***Part 1: Velocity and Acceleration
1) Speed is a scalar measurement of distance over time. Velocity is a vector measurement of speed and direction.
2) What is the formula for calculating average velocity?
total distance over total time
3) What is acceleration?
the rate of which an object changes velocity or an increase or decrease in the rate of speed of a moving body.
4) What is the formula for average acceleration?
Final velocity- initial velocity/final time- initial time
***Part 2: Travel Graphs
1) What is the formula for calculating speed?
distance over time
2) What is the difference between speed and velocity?
velocity has direction, speed doesn't.
3) How is constant velocity shown on a graph?
When it is a horizontal straight line
4) How is acceleration shown on a graph?
When it is a diagonal straight line
***Part 3: Force and Motion
1) Match the term with its definition.
-Negative acceleration: the decrease in speed
-Speed: Rapidity in moving, going, traveling, proceeding, or performing.
-Distance: The amount of space between two things
-Motion: The action or process of moving or of changing place or position
-Velocity: measure of the speed and direction of an object
2) Explain the difference between speed and acceleration.
Speed is the rapidity in movement, while acceleration is the increase or decrease of speed and/or the change of direction in an object.
