4 cards from this section. Quick, good the night before a test.
What is the definition of velocity?
Think about how direction changes the description of how something moves.
What is the unit of acceleration in the SI system?
Consider how acceleration measures a change in speed over time.
What does acceleration indicate about an object?
Think about how acceleration affects the motion over time.
True or False: Velocity is a scalar quantity.
Remember the difference between vector and scalar quantities.
An object starts from rest and accelerates uniformly to a speed of 30 m/s in 6 seconds. How far does the object travel during this time?
Break it down into steps, calculate acceleration then apply it to the distance formula.
A skateboarder rolls down a ramp, increasing speed from 4 m/s to 16 m/s over 4 seconds. Calculate the skateboarder's acceleration and the distance traveled during the acceleration.
Calculate acceleration first, then determine distance using the appropriate formula.
