What is the formula for calculating velocity?
Think about how displacement and time are involved.
If an object has a velocity of 10 m/s and it accelerates at 2 m/s² for 3 seconds, what is the final velocity?
Use the formula v = u + at.
What is the formula for acceleration?
Focus on how velocity changes with time.
True or False: Velocity can have both speed and direction.
Think about how scalar and vector quantities differ.
A car accelerates from 30 m/s to 90 m/s over a time span of 6 seconds. Calculate its acceleration and the distance traveled during the acceleration.
Use the acceleration formula first and then apply the distance formula.
An object moving with a velocity of 50 m/s comes to a complete stop in 5 seconds. Determine the acceleration and distance covered before stopping.
Remember that the initial velocity is positive and the final velocity is zero.
