Practice Velocity in Physics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The rate of change of position with respect to time, including both magnitude and direction.
How fast something is moving AND which way it's headingβdirection is essential.
Example 1
easyA car travels 150 \text{ m} east in 10 \text{ s}. What is its average velocity?
Example 2
mediumA cyclist rides 200 \text{ m} north in 40 \text{ s}, then 200 \text{ m} south in 60 \text{ s}. What is the average velocity and average speed?
Example 3
mediumA particle's position is given by x(t) = 3t^2 + 2t. What is the instantaneous velocity at t = 4 \text{ s}?
Example 4
mediumA car accelerates from 10 \text{ m/s} to 30 \text{ m/s} in 5 \text{ seconds}. Find the average velocity.
Example 5
mediumA car drives 120 \text{ km} north in 1.5 \text{ hours}, then 80 \text{ km} south in 1 \text{ hour}. Find: (a) average speed, (b) average velocity.
