Acceleration Due to Earth's Gravity Is -9

question 21

Multiple Choice

Acceleration due to Earth's gravity is -9.8 m/s². Which part of this number gives the information on direction, making it a vector quantity?

• A)We know it is a vector quantity because the seconds are squared in the units.
• B)We know it is a vector quantity because the negative sign tells us the acceleration is upward.
• C)We know it is a vector quantity because the negative sign tells us the acceleration is downward.
• D)We know it is a vector quantity because the negative sign tells us the magnitude of the acceleration.
