Question

which of the following is not correct for an object moving along a straight path in accelerated motion
A- ITS SPEED KEEPS CHANGING
B- ITS VELOCITY ALWAYS CHANGES
C- IT ALWAYS GOES AWAY FROM EARTH
D- A FORCE IS ALWAYS ACTING ON IT

Answer 1

It is option C- It always goes away from the earth. 
An object that is moving along a straight path in an accelerated motion can change its speed, and also its velocity, as it is in a straight line. A force is surely acting on the body. But, it cannot go away from the earth.

Answer 2

Answer:

It always goes away from the earth, that is option (d) is incorrect.

Explanation:

For a body in motion along a straight line,

the speed of the body keeps changing.

Since the body is in accelerated motion, it will show a change in velocity.

Since Acceleration is the rate of change of velocity, the velocity of the body will change with time t.

There is always a downward and upward force acting on a body.

When the body is in accelerated motion, it does not always go away from the earth. The gravitational force of the earth always pulls all the bodies closer to it.

Hence. the incorrect option is option d.
