Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the definition of speed?A scalar quantity representing the rate of change of an object's position
2. What is the kinetic energy formula?KE = 1/2 mv², where m is mass and v is speed
3. How do we calculate average speed?To find average speed, divide the total distance by the total time. For example, if you run 10 meters in 5 seconds, your average speed is 2 meters per second.
4. Why is speed important for cars and airplanes?Faster cars and airplanes help people travel quickly, bring goods faster, and let emergency services reach places sooner.

Scalar Quantity: A quantity that has magnitude but no direction, such as speed or mass.
Vector Quantity: A quantity that has both magnitude and direction, such as velocity or force.
Special Relativity: Einstein's theory describing the relationship between space, time, mass, and energy at high speeds.
