Further motion concepts Flashcards
What is the formula for calculating speed?
Speed = Distance / Time
True or False: Velocity is a scalar quantity.
False
Fill in the blank: The unit of acceleration is _____.
meters per second squared (m/s²)
What does a negative acceleration indicate?
It indicates a decrease in velocity.
Multiple choice: What is the acceleration of an object in free fall near the Earth’s surface? A) 10 m/s² B) 9.81 m/s² C) 15 m/s²
B) 9.81 m/s²
What is the difference between distance and displacement?
Distance is a scalar quantity measuring the total path length, while displacement is a vector quantity measuring the shortest path from the initial to final position.
True or False: An object moving in a circular path at constant speed has zero acceleration.
False
What does a velocity-time graph represent?
It represents an object’s velocity as a function of time.
Fill in the blank: The area under a velocity-time graph represents _____.
distance traveled
Multiple choice: Which of the following represents uniform acceleration? A) A car speeding up at a constant rate B) A car moving at a constant speed C) A car slowing down
A) A car speeding up at a constant rate
What is the formula for calculating acceleration?
Acceleration = (Final Velocity - Initial Velocity) / Time
True or False: A straight line on a velocity-time graph indicates constant velocity.
True
What is the term for the rate of change of velocity?
Acceleration
Fill in the blank: The term used to describe the change in position over time is called _____.
motion
Multiple choice: If an object is thrown upwards, what is the direction of its acceleration? A) Upwards B) Downwards C) No acceleration
B) Downwards
What is the significance of the slope of a velocity-time graph?
The slope represents acceleration.
True or False: An object in motion will continue to move at a constant speed unless acted upon by an external force.
True
What is the formula for calculating distance using a velocity-time graph?
Distance = Area under the velocity-time graph
Fill in the blank: In free fall, the only force acting on the object is _____.
gravity
Multiple choice: Which of the following is a vector quantity? A) Speed B) Distance C) Displacement
C) Displacement
What does a curved line on a velocity-time graph indicate?
It indicates changing acceleration.
True or False: The total distance traveled can be greater than the magnitude of the displacement.
True
What is the effect of air resistance on a falling object?
It decreases the acceleration of the object.
Fill in the blank: An object that is accelerating is experiencing a change in _____.
velocity
Multiple choice: What is the term for the point at which an object stops accelerating and falls at a constant speed? A) Terminal velocity B) Maximum speed C) Acceleration limit
A) Terminal velocity
