x g x h

Momentum

• F = m x a

• m x v

• m x g x h

Potential energy

• F = m x a

• m x v

• m x g x h
