Which one of the following statements is not correct for an object mov...
- The question states an accelerated motion of an object along a straight line, this implies a non zero force is acting on the object, which is increasing its velocity and speed.
- However the direction of force is not given so it can’t be determined that it is moving away from the earth, Hence the correct answer is C.

Which one of the following statements is not correct for an object mov...
Explanation:
Speed and Velocity:
- In accelerated motion, the speed of an object keeps changing as it accelerates or decelerates.
- The velocity of an object in accelerated motion also changes as both speed and direction are components of velocity.
Force Acting on the Object:
- In accelerated motion, a force is always acting on the object to cause the acceleration according to Newton's second law of motion (F=ma).
Going Away from Earth:
- The statement that the object always goes away from the Earth is not correct. The motion of an object along a straight path in accelerated motion does not necessarily mean it is moving away from the Earth. The direction of the motion can be in any direction depending on the applied force and the initial conditions.
Therefore, the statement "It always goes away from Earth" is not correct for an object moving along a straight path in accelerated motion.
