Question

If a partical is moving along a straight line with increasing speed, then its acceleration is ( A) Negative
( B) positive
(C) both A and B
(D) may be decreasing
pls ans correctly and give full explanation pls pls pls pls ​

Answer 1

Explanation:

If a particle is moving along a straight line with increasing speed then its acceleration is positive. ... When a body is moving in a straight line with increasing speed, then it signifies that the velocity in result is also increasing with constantly.

Answer is ( B ) Positive

Answer 2

Answer:

• If a particular is moving along a straight line with increasing speed, then it's acceleration is positive

Explanation:

• If a particle is moving along a straight line with increasing speed then its acceleration is positive The reason for its acceleration being positive is because the velocity with which it is moving is positive. When a body is moving in a straight line with increasing speed, then it signifies that the velocity in result is also increasing with constantly.

Additional information:-

• In option (B) it contains the word 'may' so the statement only needs to be true sometimes. It is true, for example, when a particle moves right with increasing speed due to a force acting to the right, even though the magnitude of of the force is decreasing. The decreasing force decreases the acceleration, but the acceleration is still positive and causes speed to increase.
