1. Speed is a scalar measurement of distance over time. Vector is a measurement of direction. Speed does not have direction. Velocity is a vector measurement of distance and time.
2. What is the formula for calculating average velocity?
The formula is total distance over total time.
3. What is acceleration?
Acceleration is any change in velocity. Velocity = distance over time.
4. What is the formula for average acceleration?
A=Vf - Vi
t
Acceleration = Velocity (final) - Velocity (initial)
time

Part 2: Travel Graphs
1. What is the formula for calculating speed?
Speed = distance divided by time. (NO DIRECTION)
2. What is the difference between speed and velocity?
Speed does not have direction, while velocity is speed and direction.
3. How is constant velocity shown on a graph?
A velocity-time graph has the velocity or speed of an object on the vertical axis and time on the horizontal axis. The distance traveled can be calculated by finding the area under a velocity-time graph.
4.How is acceleration shown on a graph?
Acceleration is the gradient of a velocity-time graph and on curves can be calculated using chords or tangents.

Part 3: Force and Motion
1. Match the term with its definition.
A: Velocity: measure of the speed and direction or an object
B: Negative Acceleration: a decrease in speed. Example: car slowing down.
C: Motion: the action or process of moving or of changing place or position
D: Speed: rapidity in moving, going, travelling, proceeding, or performing
E: Distance: the amount of space between two things
2. Explain the difference between speed and acceleration.
Speed is the rapidity of movement and the constant motion. Acceleration is the increase of speed, a change in speed. (CHANGE IN VELOCITY)
