Last Lecture Review

• This week– Position– Change in position wrt time– Change in velocity wrt time

Lecture overview

• Kinematic equations for constant accelerationwe are going to develop (derive) useful

equations for solving constant acceleration problems

kinematics

• Branch of classical mechanics that describes the motion of points and objects, and systems of objects, without consideration of the cause of motion

Constant acceleration

• Kinematic equations – 1) – 2) – 3) – 4) • The o subscript represents values at time zero

𝑣=𝑣𝑜+𝑎𝑡

𝑣=𝑣0+𝑣2

𝑥=𝑥𝑜+𝑣0𝑡+12 𝑎𝑡

2

𝑣2=𝑣02+2𝑎 (𝑥−𝑥0 )
