Equations of 1 -D Motion

Equations for uniform acceleration Where s is displacement (m) v is the final velocity

Equations for uniform acceleration Where s is displacement (m) v is the final velocity (m s-1) u is the initial velocity (m s-1) a is the acceleration (m s-2) t is the time (s)

Equations of motion When solving problems using these equations, it is important that you

Equations of motion When solving problems using these equations, it is important that you think about the problem, and try and visualise what is happening. The following steps are advisable. Step 1: Draw a simple diagram of the situation Step 2: Neatly write down the information that has been given in the questions, using positive and negative values to indicate directions. Convert all units to SI form. Step 3: Select the equation that matches your data. Step 4: Use the appropriate number of significant figures in your answer. Step 5: Include units with the answer and specify a direction if the quantity is a vector.

Equations of motion Example: A snowboarder in a race is travelling at 10 m

Equations of motion Example: A snowboarder in a race is travelling at 10 m s -1 as he crosses the finishing line. He then decelerates uniformly until coming to rest over a distance of 20 m. a. What is his acceleration as he pulls up?
