Question

Which of the following information is necessary to describe an object's motion?

Answer 1

Answer: The correct option is B.

Explanation: To describe the motion of an object, we use the equations of motion.

1. $v=u+at$
2. $s=ut+\frac{1}{2}at^2$
3. $2as=v^2-u^2$

From the above equations, we require position, speed and direction through which we an calculate the displacement, velocity and acceleration.

To calculate the complete motion of an object, we require all the three factors.

Hence, the correct option is B.

Answer 2

The answer is B) position,direction & speed hope i helped<span />
