The rate at which velocity changes is called ________________________.

Acceleration Acceleration = the rate at which velocity changes with time A measure of how quickly velocity is changing If velocity doesn’t change, there.

Acceleration Acceleration is the rate of change of velocity with respect to time. a = Δv = vf – vi Δt tf – ti The units for acceleration are m/s2.

Bellwork How is velocity different from speed? Give an example.

Acceleration speed direction vector speed free fall _______________________ can be described as changes in __________________, changes in ___________________, or changes in both. This means acceleration is a _____________. An example of change in ___________ is a ____________________. speed direction vector speed free fall

5. The formula for acceleration is shown below: ∆ change in velocity 𝑎𝑐𝑐𝑒𝑙𝑒𝑟𝑎𝑡𝑖𝑜𝑛=𝑎= = (𝑣𝑓−𝑣𝑖) 𝑡 Time interval

Write acceleration including direction: Little Timmy rides his bicycle north to school each day. His initial velocity is 0 m/s. After 2 minutes, his velocity is 6 m/s. Find the kid’s acceleration in meters per second squared (m/s2). Remember to include direction. Vi= 0m/s t= 2 min Given: Unknown: a =? Vf= 6m/s Conversions: 2 min x 𝟔𝟎 𝒔 𝟏 𝒎𝒊𝒏 = 120 s Solve: a = (𝒗𝒇−𝒗𝒊) 𝒕 = 𝟔−𝟎 𝟏𝟐𝟎 = 0.05 m/s2 0.05m/s2 north Write acceleration including direction:
