What role does force play in the motion of an object?
What role does force play in the motion of an object?
- It is solely responsible for keeping objects at rest.
- It can cause an object to change its velocity if not counterbalanced. (correct)
- It has no effect if the object is moving at a constant speed.
- It can only maintain an object's current velocity.
How is force mathematically characterized?
How is force mathematically characterized?
- As an unmeasurable concept in physics.
- As a scalar quantity with magnitude only.
- As a quantity that describes only the direction of movement.
- As a vector quantity with both magnitude and direction. (correct)

Study Notes
Force Definition
- Force is an influence that changes an object's velocity if not opposed by other forces.
- Force precisely defines everyday ideas of pushing and pulling.
- Force is a vector quantity, meaning both magnitude (strength) and direction are crucial.
