Question

classify the following variables as either a scalar or a vector.
speed
displacement
distance
acceleration
velocity
previous

Explanation:

• Speed: It only has magnitude (e.g., \(50\space km/h\)). So, it is a scalar.
• Distance: It only measures how much ground an object has covered (e.g., \(100\space m\)). So, it is a scalar.
• Displacement: It has both magnitude (e.g., \(50\space m\)) and direction (e.g., towards the north). So, it is a vector.
• Acceleration: It has both magnitude (e.g., \(2\space m/s^{2}\)) and direction (e.g., in the direction of motion). So, it is a vector.
• Velocity: It has both magnitude (e.g., \(30\space m/s\)) and direction (e.g., east - ward). So, it is a vector.

Answer:

Speed: Scalar
Distance: Scalar
Displacement: Vector
Acceleration: Vector
Velocity: Vector
