What is the definition of speed?
Speed is the distance traveled per unit of time.
True or False: Velocity is a scalar quantity.
False
What is the formula for calculating average speed?
Average speed = Total distance / Total time
Fill in the blank: The unit of acceleration is _______.
meters per second squared (m/s²)
What does a distance-time graph represent?
A distance-time graph shows how distance changes with time.
What is the difference between distance and displacement?
Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position.
Multiple Choice: Which of the following is a vector quantity? A) Speed B) Distance C) Velocity D) Time
C) Velocity
True or False: An object moving in a circle at constant speed is accelerating.
True
What does a velocity-time graph show?
A velocity-time graph shows how velocity changes with time.
Fill in the blank: The formula for acceleration is _______.
Acceleration = (Final velocity - Initial velocity) / Time
What is uniform motion?
Uniform motion occurs when an object moves at a constant speed in a straight line.
Multiple Choice: Which of the following best describes deceleration? A) Increase in speed B) Decrease in speed C) Constant speed D) Circular motion
B) Decrease in speed
What is the significance of the slope in a distance-time graph?
The slope represents the speed of the object.
True or False: A negative acceleration indicates that an object is slowing down.
True
What is the term for the rate of change of velocity?
Acceleration
