which of the following statement is not correct for an object moving along a straight path in an accelerated motion?a.it's speed keeps changing b.its velocity always changes c.it always goes away from the earth d. a force is always acting on it ( the correct answer I will mark as brainleast)
Answers
Answer:
Also, speed is equal to the magnitude of velocity for a particle moving along a straight line. Hence, its speed is also always changing. ... A body under acceleration on a straight line may be moving towards or away from earth. Hence, option c is wrong.
Answer:
Option (c) it always goes away from the earth is correct.
Concept:
Speed - Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
Velocity - The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction. Since it is a vector quantity, the definition of velocity requires both magnitude (speed) and direction. Its SI equivalent is the meter per second (). A body is considered to be accelerating if the magnitude or direction of its velocity changes.
Given:
A object moving along a straight path in an accelerated motion.
Find:
Which statement is not correct?
Solution:
Let's take the speed of an object = 10
Also take the velocity of an object = 10
As we know that speed is scalar quantity and velocity is vector quantity.
The statement in the question about an object moving more quickly down a straight line implies that the object is experiencing a force other than zero, which is increasing its velocity and speed. However, the force's direction is not specified, making it impossible to establish if it is travelling away from Earth.
Hence, the wrong statement is when an object moving along a straight path in an accelerated motion it always goes away from earth.
