Velocity | Acceleration | Interpretation

rightward | rightward | Speed up to the right

leftward | rightward |Slow down to the left

leftward | leftward | Speed up to the left

rightward | leftward | Slow down to the right

Uniform Motion

• Velocity is constant.

• The same distance is covered for every time interval.

• Acceleration is zero.

Uniformly Accelerated Motion

• Velocity is changing.

• Distance covered is

increasing/decreasing for every time interval.

• Acceleration is constant

Equations for Uniformly Accelerated Motion

1. 𝒗𝒇= 𝝂𝒊 + 𝒂 𝒕

2. 𝒅 =(𝒗𝒇 + 𝒗𝒊/𝟐) 𝒕

3. 𝒗𝒇²= 𝒗𝒊² + 𝟐𝒂𝒅

4. 𝒅 = 𝒗𝒊•𝒕 +𝟏/𝟐 (𝒂𝒕²)
