Flashcard 1: Is displacement a scalar or vector?
Answer: Displacement is a vector. Displacement has both magnitude and direction.
Flashcard 2: Is mass a scalar or vector?
Answer: Mass is a scalar. Mass only has magnitude, no direction.
Flashcard 3: How do you add two vectors?
Answer: Use the head-to-tail method. Connect tail of second to head of first.
Flashcard 4: Which is a scalar: volume or velocity?
Answer: Volume is a scalar. Volume only has magnitude, no direction.
Flashcard 5: What kind of quantity is force?
Answer: Force is a vector quantity. Force has both magnitude and direction.
Flashcard 6: Choose the scalar: mass or force?
Answer: Mass is a scalar. Mass has no direction, force has direction.
Flashcard 7: Choose the vector: acceleration or temperature?
Answer: Acceleration is a vector. Acceleration has direction, temperature does not.
Flashcard 8: Which is a vector: torque or pressure?
Answer: Torque is a vector. Torque has direction, pressure does not.
Flashcard 9: What does the direction of a vector arrow represent?
Answer: The direction represents the vector's direction. The arrowhead points in the vector's direction.
Flashcard 10: What kind of quantity is time?
Answer: Time is a scalar quantity. Time has magnitude but no direction.
Flashcard 11: What is the magnitude of a vector?
Answer: Magnitude is the length of the vector. Also called the absolute value of the vector.
Flashcard 12: What does the length of a vector arrow represent?
Answer: The length represents the magnitude. Longer arrows indicate larger magnitudes.
Flashcard 13: What determines a vector's direction?
Answer: The direction of the arrow determines it. Arrow direction shows which way vector points.
Flashcard 14: Identify a scalar: power or momentum?
Answer: Power is a scalar. Power has no direction, momentum does.
Flashcard 15: Which is a scalar: energy or momentum?
Answer: Energy is a scalar. Energy has no direction, momentum does.
Flashcard 16: Which is a vector: electric charge or electric field?
Answer: Electric field is a vector. Electric field has direction, charge does not.
Flashcard 17: How do you add two vectors?
Answer: Use the head-to-tail method. Connect tail of second to head of first.
Flashcard 18: What is the difference between distance and displacement?
Answer: Distance is scalar; displacement is vector. Distance is total path; displacement is net change in position.
Flashcard 19: What is a scalar quantity?
Answer: A scalar quantity has magnitude only. Examples include mass, speed, time, and energy.
Flashcard 20: State the SI unit for displacement.
Answer: The SI unit for displacement is meter (m). Same as distance since both measure length.
Flashcard 21: Identify a vector: distance or displacement?
Answer: Displacement is a vector. Displacement includes direction from start to end.
Flashcard 22: What is a vector quantity?
Answer: A vector quantity has both magnitude and direction. Examples include velocity, force, and displacement.
Flashcard 23: Which is a scalar: temperature or acceleration?
Answer: Temperature is a scalar. Temperature has no directional component.
Flashcard 24: State the SI unit for distance.
Answer: The SI unit for distance is meter (m). Same as displacement since both measure length.
Flashcard 25: Which quantity can be negative: speed or velocity?
Answer: Velocity can be negative. Negative indicates direction opposite to positive reference.
Flashcard 26: State the formula for average speed.
Answer: AverageĀ speed=totalĀ timetotalĀ distanceā. Uses total distance traveled along the path.
Flashcard 27: Is velocity a scalar or vector?
Answer: Velocity is a vector. Velocity includes both speed and direction.
Flashcard 28: Identify a scalar: speed or velocity?
Answer: Speed is a scalar. Speed only indicates how fast, not direction.
Flashcard 29: What is the result of adding two vectors?
Answer: The result is a resultant vector. The sum combines both vectors into one.
Flashcard 30: Is speed a scalar or vector?
Answer: Speed is a scalar. Speed only indicates magnitude, not direction.
