Speed is a scalar quantity which refers to "how fast an object is moving."
2. What are the different types of speed?
There are high speed, zero speed and low speed.
3. How is speed different than velocity?
Speed is a scalar quantity which refers to "how fast an object is moving" and Velocity is a vector quantity which refers to "the rate at which an object changes its position."
4. How would you define acceleration?
Acceleration is a vector quantity which is defined as "the rate at which an object changes its velocity." An object is accelerating if it is changing its velocity.
5. Give a real-life example of speed, velocity, and acceleration?
Speed: A car drives with 100 mph
Velocity: A person moving rapidly - one step forward and one step back - always returning to the original starting position.
Acceleration: A car drives at the beginning with 50 mph. After that it accelerated to 100 mph!
