4 cards from this section. Quick, good the night before a test.
What is the first equation of motion?
Consider how final velocity is calculated.
What do the symbols u, v, a, and t represent?
Think of a moving object starting and stopping.
What does the equation v = u + at represent?
Think about how speed changes over time.
True or False: The equation s = ut + 1/2at² includes initial velocity.
Review how distance incorporates both factors!
A cyclist accelerates from 5 m/s to 20 m/s over 15 seconds. Calculate the acceleration and the distance covered.
Use v = u + at to find acceleration and then use s = ut + ½ at² for distance.
An object falls from rest under gravity, gaining an acceleration of 9.8 m/s². What will be its velocity and distance after 4 seconds?
Apply both v = u + at and s = ut + ½ at² with the given acceleration.
