Which of the following statements are false about the motion of particle?AParticle may reverse the direction of motionBDistance covered is not equal to magnitude of displacementCThe magnitude of average velocity is less than average speedDAll of the above

In a two dimensional motion, instantaneous speed v0 is a positive constant. Then which of the following are necessarily true?a) the average velocity is not zero at any timeb) average acceleration must always vanishc) displacements in equal time intervals are equald) equal path lengths are traversed in equal intervals

An object moves in a circular path at a constant speed. Which of the following is true? A. The car’s acceleration is zero because it has a constant speed B. The car’s acceleration is not zero and causes the car to slow down C. The car’s acceleration is not zero and causes the car to speed up D. The car’s acceleration is not zero and causes the change in the direction of the car’s velocity E. None from the above

Under which of the following conditions is the magnitude of the average velocity of a particle moving in one dimension smaller than the average speed over some time interval? 1 pointThere are no conditions for which this is trueA particle moves in the +𝘹 direction and then reverses its directionA particle moves in the +𝘹 direction without reversingA particle moves in the −x direction without reversing

Which of the following statements are true regarding displacement, velocity, and acceleration for an object in 1-D motion?  (Choose all that apply)  Group of answer choicesIf an object is speeding up, then its acceleration has the same sign (positive or negative) as its velocity.If an object is speeding up, then the sign (positive or negative) of its acceleration is opposite to the sign of its velocity.If an object is slowing down, then the sign (positive or negative) of its acceleration is opposite to the sign of its velocity.If an object is slowing down, then its acceleration has the same sign (positive or negative) as its velocity.If an object is speeding up, then its displacement has the same sign (positive or negative) as its velocity.If an object is speeding up, then the sign (positive or negative) of its displacement is opposite to the sign of its velocity.If an object is slowing down, then its displacement has the same sign (positive or negative) as its average velocity.If an object is slowing down, then the sign (positive or negative) of its displacement is opposite to the sign of its average velocity.
