Q: Answer the following question given this paragraph: One dimensional motion describes objects moving in straight lines. Speed is a scalar measure of how quickly an object is moving along this line. Velocity is speed with a direction, making it a vector. If an object's velocity changes with time, the object is said to be accelerating. When restricted to one dimension, there are only two possible directions for the velocity and acceleration vectors to point in. As we'll see in the next chapters, understanding an object's acceleration is the key to understanding its motion. Q: What is the term for a scalar measure of how quickly an object is moving along this line? A: | OPTIONS:
- velocity
- motion
- force
- speed
A: speed
