Detailed explanation-1: -Vector: These are the quantities that are described by both magnitude and direction. Examples of vectors are velocity, acceleration, force, etc.
Detailed explanation-2: -Force = Mass × Acceleration. As acceleration is a vector quantity, so force will also be a vector quantity.
Detailed explanation-3: -Velocity is a vector quantity having both magnitude and a direction.
Detailed explanation-4: -Velocity and acceleration are vector quantities, so they have both magnitude and direction. If the speed of an object remains the same but it changes direction, then the object is accelerating.
Detailed explanation-5: -Force is a vector quantity because it actually does depend in which direction you apply the force. The force can be seen physically as a push or a pull. Some examples of vector quantities include force, velocity, acceleration, displacement, and momentum.
