What does a straight, diagonal line represent on a speed vs time graph?
constant acceleration
Define scalar.
A quantity that includes only magnitude (size).
What does a diagonal, straight line represent on a distance vs time graph?
constant speed
What does "delta v" represent?
change in velocity (final velocity minus initial velocity)
Explain the difference between speed and acceleration.
Speed only considers the distance and object moves in a given time, which acceleration includes how quickly the speed is changing in a given time with direction
How quickly an object is moving at a certain time is its...
instantaneous speed
How can you tell an object has moved?
The object's position changes compared to a reference frame.
Explain why a car turning a corner at a constant speed of 20 m/s is not traveling at a constant velocity.
Because the direction of the car is changing, velocity is not constant (vector).
Describe the motion of the object using the graph.
