[q] What is a scaler quantity?
[a] A scalar quantity has magnitude (size) only. Examples: mass, temperature, time, speed, distance.
[q] What is a vector quantity?
[a] A vector quantity has both magnitude (size) and direction. Examples: velocity, acceleration, force, displacement.
[q] What is the resultant vector?
[a] The resultant vector is the sum of two or more vectors.
[q] What are examples of physical quantities can be represented as vectors?
[a] Displacement, Velocity, Acceleration, Force, Momentum
[q] What are examples of physical quantities that can be represented as scalars?
[a] Mass, work, energy, power
[q] What do you do for vector addition (vectors A and B)
[a] Put the tip of vector A to the end of vector B and find the third side to find the resultant vector
[q] What do you do for vector subtraction (vector A – vector B)
[a] Flip vector B, put the tip of vector A to then end of vector B and find the third side to find the resultant vector
