AA push or pull with magnitude and direction
BA scalar measuring how fast a body moves
CA vector with magnitude but no direction
DA scalar equal to the mass of a body
Answer & Solution
Correct answer: A. A push or pull with magnitude and direction
1. A force is a push or a pull on an object with a specific magnitude and direction.
2. Because it has both magnitude and direction it is a vector quantity.
3. Forces add head to tail like other vectors, so a total force can be found graphically.
4. Any option that calls force a scalar contradicts the way forces add.
