Question

In the kinematic equation v² - u² = 2(-a)s, why is acceleration negative?

पर्याय

• The object is moving backward

• The force is opposing or retarding the motion

• Velocity is negative

• The object has no mass

Answer 1

The force is opposing or retarding the motion

Eplanation:

Acceleration is negative because the force acting on the object is opposing its motion, causing it to slow down.
