Determine which of the following are vector quantities. VelocityAccelerationDisplacementSpeed

Vector quantities are those that have both magnitude and direction.

1. Velocity: This is a vector quantity because it involves both the speed an object is moving and the direction in which it is moving.

2. Acceleration: This is also a vector quantity because it involves a change in velocity, which includes both speed and direction.

3. Displacement: This is a vector quantity as well because it involves both the distance an object has moved and the direction in which it moved.

4. Speed: This is not a vector quantity. Speed only involves the magnitude of how fast an object is moving, not the direction in which it is moving. Therefore, it is a scalar quantity, not a vector quantity.
