Answers
Answer:
force is the answer
Explanation:
because all of options are motions but force is not a motion
TRANSLATORY MOTION:
motion in which all points of a moving body move uniformly in the same line or direction.
FORCE:
a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.
F = m×a
OSCILLATORY MOTION:
A motion repeating itself is referred to as periodic or oscillatory motion. An object in such motion oscillates about an equilibrium position due to a restoring force or torque.
WEIGHT OF A BODY:
Weight is a force with which earth attracts objects."The weight W of a body is equal to the magnitude Fg of the gravitational force on the body." The gravitational acceleration varies from place to place.
