Understanding Vectors and Scalars

What is the primary difference between a vector and a scalar?

• Vectors have magnitude only, while scalars have both magnitude and direction.

• Vectors have both magnitude and direction, while scalars have magnitude only.

• Vectors are always larger than scalars.

• Scalars are always measured in meters.

Which of the following is an example of a scalar quantity?

• Displacement

• Velocity

• Acceleration

• Mass

Why is speed considered a scalar quantity?

• Because it is always measured in kilometers per hour.

• Because it has both magnitude and direction.

• Because it is a measure of how fast an object is moving in a specific direction.

• Because it has magnitude only and no direction.

Which of the following is NOT a vector quantity?

• Acceleration

• Velocity

• Force

• Time

What additional information does velocity provide compared to speed?

• Magnitude

• Distance

• Direction

• Time

How is the magnitude of a vector represented graphically?

• By the direction of the arrow

• By the length of the arrow

• By the color of the arrow

• By the width of the arrow

What happens to a vector if it is rotated 90 degrees?

• It becomes a scalar.

• It remains the same vector.

• It becomes a negative vector.

• It changes direction but keeps the same magnitude.

If two people push a box with equal force in opposite directions, what is the net force on the box?

• The box moves to the left.

• The box moves to the right.

• The net force is zero.

• The box moves upwards.

• Speed, Velocity, Distance

• Distance, Mass, Displacement

• Force, Acceleration, Time

• Displacement, Acceleration, Mass
