Question

which of the following statements are true about velocity? select two correct answers
a. velocity can be negative
b. velocity is equal to speed
c. velocity is the rate of change of distance
d. velocity depends on direction

Explanation:

• Velocity is a vector quantity. A vector quantity has both magnitude and direction. If the direction is opposite to the chosen positive direction, velocity can be negative. So, statement A is true.
• Speed is a scalar quantity (only has magnitude), while velocity is a vector quantity. They are not the same. So, statement B is false.
• Velocity is the rate of change of displacement (a vector quantity which considers direction), not distance (a scalar quantity). So, statement C is false.
• As velocity is a vector, it depends on direction. So, statement D is true.

Answer:

A. velocity can be negative, D. velocity depends on direction
