Scalar & Vectors Flashcards
What are the two types of quantities?
Vector and scalar quantities.
What are scalar quantities?
Scalars are quantities that have magnitude but not direction.
What are vector quantities?
Vectors are quantities that have both magnitude and direction.
What are examples of scalar quantities?
Distance, speed, mass, energy, volume, density, temperature, power.
What are examples of vector quantities?
Displacement, velocity, weight, force, acceleration, momentum.
What is distance?
Distance is a measure of how far an object has travelled, regardless of direction.
What is displacement?
Displacement is a measure of how far it is between two points in space, including the direction.
What is speed?
Speed is a measure of the distance travelled by an object per unit time, regardless of the direction.
What is velocity?
Velocity is a measure of the displacement of an object per unit time, including the direction.
How can vector quantities be represented?
Vector quantities can be represented by arrows.
What does the length of the arrow represent in vector quantities?
The length of the arrow represents the magnitude.
What does the direction of the arrow indicate in vector quantities?
The direction of the arrow indicates the direction.
Why are forces considered vector quantities?
Forces are vector quantities because they have both magnitude and direction.
