What is the formula for final velocity in uniformly accelerated motion?
Think about the factors that change velocity over time.
If an object starts from rest, what is its initial velocity?
Recall what it means when an object is at rest.
What formula relates final velocity to initial velocity and acceleration?
Consider how velocity changes with time when acceleration is present.
True or False: The displacement of an object can be negative.
Think about how we define positive and negative directions.
An object starts from rest and accelerates uniformly at 5 m/s². How long will it take to travel 100 m?
Use the displacement equation for uniformly accelerated motion.
A cyclist accelerates from 8 m/s to 20 m/s over a distance of 100 m. Calculate their acceleration and time taken.
Break it into parts: first calculate acceleration, then use it to find time.
